What can be cooked from squid: quick and tasty

The development of new heating systems is ongoing. Modernization of the boiler, improving the parameters of radiators and pipes. However, along with new methods of maintaining a comfortable temperature in a living room, alternative methods are being developed. One of them is water heaters for home heating: flow-through, electric. At first glance, they are only intended to provide hot water supply. But is it? To understand this issue, it is necessary to analyze the technical and operational qualities of these schemes.

The principle of operation of a water heater for heating

Usually the boiler is used only for hot water supply. Structurally, it is a container, inside which heating heating elements are located. When filled, they heat the liquid to the required level. Then, through the outlet pipe, it enters the plumbing fixtures - mixers in the kitchen, in the bathroom. But in addition to this, you can make an additional circuit for heating the air in the rooms.

Before using the water heater for heating, the following conditions must be met:

Provide liquid circulation in the pipes. If the container is constantly filled with running water, the heating agent heating rate will be minimal. Make a closed loop with circulation;
Installation of the necessary heating elements - an expansion tank, a pump and valves;
Provide for the possibility of replenishing the coolant from the water supply system.

But how to make heating from a water heater if it is not structurally designed for this? The specificity of the design and practical implementation of this task lies in the simultaneous use of the same water for DHW heating of the room. Therefore, first of all, it is necessary to install a pump of a certain power, which would ensure uniform heating by the water heater by the constant movement of liquid in the pipes. Then a filtration system should be made. Before entering the circuit, the water must be purified, since a large amount of impurities is characteristic of the flow-through, which negatively affects the state of pipes and heating devices.

Before purchasing an electric water heater, you need to find out if it is suitable for heating. First of all, this concerns the availability of convenient control with the ability to quickly regulate the temperature level in the tank.

Is it worth installing water heaters from the heating system if there are electric boilers specially designed for this? Consider the characteristics of both systems.

Water heater or electric boiler?

The idea to use instantaneous water heaters for heating arose even when the first electric boilers appeared on the market. But most often, electric boilers are installed, which are designed specifically for heating. You can find out the relevance of installing instantaneous water heaters from the heating system after a comparative analysis of these devices with boilers.

An important indicator is the efficiency of the system - the ratio of the heat energy received to the consumed one. In this regard, electric boilers are much more efficient - their figure reaches 90%. At the same time, most electric instantaneous water heaters for heating have an efficiency not exceeding 70%. This is due to the specifics of the structures and the method of increasing the temperature of the coolant. Next, you should take into account certain performance characteristics.

The use of an instantaneous water heater is only possible for closed systems with forced circulation. This is due to the specifics of the device.

The method of heating water with a water heater

Modern electric water heaters for heating work on the same principle as boilers. A large sealed container is filled with water, which is heated using electric heating elements. In this case, heat loss occurs through the body.

In boilers, the coolant increases the temperature when passing through a heat exchanger with a built-in heating element. Since the volume of this chamber is relatively small, heating occurs quickly. At the same time, heat losses are minimal. It should also be noted that in most cases the design already has a circulation pump, an expansion tank and a convenient control system. In addition to the latter, electric water heaters for heating of the VEO type do not have these elements.

Heating inertness

The rate of temperature rise of water in pipes for electric boilers is quite high. The average heating time from 25 degrees to 60 is 15-20 minutes, depending on the volume of the system. In this regard, heating with a water heater is significantly inferior to the traditional one. In order for the volume of water in a boiler with a capacity of 150 liters to reach the desired temperature, it is necessary to wait about an hour. The main criteria affecting this indicator are the power of heating elements, the volume of the tank and the entire system as a whole.

However, when the electric boiler stops working, the water in the pipes cools down quickly. At the same time, in the water heater system, a large volume of hot liquid is in the tank and it will take several circulation cycles to cool it down. Those. in the event of an unexpected power outage, the coolant in the boiler system will still be hot for some time.

Summarizing these factors, you can determine the basic conditions for using an electric water heater for heating:

The area to be heated must be relatively small. This is due to the ratio of 1 kW of thermal energy per 10 square meters;
Good quality running water to preserve all heating elements;
To fill the tank, it is necessary to create the same pressure as in the water supply system - 4 atm. This applies only to those cases when a conventional boiler is installed that is not intended for heating from a water heater. In specialized models, the value of the minimum pressure is much lower - from 1.5 atm.

You can use an electric water heater to heat a house with a small area of up to 80 sq. First of all, this applies to country buildings.

The second way to use an instantaneous water heater for heating is to equip a floor heating system. But even in this case, it is necessary to carefully read the diagram for connecting the device to the pipeline.

Indirect heating boiler

An acceptable alternative to the above-described method of heating rooms with a boiler is indirect heating tanks. By the principle of operation, they are similar to the classic ones, but with one exception - a serpentine tube is located inside, which is connected to the heating system.

But how can such a water heater be used for heating? First, it should be remembered that it is only an additional source of heating the coolant. The main boiler is any type. For efficient operation of the indirect heating boiler, it is recommended to install it in front of the return pipe inlet to the boiler. Heat from the hot water supply will be transferred to the coolant in the coil. Thus, you can make the optimal temperature regime of the system.

They differ from electric water heaters for heating, type BEO, in low efficiency as the main source of heat generation. But this way you can reduce the current costs of the energy carrier. When choosing an indirect heating boiler, it is recommended to pay attention to these parameters.

The volume of the container. The area of contact of hot water with the coil depends on it. The larger it is, the more the coolant will heat up. The optimal volume should be 150 liters or more;
Power of heating elements. Directly affects the rate of water heating. On average, for every 50 liters of volume, a power of 2 kW is required;
Thermal insulation of the case. To minimize heat loss, it is better to choose models with a double wall, inside which there is a heater.

However, when organizing heating using a water heater of this type, the high cost should be taken into account.

For example, the popular Vaillant uniSTOR VIH R model with a volume of 200 liters will cost almost 20 thousand rubles. But this will be a better option than using a conventional water heater for heating.

Instantaneous water heater

An interesting solution for small areas are instantaneous electric water heaters for heating. Unlike boilers, they are capable of heating a small volume of water. The average performance of a relatively powerful 2 kW model will be 12 lit / min at a coolant temperature of 60 degrees.

Such structures are most often installed in summer cottages with non-permanent residence. Since heating can be made from a water heater, it is often used for its intended purpose - providing hot water. In this case, the system of pipelines for heating the coolant and DHW is common. The advantages of installing an instantaneous water heater as a heating device are:

Small size. It can be placed almost anywhere in the kitchen or bathroom;
The minimum indicator of inertness - the time for raising the temperature of the water in the pipes is short;
Convenient adjustment of temperature conditions, as well as the presence of a heating element shutdown system in the absence of water in the pipes;
A large selection of models that differ in both power and cost.

The main disadvantage of an instantaneous water heater for heating systems is the high consumption of electricity. Its constant use is impractical, as an exception, it is installed as an emergency way to maintain the temperature of the water in the pipes.

Self-production of a water heater for heating is not recommended. This is related to ensuring the safety of people living in the house.

Installation and selection of a heat carrier for a water heater

Before making heating from a water heater, it is necessary to calculate the optimal power. In this case, it is impossible to be guided by the nominal power of the installation. The main indicator is the time for heating the water to the desired temperature regime. In some models, it is limited to 20-30 minutes, but for most it is more than an hour.

Nowadays, owners of apartments or private houses often install boilers as an additional source of hot water. And after a while, some people think - is it possible to use a water heater as another element of the system. But for this you need to know all the details and the specifics of the operation of the unit. And the owner - to treat the installation of heating equipment with full responsibility.

Heating water

The usual model of a boiler is a cylindrical container, inside which elements that heat the liquid are located. To connect the device to water pipes, two special pipes must be cut. In one, water enters, and from the other it is discharged to the mixer. Therefore, some homeowners are wondering about the possibility of using the scheme to create a kind of heating system.

The parameters that are enough to supply the living space with hot water are not enough. It is almost impossible to organize autonomous heating using this device. In order for a water heater to start heating a private house, it must have a high percentage of power. According to experts, 1 kilowatt of thermal energy is required to heat 10 square meters. If we take as an example a house with an area of 100 sq. m, then to provide heat, you will need a device with a power of at least 10 kW. And you won't find such models anywhere in the daytime with fire.

But it is quite possible to purchase a boiler for equipping a small country house with heat. There are pitfalls here. Typically, users are faced with the following:

High rate of inertia. With a boiler tank capacity of 100 liters, and heating elements with a capacity of 2 kilowatts, it will take at least an hour and a half to heat water to 80 degrees. Circulation is not possible because it takes even longer (which is a lot of electricity used).
Tank displacement. Some owners believe that the larger the heater tank, the better: there is a lot of hot water, and it is possible to heat in parallel. But this is not the case. Constant heating will lead to the fact that the coolant will have different temperatures, and the device itself will soon become unusable.
High energy consumption. A boiler that is always on requires a lot of energy. An unpleasant surprise awaits homeowners when taking meter readings. Therefore, the round-the-clock connection of the water heater to the network will require a lot of money.

Recently, the issue of heating a private house with a boiler has become especially acute. The device is present in almost every living space, and not everyone is eager to buy and install a solid fuel boiler. But you can hardly do without it here - together these units create the so-called indirect heating.

The boiler is compatible with an electric boiler (and a water circuit). The fact is that they work on almost the same principles and have almost the same internal structure. Often both the one and the other apparatus are called "boilers".

If they want to install a conventional water heater as the main element for heating, homeowners may face a warranty problem from the manufacturer. This is due to the fact that the device is not used for its intended purpose.

Storage tank and water heater

The devices are similar to each other. The only difference between them is the internal water supply, which is connected directly to the heating system. Here the question arises regarding the place of the boiler in the heating of the premises.

If people approach the arrangement of heating in their homes correctly, they will equip the boiler as a heat accumulator. The carrier inside it will receive energy using a coil that is connected to the heating system. After turning off the electric boiler, the temperature will rise due to the water heater.

With proper equipment of the system, the boiler will give additional bonuses:

Hot water supply. Since the water from the device does not have any contact with the coolant, it can be safely used for household needs. Before this, a smart decision will be the correct ratio of boiler power to heat the house without disrupting the operation of the entire system.
Heating water using a built-in heating element. A constant temperature regime reigns inside the device, even when the boiler is disconnected from the electrical network. That is, for this you need to purchase a heater that works from an outlet.

Before purchasing, you should think about the main purpose of the purchase - it will be an additional source of hot water, a storage battery or two-in-one.

The storage tank can be made by hand. To reduce the percentage of heat losses, it is necessary to carry out procedures for the insulation of containers.

Calculations of the parameters of the tank and heating elements

First of all, you need to calculate the power of the boiler for heating the premises in the house. Experts offer several options for solving this problem. The simplest and most common is to read the recommendations from the manufacturer of the purchased boiler in the instructions.

It is worth remembering that the scheme of the entire heating system depends on this indicator. The first important parameter is power, measured in kW / h. For example, it equals one unit. After installing the device, its level remains unchanged for five hours. In this case, the mode is 75/50. Then the volume of the heater is calculated by the formula: V = 5 / (75-50) = 0. 5 m³ or 500 l.

By the same principle, you can choose a unit for heating a summer cottage, slightly reducing the indicators in the formula.

Installation and use for heating

At the end of all calculations and measurements, you can safely begin installing the boiler and introducing it into the heating system of the house. Before that, one question must be resolved - what place will the device take. This is an extremely important point in the modernization of the system. Professionals advise installing the boiler in close proximity to the boiler, then the temperature indicators will be quite optimal for heating the premises. And after that, you should study the instructions for the device, because everything is indicated there - from technical characteristics to recommendations from manufacturers.

Even with strict adherence to all the tips, the owners often face difficulties in introducing a water heater into the heating system. The situations are as follows:

Hot water supply. The ideal location for a solid fuel boiler is a boiler room or a room where the main communication mechanisms in the house are concentrated. The problem is that hot water requires the installation of an additional pump and all its accessories.
A large volume of a water heater in the case when the purchase of a boiler is needed for heating rooms with a large cubic capacity. And to place a dimensional device even in large rooms is still a concern.
Connecting the electric network of the heating element. In order for the water heater to work without interruption, it must be provided with a separate autonomous energy source.

If the problems are eliminated or they did not arise at all before, then you can proceed to installation and commissioning.

The temperature of the water inside the device is monitored and monitored through a mounted thermometer. Usually it is not included as an accessory in the kit, but it can be purchased at any hardware store.

Heating storage tank equipment

To put the heat accumulator in its rightful place, you must first prepare the site. Since the unit weighs so much, the floor covering must be strong and perfectly level to support the weight. In this case, it is equipped with an additional foundation or a new concrete screed.

The ideal option would be to equip a separate area for a weighty device. Thus, the housing does not touch the concrete and does not pressurize it. In addition, it significantly reduces the number of heat losses.

You can buy a model equipped with special legs. Then, instead of a platform, a layer of heat-insulating material should be laid on that area under the floor.

Installation and implementation follow step-by-step instructions:

1. First you should check how evenly the boiler is located in its place. It should be either strictly horizontally or vertically. In no case are even the smallest inclinations allowed.
2. Then comes the most crucial moment - connection. For high-quality operation, the pipes of the system and the boiler itself must have the same diameter in order to avoid excessive hydraulic resistance during testing and operation in the future.
3. Provided that the room is not equipped with radiators and other heating elements, the body of the water heater should be wrapped with a layer of thermal insulation.
4. Now the boiler can be connected to the hot water pipes. Then it will not only heat the room, but also provide water for household and domestic needs.

The final step is always checking the nodes and connections. The owner should start the whole system. For half a month, you will have to note the temperature regime maintained in the pipes and the boiler itself, after disconnecting the boiler from the network.

Any electrical equipment requires additional maintenance. With proper operation and inspection, the device will provide reliable service for many years. To do this, it is enough to follow all the recommendations that the manufacturers give in the instructions.

The procedures begin immediately from the moment of purchase. And the very first is the purchase of a model with dry heating elements. Their advantages are that scale settles inside the elements much more slowly (and there are much more impurities and salts in hot water). An additional measure is the filling of the unit with pre-filtered water into the storage tank.

There are a number of other measures to protect the heater:

Inspect the integrity of the structure every 30 days.
Monitor the temperature during working hours. This applies to both the boiler and the boiler, especially in late autumn and winter. Under ideal conditions, the difference between them is no more than 15%.
Replace gaskets in a timely manner. Then the heating system will work well and heat the house efficiently.
Pay special attention to the control unit. His life and work depend on fluctuations in the electrical network, which is why it often breaks down. To avoid this, you need to additionally connect a stabilizer.

To clean the heating elements of the boiler, open it and pull it out. But before that, think about whether there will be enough strength and experience to put everything back together, and whether the manufacturer's warranty will remain.

DIY water heater

In plumbing and hardware stores, boilers are quite expensive, and not every family has the opportunity to buy one. Alternatively, it is advised to assemble the device yourself.

First you need to take a large steel container. It is important that its volume corresponds to the calculated one. In order to assemble the circuit, you need to purchase additional elements:

Tank . It would be wise to buy a stainless steel base and drill holes for the inlet and outlet pipes.
Coil . The ideal material is copper as it is the best heat conductor among metals.
Fasteners.

To provide the structure with thermal insulation, experts advise making a two-layer case. And in the space between the layers, the owners will place basalt or glass wool. The optimum thickness is 5 centimeters. Then the self-made construction will be no different from the finished one.

There are many ways to heat a house using unconventional methods. However, not all of them are sufficiently effective, although there are those that have proven their efficiency in practice. One of the most effective and repeatedly tested in real life option is the use of an electric water heater for heating.

At first glance, a non-standard design is distinguished by its relative ease of installation, as well as operational efficiency. Although this option is not without its drawbacks, it can be found in many domestic apartments.

Main characteristics of the device

The main task of any boiler is to heat water. This can be done in two ways:

gas burner;
electric heating elements.

The second method is more acceptable, since it is easy to install and does not require a lot of permits. You can use an electric water heater for heating with maximum efficiency after studying its design features:

the basic part in the boiler is the body, which has several layers. The inner cavity contains water and is regularly heated. The outer layer protects consumers from hot surfaces, and the tank protects from negative mechanical effects and reduces heat losses;
heating elements are an important part of heating through a water heater. They are located directly inside the cavity where the water enters. They are controlled by programmed automatics;
manufacturers increase the thermal insulation properties by laying out mineral wool between layers. Also, some models in this gap have a layer of expanded polystyrene.

There are varieties of boilers for a private house, which are flow-through devices. They are distinguished by the absence of a storage tank inside. The cavity in which the heating is carried out is a compact flask. Such priori have high power parameters (5-25 kW for heating elements), which are combined with small overall characteristics.

Water heating in them is carried out in 30-120 seconds, which, at high power, creates a significant load on the household power grid. When installing them, it is necessary to control all electrical wiring in the house.

What parameters are taken into account when choosing a storage device

Accumulative type

Since it will not be possible to form a high-quality heating system with a flow-type heater, a boiler for heating a private house with a storage tank and indirect heating is considered more acceptable. When choosing the first one, it is worth paying attention to the following criteria:

Machine power

The rate of heating of the coolant directly depends on it. It also affects electricity consumption. The bulk of household appliances have a power in the range of 1.5-5.0 kW. The following conditions are taken into account: 10 m2 must be heated by a boiler for heating of approximately 1 kW of power.

Water cavity volume

This parameter affects the amount of the formed volume of water. Most domestic boiler cavities include a 50-10 liter cavity. Industrial apparatuses traditionally use 300 liters. The larger it is, the more reliable the system will be.

It is advisable to select the branch pipe with water entry, located on the body, with a lower location, and the outlet pipe - at the upper point.

Many household branch pipes are equipped by manufacturers with a ¾ inch diameter. To mount heating, it is desirable to have openings up to 2 inches in the structure at the inlet and outlet.

In order not to create a boiler as a deliberately weak link, it is necessary to carefully select this element.

Small devices operate at full capacity, which makes them different from the overall counterparts, which start / stop when necessary, for example, when it is required to heat water.

Indirect heating boiler

The principle of operation of such a device largely coincides with a storage device, with the only exception that a serpentine tube is located inside, which is connected to the heating system.

The main source of heating the coolant is the boiler. Any boiler, no matter whether it is storage, instantaneous or indirect heating, is only an additional device.

For the correct and most efficient operation of the water heater, it is installed in front of the return flow into the boiler, as a result of which the heat from the hot water supply passes to the serpentine tube. All this in a complex provides an optimal mode of operation of the entire system.

In order to reduce energy consumption, but maintain high efficiency, when choosing a boiler, pay attention to the following parameters:

Tank volume from 150 liters

The area of contact of the coolant with the coil depends on this indicator. The larger this area, the faster it will warm up.

Heating element power

Direct dependence of the heating rate on the power of the device. The calculated indicator is 2 kilowatts for every 50 liters of water.

Thermal insulation of the tank

And although all modern models are equipped with internal tank insulation, there are still those that do not have insulation. Choose a device with a double wall, where a certain insulation material is laid.

Such water heaters are much more expensive than classic ones. On average, a 200 liter boiler will cost approximately 25,000 rubles. This is certainly much better than using a conventional water heater, but the high cost cannot be discounted either.

Installation of a water heater in the system

Connection diagram

Electric water heating boilers have better parameters than boilers, but the latter are sold at very small prices and are used in a narrowly targeted manner. The calculation of the system is not based on the nominal power. The main baseline indicator in such a situation is the heating agent heating time. Some models provide this value at the level of 20-30 minutes, and the average indicator exceeds an hour.

An electric heater for heating a house is allowed to be used for installation only if certain conditions are met:

the wiring must withstand peak continuous loads for a long time;
installation should be carried out in a dry, warm room, for which heat losses can be minimized;
the most effective coolant for this system is distilled water, not antifreeze, due to its high thermal conductivity;
when choosing a boiler, it is advisable to select models with closed heating elements, as this will reduce the formation of scale deposits on their surface and significantly extend the service life.

Practice shows that boilers designed for heating the VEO brand have a high degree of efficiency. They are chosen according to their power.

Each device comes with instructions for use and installation. It must be carefully studied, as it contains important nuances of the installation process. The documentation also describes the available options for operation.

It is necessary to control the configuration of the pipelines and their further dilution. When distributing highways, it will be necessary to minimize or completely eliminate the appearance of knees. They reduce the performance of heating systems.

Suspension of radiators is carried out exclusively at the level in order to reduce hydraulic resistance and heat losses.

It is necessary to carry out thermal insulation work in the room in order to get rid of heat losses. This procedure will reduce the load on heating elements, as well as reduce electricity consumption. The installation requires timely maintenance. Preventive measures should be carried out in the warm season, while an experienced hydraulics specialist can be called. A cleaned and regulated apparatus works with a higher efficiency.

VIDEO: Heating system from a boiler

close ×

A boiler for heating water can become the basis of the heating system of a private house. This method has its advantages and disadvantages, but it copes well with this function. Installation of the system can be done by hand, taking into account the specifics of the event. It is important that boiler heating is affordable and simple enough to operate.

The boiler is an electric heating device for hot water supply. At its core, it is a container inside which a heat and electric heater (TEN) is located. To understand whether it is possible to heat a house with a boiler, it is necessary to understand the fundamental differences between a heating boiler and a heating device. In the first case, when the heat carrier (water) is heated, it naturally circulates inside the tank (boiler). Cold water enters from the top and exits from the bottom.

In the boiler, both openings (inlet and outlet) are on the same side, which prevents water from circulating independently through the heating system. In order for such a tank to perform functions similar to a heating boiler, it will be necessary to provide forced movement due to the circulation pump.

The efficiency of boiler heating is determined by the following factors:

Boiler power. It is deduced from the calculation of 0.1 kW for each 1 m² of the area of the room.
A pump that is properly selected to circulate water throughout the system at a sufficient speed.
The ramification of the heating system itself in the house.

A boiler for heating water of increased power (3-5kW) is quite capable of heating a small private house or summer cottage.

Currently, manufacturers of heating devices produce devices adapted for use in heating systems (boilers for heating). They have an increased volume of the tank, spaced inlet and outlet, enlarged their openings, and the power of heating elements increased to 7-10 kW.

Advantages and disadvantages

The main advantage of boilers for home heating is the simplicity of the system and low cost. For the arrangement of boiler heating, no special equipment is required, and the installation can be done independently.

The main disadvantage of boilers is their low power. Conventional household appliances are capable of heating only small houses and summer cottages, and in moderate frost outside. In addition, heating elements in the cold season must work in a continuous mode, which leads to their frequent failure. The heaters themselves have a low price, but the repair is quite laborious, which stops the heating system for a long time.

Criterias of choice

How to choose a boiler for home heating? To do this, you need to consider the following factors:

Design features. The best option for a heating boiler is to have the inlet at the top of the tank and the outlet at the bottom, with a diameter greater than 2 inches. When the inlet and outlet are located on one side, a pump is installed.
The power of the device. When using a boiler for heating water, it is necessary to select a device with a maximum power of 3.5-5 kW, which will make it possible to heat a room with an area of up to 50 m². A specialized heating boiler must have a power of at least 7-8 kW.
Volume of the tank. For heating, only an apparatus with a large tank is suitable, which will make it possible to operate the heating element in a gentle mode - the maximum power is set during initial heating (1-1.5 h) to form a coolant reserve, and then decreases. In household boilers, the volume of the tank should be about 70-120 liters, in specialized ones - more than 200 liters.
Materials used. During operation, the material of the tank undergoes significant corrosion.

When choosing a boiler, you should pay attention to the presence of a protective coating and the material used:

Glass porcelain or enamel coating protects well against corrosion only if it is intact. Under mechanical stress and sudden temperature changes, cracks and other damage appear, which creates a zone of active corrosion.
The tank body made of stainless steel or titanium is strong and durable, does not corrode. The main disadvantage is that such boilers are more expensive.

Varieties of devices

All boilers are divided into 2 main types:

Flow-through type. In such a device, there is only a small container, and the water is heated "for the passage". This is ensured by equipping the boilers with high-power heaters. This type can be used to heat small rooms, but it will require high power consumption and continuous operation of the heater.
Accumulative type. It is the most suitable for the heating system, because contains a tank in which the water is heated. This boiler has a certain inertness, i.e. heating of the room will start only when the entire volume of the tank is heated, which will take a certain time. Subsequently, due to the creation of a coolant reserve, it is possible to periodically turn off the power supply, which reduces its consumption.

When it comes to boilers, they usually mean electrical devices containing heating elements. However, there is another option when water heating is provided by gas - gas boilers. They are used less often, but are quite suitable in the presence of centralized gas supply. In this case, you can use the flow-through design of the apparatus.

Keep in mind that the use of gas boilers for home heating requires special permission from the relevant services and the installation of a gas meter. No authorization is required when using electrical household appliances.

Specifications

A typical design of a domestic boiler includes the following main elements:

The body of the apparatus. It is an external element that protects the working vessel from external influences.
Working tank or storage tank. It is located inside the case and separated from it by a heat-insulating layer. Depending on the model and purpose, the volume of the tank ranges from 10 to 450 liters. The best option for a private heating system is 150-250 liters.
A heating element. For boilers, depending on the volume of the tank, various designs of heating elements are used - rods, spirals, round models, etc. Their important characteristic is power. In boilers for water heating, heaters of 1-5 kW are installed, and in specialized heating boilers - 7-12 kW. When choosing a power, it is necessary to take into account the area of the heated room, the type of heating system and its branching, the height of the room and its thermal insulation, as well as external climatic conditions.
Connections. They provide the input of cold water from the water supply system and the output of the heated coolant into the heating system. Heating efficiency is determined by the rate of heat transfer, which largely depends on the diameter of the outlet. In heating boilers it is 1 / 2-2-3 / 4 "(10-20 mm), and in heating boilers it is 1.5-2" (30-48 mm). The larger the hole, the more efficiently the system works, but provided that the power of the heating element is sufficient.
Control devices. An indispensable element of modern devices is the temperature sensor for heating water in the storage tank. It is included in the heater's automatic power control circuit. When the required water temperature is reached, the heating element is turned off, and when it drops below the permissible level, it turns on. This allows you to maintain the required heat reserve in the tank during periodic operation of the heaters. In some models of devices it is possible to regulate the power of heating elements, which ensures optimal energy consumption.

The second important type of device is a network load monitoring relay. Prolonged overloads in the power supply network cause strong heating of the wiring, which creates a fire hazard. If too high loads appear, the relay turns off the heater.

When using boilers for heating, the following characteristics are also taken into account:

The water temperature in the storage tank must be maintained within 65-75 degrees.
The inertia of the system depends on the type of boiler and the power of the heating element. In tanks with volumes of 200-250 liters, it is 1-2 hours. In flow-through devices, water is heated in 0.5-2 minutes.
Household appliances must operate from a 220 V network, and the load must not exceed 25-40 A.

Installation of equipment

Arrangement of your own heating system using a boiler is carried out as follows:

Site selection and preparation for the installation of the storage tank. For this, a flat platform with a size of at least 1 × 1 m is being prepared with the possibility of unhindered access and maintenance. The amount of reinforcement depends on the volume and weight of the tank. For tanks over 200 liters, a separate concrete foundation, reinforced with reinforcement, must be erected. The best option is to form an individual platform with thermal insulation. This condition is not essential if there are mounting legs in the design.
Tank installation. Installation is carried out in strict accordance with the instructions. It is necessary to provide a rigid, stable and reliable fastening in an upright position. Tank inclinations to either side are not allowed.
Installation of a circulating pump. It is installed when used for heating water boilers. In specialized heating devices, the pump is installed only with a large length of pipes in the heating system.
Heating system connection. The outlet of the storage tank is connected to the inlet to the system or to the pump (if available), and the inlet to the heating outlet. To avoid the appearance of excessive hydrostatic resistance, it is necessary to fully match the dimensions of the outlet pipe of the tank and the inlet pipe of the system.
The connection to the water supply is provided through the inlet of the storage tank. Shut-off equipment must be installed to shut off the water as the tank is filled.
Power supply connection. The power supply to the boiler must be carried out through an individual panel, in which a circuit breaker and an RCD are installed.
Checking the tightness of the connections. It is produced without heating the water.

When installing a boiler for heating, the following recommendations should be taken into account:

If the storage tank is installed in a special compartment outside the heated room, then its body should be additionally insulated. For this, it is better to use roll insulation or foam.
After starting the system in operation, it is necessary to constantly monitor the heating temperature and the operation of automatic control within 10-15 days. This is necessary to clarify the correct installation and quality of equipment.
For simultaneous provision of hot water supply, it is recommended to provide an additional outlet for hot water at the outlet of the storage tank.
Heating with a boiler has a reduced pressure in the network, so the number of turns and branches in the system should be minimized.
To increase the durability and performance of the system, constant care is required - cleaning the tank from settling impurities and heating elements from scale.

Conclusion

For organizing your own heating system in the house, boilers are quite suitable. For small rooms and for summer cottages, a household appliance for heating water will be enough. When arranging heating in a larger house, it is better to use special boilers for heating. Boiler systems are characterized by ease of use and low cost, which makes them popular.

Good heating is one of the most important factors that distinguish a comfortable home from a home in which a person cannot feel comfortable. Today there are many traditional heating systems that can be used to heat a country house of any size. One of the most popular systems is gas heating. Natural gas is considered one of the cheapest heat carriers in our country. But, unfortunately, gas pipelines are far from being stretched everywhere. Therefore, heating systems that use a different heat carrier - for example, hot water - are very popular. And the basis of such a system can be an ordinary boiler.

Distinctive features of the boiler for the heating system

As you know, a boiler is a closed vessel that has two openings. The first hole serves as an inlet for cold water, the second as an outlet for hot water. The boiler is powered by the electrical network. All boilers are divided into two groups - flow and storage. In the storage boiler, a certain amount of water is heated (the amount of water depends on the displacement of the boiler), in a flow-through boiler any amount of water can be heated, but this requires more electricity.

It must be said that using a boiler for heating is quite possible, moreover, today manufacturers produce boilers specially designed for heating water in the system. These boilers have two significant differences from those designed exclusively for heating water for domestic purposes - for example, for bathing or washing dishes.

Firstly, in such boilers, the cold water inlet is located at the bottom, and the hot water outlet is at the top. This arrangement of the holes is explained by the fact that when the water heats up, it rises, and therefore, the hottest water is located in the upper part of the boiler, and it is the use of such water that will make the heating system as efficient as possible.

Secondly, a boiler designed to heat water in a heating system has a large hole diameter. If you look at factory-made boilers, you can see that both the cold water inlet and the hot water outlet are never less than 2 inches in diameter (about 4.8 cm).

If the boiler has both of these distinctive features, then it can be safely used as the basis for a heating system - it is designed for this. And the movement of water through the heating system itself is here due to the fact that cold and hot water have different densities, and cold water, entering the boiler, displaces hot water first upward, and then through a hole into the pipes of the system.

Using a boiler for a water supply system to heat a house

One of the frequently asked questions regarding the use of a boiler in a heating system is the following: is it possible to use a boiler, which is designed to simply heat domestic water, in the heating system. There is no definite answer to this question - it all depends on how branched the heating system itself is and what additional equipment is used in this case.

A boiler for a water supply system differs in that it has both holes (both the cold water inlet and the hot outlet) located at the bottom, and both of these holes are small in diameter (most often they are 0.5 inches or about 1.2 cm ).

This arrangement of holes excludes the possibility of water movement through the heating system on its own, since here cold water will not constantly "expel" hot water from the tank and force it to move through the pipes. But, in general, such a boiler can also be used in the heating system if it is supplemented with a circulation pump, which will be "responsible" for the movement of water through the heating system. The effectiveness of such a system depends on several factors:

on how powerful the boiler itself is. The suitable power is usually determined at the rate of 1 kW per 10 square meters of heated area.
on what power the circulation pump has
on how branched the heating system of the house is. It is best if it does not have many branches.

As for the type of boiler, here you can use both an instantaneous and a storage water heater.

So, heating a house with a boiler is not fiction at all, but a completely viable option for a heating system. The main thing when creating such a system is to accurately calculate the required boiler power, based on the size of the house. In some cases (for example, if the area of the house is large enough), the efficiency of the system can be increased by expanding the inlet and outlet for water, as well as by upgrading the boiler itself, allowing it to increase its capacity.
