Installation of an electric boiler: installation of an electric heating boiler, a do -it -yourself connection diagram in a private house, how to connect it correctly to the mains

A great way to ensure efficient heating in your home and take advantage of modern technology is to install an electric boiler. Electric boilers are small, simple to install, and can be a more affordable option for heating your home than traditional boilers.

Electric boilers have several notable benefits, one of which is their ease of installation and connection. Without hiring an expert, you can install an electric heating boiler in your home if you have the necessary equipment and a rudimentary understanding of electrical work. To prevent any potential hazards, it is imperative to adhere to safety guidelines and make sure the connection is made correctly.

It’s important to know the electrical requirements and make sure the boiler is compatible with your home’s electrical system before connecting an electric boiler to the mains. To avoid overloading and guarantee the boiler operates safely, proper wiring and circuit protection are crucial. We’ll walk you through a do-it-yourself connection diagram in this post to ensure a safe and effective installation of your electric boiler.

Features of electric heating equipment

Most people agree that installing an electric heating boiler will maximize profits and that all types of electric heaters save between thirty and forty percent. They have excellent meanings that, in theory, can save a significant amount of heating costs. Usually, a lower power is given because of this economy, i.e. It is necessary to factor in the fact that, rather than the specified 100 watts, approximately 60 W of energy are needed to heat one square meter of space when calculating the heating system.

The opinions expressed in the preceding paragraph are incorrect in the majority of cases. Since all direct heating devices will be equal, it is inappropriate to compare them based solely on economy. The law of conservation of energy, which states that energy cannot appear out of nowhere and vanish, is the foundation for this assertion.

This implies that all of the energy produced will be converted to heat in electric heating devices. Naturally, there will be some losses associated with this phenomenon; however, some heat will inevitably escape into the atmosphere rather than seeping into the coolant. However, the device case’s insulation directly affects the amount of losses, not the kind of heating apparatus. Furthermore, the room where the boiler is located will be directly warmed by the heat that is released.

On the other hand, if we look at the issue, heating is meant to make up for thermal losses, the quantity of which is calculated:

• The quality of insulation of the building, completely independent of the effectiveness of the heating boiler;
• The temperature difference in the house and on the street, which also does not depend on the heating equipment used.

In summary, it is unquestionably true that the kind of heat source and the amount of thermal power needed to heat the building are unrelated, indicating that the much-discussed electrical device economy is nonexistent.

This only pertains to effectiveness, though, as every electrical device has unique operational characteristics.

1. Electric radiators. Such devices load the power grid evenly, so no requirements for wiring are presented.
2. Induction boilers. Such heating equipment is compact and reliable. The last quality is due to the fact that there is no heating element in the heat exchanger, and the power controller and coil are located outside, so the water does not have any effect on them. In addition, induction boilers can work with any coolant.
3. Electric boilers. They differ in the smallest size. Such boilers require a constant replacement of electrodes, since they eventually dissolve in water. Only water containing a certain amount of salts can be used as a coolant.
4. Tennaya boilers. The main problem of boilers with hets is the constant deposition of scale on the heating elements (this factor is irrelevant for closed heating contours in which the amount of salts is initially limited). In addition, these devices have quite large sizes.

Preparation of the place

It is essential to set up a circuit for the electric boiler’s heating circuit and electric network before installing the unit. The parameters of the pumping steering circulation pump should be synchronized with the pipe varieties and dimensions.

Consider the boiler’s electrical power when choosing the wire’s cross section to connect to the mains. A household network may be connected at 220 V for low-power devices up to 5 kW; however, a three-phase network at 380 V is necessary for more powerful units.

The installation location needs to be carefully chosen. Image sourced from Muzrain.ru

It is mandatory for equipment manufacturers to provide instructions on acceptable sizes and types of products, as well as recommended parameters for thermal and electrical circuits.

It is vital to consider installation markings in a responsible manner when researching the topic of installing an electric boiler correctly for residential heating.

The electric boiler needs to be firmly positioned horizontally. To do this, marking is done using the construction level and is also governed by the outcome, following the completion of equipment for installation parts.

Manufacturers also sell installations in the floor in addition to wall modifications. They are installed either on a heat-insulated surface that can support the weight of the installed equipment, or they are mounted on a standard support.

Eleking an electric boiler

The following components ought to be included in the strapping of electric heating boilers:

1. Circulation pump. This binding element ensures the movement of the coolant along the heating circuit, due to which heat transfer to heating devices is ensured.
2. Expansion tank. The key purpose of the expansion tank is to receive excessive excessive excessive overheating. The absence of a tank can lead to a rupture of pipes or damage to the elements of the heating system.
3. Safety valve. Using a safety valve, the excess of the coolant is dumped into the sewer. The valve works only in emergency situations – for example, when boiling water when the pump stops or when overflowing the tank. The pressure in which the valve is triggered is usually equal to the maximum pressure value in the system.
4. Automatic air vent. This element provides an independent output of the air from the contour of the heating system. In the absence of an air carrier, the circulation of the coolant will be difficult, and the system itself will make a lot of noise.
5. Manometer. The presence of a pressure gauge makes it possible to track the pressure level in the pipeline of the heating system. The manometer scale should be designed for at least 4 bar.

The expansion tank, airborne, and safety valve comprise the heating boiler’s safety group. In a private residence, installing an email boiler necessitates installing a security group as well.

Connection to the water supply boiler equipment

A drop in the amount of fluid in the circuit is an inevitable side effect of long-term (seasonal) heating operation.

This phenomenon is intended to be balanced by the water supply connection to the building’s heating system.

The water treatment devices are installed between two ball cranes that are typically fitted on the connecting pipeline. It might be a polyphosphate salt-filled filter. Chemically speaking, the filler keeps salt from building up on the boiler heating elements.

Please take note that the concentration of salts in the electrolysis solution—which involves both water treatment and the process of enriching the liquid salt—determines the electrode boiler’s efficiency.

The process of installing an electric boiler is not subject to oversight. Coordination of capacity allocation for equipment is only required if its consumption exceeds the parameters specified in the contract.

The modernization of the consumed kilowatt metering unit is determined by the optimization of electricity payment, which varies in cost throughout the day.

Set up a counter with two or more tariff gradations.

When temporary tariffing is used, the monthly cost of heating with an electric boiler is greatly decreased.

You can manually connect an electric boiler to a heating system, but if you want to make sure everything goes perfectly, you don’t trust your skills, or you don’t have enough time for independent work, go with installation companies that have a lot of experience. To ensure that your home’s heating system lasts as long as possible, only purchase products from reputable manufacturers.

Induction

The basis for the operation of induction models is the physical phenomenon known as "induction," which takes place when coils interact with one another. They rightfully occupy a leading position in the markets.

When discussing the benefits, the following should be mentioned:

• Very high efficiency, reaching 99% – thus all the electricity for which you have to pay is converted into heat
• Economical and effective in interaction with systems warm floor
• Can be simultaneously used for DHW (hot water supply)

The price of such equipment might be the only disadvantage. It is simple to install, but only a qualified expert can fix it if something goes wrong.

The choice of circulation pump

For the circulation pump, two parameters are important – pressure and performance. In most situations, it practically doesn’t matter how much pressure is applied. The minimum pressure of the weakest pumps is 2 meters, which is quite enough to ensure the normal operation of the heating system of any private house.

Two factors are crucial for the circulation pump: performance and pressure.

• Q = 0.86 * r / dt, where
• R is the total capacity of the radiators or the power of the boiler,
• DT – the difference in temperature in the supply and return circuit (in autonomous systems this value is 20 degrees).

Choosing an expansion tank for installation

The pump’s performance is more crucial, and it can be determined using the formula below: In the space between the tank cavities is a flexible membrane. The excess coolant enters the tank and compresses the membrane as its temperature rises.

You can use the easiest calculation to find the tank’s volume. It is sufficient to drain the coolant into any container whose volume is known in order to determine the total volume of coolant in the system. This value is subtracted by 10%, and the value that represents the tank’s volume is exactly that.

Advantages and disadvantages

The following are some advantages of electric boilers:

• complete noiselessness during work;
• There are no smells, the danger of fuel ignition and other threats;
• The boilers lend themselves to repair, and the costs of it are much less than on the restoration of units of a different type;
• The dimensions of the boilers are small and allow them to place them at any convenient point of the heating circuit;
• There is no need to withdraw a separate room;
• you do not need a chimney, the nodes of the passage through the walls or ceilings.

The following are some drawbacks of electric boats:

• The power of the unit of more than 5 kW requires the use of a 380 V connection, which is not easy to get;
• full dependence on electric networks;
• For connection, you need a separate line with high -quality wiring and protective shutdown machines;
• Efficiency of electrocots relatively low;
• Electricity tariffs are high and vary depending on the region.

The efficiency of the electric boilers is low, but induction models are an exception – their coefficient reaches 98 %.

Determination of the necessary parameters

It is necessary to familiarize yourself with all the technical specifications of the chosen electric boiler before installing it in a private residence.

Features of the electric boiler Navien EQB.

The following signs should be taken into consideration when purchasing an installation:

• number of contours;
• thermal power;
• Method of increasing the temperature of the coolant.

Any device running on the network at 220 or 380 V is suitable for installation in a private home; however, you should consider the number of phases brought into the house when selecting the unit.

The owner needs to be aware of the heated area in order to purchase the correct model of electric boiler. When selecting the device’s power, this is necessary. Most frequently, installations starting at 9 kW are purchased by all for home heating. The availability of unoccupied space in the home for installation determines which equipment—floor or wall—is chosen.

You should purchase a double-circuit installation if you require both a hot water supply and the maintenance of a cozy microclimate in the room during the cold months.

With its efficiency and control, installing an electric boiler in your house can completely transform your heating system. It is essential to know which way the mains should be connected when installing an electric heating boiler in a private residence. You can ensure safety and proper functionality by following the steps outlined in a do-it-yourself connection diagram. An electric boiler that will keep your house warm and toasty during the winter months can be installed successfully by following the instructions in the diagram and paying attention to local laws.

The location of the cauldron of the boiler

Every binding element needs to be put in a location that is clearly designated:

• The pump is mounted right in front of the boiler, in the area where the temperature of the coolant is minimal;
• The security group is installed behind the boiler, since it is at this point when the circulation stops the pressure that increases most of all;
• The expansion tank can be installed anywhere, but not closer to the double pressure of the pump pressure when installed before it, and not closer than eight times when installing it (if you do not comply with these requirements, the tank membrane will wear out too quickly).

All of the strapping components in boilers with het systems are frequently mounted within the equipment itself, creating a scaled-down replica of a complete boiler room. When installing an electric boiler with heating radiators, two ball valves are typically used in a circuit gap. This allows you to turn off the boiler without completely draining the coolant if needed.

Connection of the boiler to the mains

The use of DIY heating electric heating boiler is subject to several guidelines:

• You can connect any electrical devices with a power of not more than 3.5 kW to the outlet;
• Equipment with a capacity of up to 7 kW can be connected to the distribution shield (in this case, the cross -section of the wire is an important factor);

• With boilers with a capacity of over 8 kW, a special conversation – usually such boilers have a three -phase circuit, and the connection of a three -phase heating boiler to the mains is possible only if the latter is designed for 380 V;
• Also, electric boots with your own hands can be connected through a separate machine, and the machine operating the machine gun should only be one step exceeding the maximum operating current.

Instructions for the installation of the heater

All varieties of electric hot water boilers have mounting brackets or clamps that allow them to be fixed to the wall. Explaining the markings and clogging dowels is pointless, as any homeowner can do it.

As a point of reference. Both coal and universal electrical boilers are offered for sale in the floor that is covered in our other content.

How to select the ideal space and location for an electric boiler installation is another query. On the one hand, heat generators are allowed to be installed in any room according to regulatory documents. On the other hand, the location of large-power heat-sized devices is restricted by the rules for using electrical installations (PUE).

Even in the hallway, the wall version can be hung, but all communications must be disconnected there.

We offer the following general guidelines for properly installing an electric boiler in a private residence:

1. Given the large current in the circuit of working electric heaters, the devices are best installed in a separate technical room, for example, furnace or garage. The goal is to limit access to power electrical equipment and protect the devices from moisture exposure.
2. Tennovy mini-boiling is allowed to be placed in the kitchen or hallway. But take into account an important nuance: you will have to pull the main heating system and powerful power cable there. It is unlikely that these communications harmoniously fit into the interior, except to close the pipes into the wall.
3. When installing a heat generator on a wooden wall or other combatant partition, follow the requirements for hinged gas boilers. Under the back of the case adjacent to the tree, lay a sheet of roofing steel or basalt cardboard, as is made in the photo.
4. Provide the approach and access to the heater for the convenience of connection and maintenance. Install induction and electrode boilers in such a way that you place an expansion tank and pump nearby. Place the control cabinet at a height of 1.5-1.8 m from the floor.
   Recommended indentation to the boiler Unit "Potter Skat" specified in the instructions
5. Put the cables above the heating and sewer pipelines, so that they do not flood with water in the event of a breakthrough.
6. Heating pipes should not load with their weight the connecting fittings of the unit.

Crucial! Make sure the electric boiler housing is attached to the tire on the ground. Make a ground circuit on the street and lie in the boiler room if no one is there. Detailed instructions are provided below.

Usually used in conjunction with a primary solid fuel or gas boiler, an electric heat generator serves as a backup device. Thus, in order to ensure that the least amount of pipelines emerge, you must install heat generators and auxiliary equipment correctly. Plan ahead and create a diagram.

General recommendations

The issue of the premises’ requirements for the heat generator is causing concern for a lot of users. Regarding the location of the unit and whether a separate room is required, the current regulatory framework makes no mention of these matters. The installation of these kinds of water heaters should, nevertheless, follow the regulations governing the installation of electrical installations (PUE).

It is advised that you adhere to the following guidelines when installing the boiler if you want to make sure everything is done correctly and guarantee electrical safety in your home:

The best location for the unit is a combustion room or other technical space. This way, nobody living there—especially the kids—can unintentionally access electrical equipment. The Tennaya boilers from the factory manufacturing are an exception, as they can be installed in the kitchen;

Power cables should not be installed beneath water supply or heating pipes. In the event that preventing this is not an option, every precaution must be taken to shield the cable from water spills, such as encasing it in unique metal or plastic mounting boxes;

Don’t let the heating pipelines load the aggregate case with their weight when connecting the boiler to them. Pipes need to be fastened to the walls firmly;

Pay attention to the power cable’s vein section that corresponds to the current and power consumption. The ground circuit needs to be connected to the electric boiler housing.

It is important to note that different types of units require different installation strategies for electric boilers. Now, a house can be heated with these kinds of electrical installations:

In most cases, boilers with conventional heating components (heating plants) are like an actual microwave that is enclosed. The gadget controls the safety tools, automation, circulation pump, and, in certain models, the hot water heating element. This design greatly simplifies the installation process for electric boilers used in heating plants. Conversely, water heating components that need external strapping are electrode and induction heat generators.

Electric power supply in a three -phase network

An electric boiler’s three-phase network connection diagram is more intricate, but even a novice can understand it.

The following three phases need to be connected:

Take note of the following details:

1. With each water heater, a technical passport includes in the kit, which necessarily indicates the electrocottor strapping scheme recommended by the manufacturer. Guide only by this document in your case, t.To. Far from always provided on the Internet, examples can be suitable for your heating system.
2. Be sure to protect the boiler with an automatic switch and RCD. These devices will prevent the aggregate overload, short circuit and current leakage in the mains.
3. There must be a passage of the wiring.

Here is a visual project that shows how a boiler is used to provide electric heating in a two-story dacha:

Furthermore, we suggest viewing the following video, which provides a clear demonstration of how to connect an electric boiler at 380 V:

Electric heating is not very profitable, but it has many benefits, such as safe operation, reasonably priced equipment, and comfortable operation. The installation and connection of an electric boiler in a private home is the focus of this article. After reading our comprehensive guide, even the most skilled homeowner can install an electric boiler on their own.

Connection of the electric boiler to the heating system

Installing the unit itself and securely fastening it to the wall are the first steps. The heater boiler is suspended at least 1.5 meters above the ground; depending on how practical it is to strap someone up, an electrode or induction unit may be positioned below. The final two varieties of heat generators are installed in this instance vertically.

It is very easy to connect a tennium boiler with safety automation and a circulation pump to the heating system. The installation plan that outlines the need for strapping can be found below:

The pipelines are connected by ball valves, which are conveniently fitted with American, at the output nozzles. The reverse line is connected to a membrane expansion tank, which has a mud mesh filter installed on it. An additional ball crane is positioned in front of the mud to facilitate easy cleaning without emptying the entire system.

Take note. The location of the pipe to empty pipelines is not depicted in the diagram. This pipe typically collides with a return pipeline close to a heat generator, along with shut-off valves.

Electric shoes with electrode and induction types require a slightly more complicated installation process. The reason is that these units don’t have pumps that have to be used separately for the strapping. Furthermore, these boilers’ unique operating characteristics necessitate their inclusion in the security group scheme. It is made up of a safety valve, an automated air vent, and a pressure gauge. The latter is adjusted according to the operation’s position, as shown in the technical documentation that is included with the electric boiler. The figure displays the binding scheme:

Take note. The induction heat generator connection is depicted in the figure; adding an electric boiler will have the same appearance.

Frequently, homeowners combine solid fuel with an electric boiler. The operation of heating equipment is made more convenient by this, particularly at night. In the event that the dog in the топке прогорают, а некому новую закладку делать, то плектронагреватель поддерживает температуру в системе до самого утра. Furthermore, the electricity rate at night is substantially less than during the day. The joint binding scheme in this instance appears as follows:

Note: The diagram displays a heating boiler with an integrated pump in operation. The pump must be purchased and installed separately on the reverse line if an electrode or induction heater is required.

Pipes for electric boilers

Selecting the right pipes for heating is a crucial decision that always takes a lot of work. Nonetheless, there are no unique plumbing needs when installing an electric boiler in a private home; you can use the same metal, plastic, and metal-plastic pipes that are used to supply any heating system.

These details only become relevant when using polypropylene pipes:

1. Installation of an electric heating boiler with your own hands is possible only when using pipes reinforced with aluminum foil – this material compensates for the temperature expansion of the pipe when heated and reduces it several times. It is very important that the connection of the electric boiler to the heating system is performed by a specialist.
2. Long straight sections of the pipeline must be equipped with compensators. Compensators of any type are suitable-P-shaped, ring and bellows. These elements will prevent the bending of the pipes when the preheated coolant passes through them.
3. You can fix straight sections of the pipeline only with moving mounts, for example, sliding clamps.
4. When laying pipes in the walls of the strobes, it is necessary to do with a small margin – this will prevent the destruction of the seal of the strobe when expanding the pipeline.

Step -by -step instructions for installation

Installing an electric boiler in a private home doesn’t seem to be a difficult process that calls for expensive equipment. Many people manage without the assistance of specialists most of the time. Knowing the installation guidelines and the procedure itself is crucial.

Since an electric boiler will be the hub of the entire system and moving additional equipment may be a challenging process, the installation location must be decided upon in advance. It is required to make placement and surface preparations in light of the regulations governing the positioning of this kind of equipment. Recall that there shouldn’t be any combustible materials in this area. Wooden walls need to be sheathed with non-combustible material to prevent fires.

Canopies, dowels, and screws—everything you need for installation—are all included. However, it’s possible that the customized version will need an extra fastener that the supplier does not supply. Verify this beforehand.

Make dowel hole drillings. usually, with the exception of large systems, a diameter of no more than 10 mm. Fix and pill the boiler. Keep in mind that the fastening option may change based on the model. Some versions come with a mounting bar that you attach to the wall and then the unit just hangs on it.

The binding must be organized as the next step. Everything is also dependent on the boiler option. For instance, the monoblock case version of the electric boiler already has everything needed. Its layout includes systems to prevent overpressure, an expansion tank, and a circulation pump. To fill the system with water to the required pressure, all that needs to be done is run the heating line through the tap and to the feed and return nozzles. Such strapping should usually be sufficient if the house is small.

Only heating elements, coolant, and an automated temperature control system are included in the design of more powerful, but simpler to operate units. The latter might not exist.

In this scenario, purchasing a circulation pump, an expansion tank, threaded connections, and a security group—which consists of an air valve, a manometer, and a subversive valve—is required. The security group also provides protection against excessive pressure.

An illustration of a protection group

The plan calls for attaching the expansion tank and the hydrophoretor, to which, if the floor is not available, a special bracket is used for the fasteners. Additionally, a pump and a filter that stops solid fractions from moving through the system and potentially deactivate the pump are required, as is a system of pipes with security groups placed in the appropriate locations. Install the filter by following the arrow-pointing direction on it. Prior to the pump, the filter must be installed strictly. The circulation pump itself has an appropriate arrow as well. They have to point in the same direction.

It won’t be unnecessary to fix the pump with a clamp on a rigid support in the wall because it vibrates slightly during operation. The expansion tank is not essentially located in a closed system. However, many people with the security group make mistakes. This group should be positioned above all other system components because it has an air discharge valve from the system. Thus, you do not include the "delivery."

A security group is frequently mounted in the basement along with an electric boiler. Therefore, for a systematic air discharge, heating radiators on the first and second floors may continuously require the owner’s participation. We do, however, recall that the security group is outfitted with a subversive valve, meaning that it is strictly forbidden to place anything directly above the electrical equipment, which is the heating boiler. Even in the event of a valve malfunction, water shouldn’t reach electrical nodes.

Regarding the binding of the heating system, then there are several options, each of which can have both pluses and minuses. The option is selected based on the features of the room. And here, it is best to consult a specialist in advance. Ideal when the stream goes in one direction, bypassing all the premises of the house and returning through the reverse feed line to the boiler. Unfortunately, this is not always feasible, for example, when the house of a complex structure has two or more floors, and also has extensions that also need to be heated. In these cases, various ideas are used, up to additional circulation pumps and valve systems.

The installation of the locking valve system, which will cut off the entire system from the main nodes, is not a trivial step. As a result, you won’t have to empty the system of all of the coolant if the pump needs to be replaced, either when cleaning the filter or during boiler repair and maintenance. Prior to the liquid being supplied to the system, the heat carrier discharge valve to the sewer must also be provided.

In terms of the binding as a whole, everyone selects a reliable and inexpensive option here. Some people are primarily in need of metal pipes, while others are passionate about metalloplasty because of how simple it is to install. The construction of private homes is where the term "soldering" is most frequently used. PPR-S pipes with a cross section of 25–32 mm (no longer needing to be taken further) and fiberglass reinforcement for high temperatures are soldered using fittings into a monolithic system with the fewest possible threaded connections.

They also choose the radiators at their own discretion. Aluminum radiators are a good option for a regular home where the heating system’s pressure does not go above 1.5 atm and they are reasonably priced.

How to choose the right power

One crucial decision to make is the heating boiler’s power selection. Making the correct decision will guarantee that the room remains at a constant temperature regardless of external factors. When calculations are done correctly, rapid air warming in a cooled room and uniform room heating are ensured.

There are two ways to calculate power:

1. Based on the area of heated rooms;
2. Based on the volume of the heated room.

Calculation on the area

The basic value that can be used to heat a 10 m2 room is used to calculate power. This choice is highly arbitrary because the climate zone and other variables are not taken into consideration. Conditionally speaking, it is thought that 1 kW is needed to heat the area’s premises.

That is to say, if a 50 m2 house is built, equipment with a 3.5–7 kW capacity will be needed.

Additional calculations are accepted with the modification of these moments if we consider the height of the ceilings and the thermal insulation of the walls. These modifications are frequently seen in experiments across all climate zones. There are numerous calculation methods. One of them is predicated on applying the s*k*100 formula. Where:

• S is the area of the heated room;
• K is the coefficient of heat loss, which changes depending on the minimum indicators of air temperature. For the basic indicator, K = 0.7, used for the climatic zone, where the minimum temperature threshold is not lower than -100C.
• If the minimum threshold is lower, then the coefficient increases by 0.2 at each threshold of 50s.

Standard rooms are used to calculate this formula. This calculation is inappropriate if double-glazed windows are installed, extra thermal insulation is used in the room in a layer greater than 150 mm, the living quarters are raised to a height of 2.7 m and above, and the heated attic is not used for the roof’s heat insulation.

Calculation by the volume of the room

When accounting for the heat loss coefficient, this method enables you to calculate the power of heating equipment based on the volume of the heated room. The following fundamental variables determine the coefficient:

• Brick walls with improved thermal insulation, 2 -chamber double -glazed windows are used in the windows, the roof is mounted from heat -insulating materials. Coefficient from 0.6 to 0.9.

• Brick walls of double masonry. Roof and windows are standard. From 1 to 1.9.

• Reduced thermal insulation of the wall. From 2 to 2.9.

• Wooden walls or walls like sandwich panels. From 3 to 4.

Using these indications, the formula v*k*t/860 can be applied, where:

1. V is the volume of the heated room;
2. K – coefficient;
3. T is the temperature difference of the room and street.

50 m³ with walls that have less thermal insulation. While the air temperature in the room is preferred by the residents to be +250C, the lower temperature threshold is -100C. That is, 350C is the difference in temperature.

50 * 2 * 35 * 860 = 4 kW (smaller rounding applied).

Although this number is high, it is perfect in the event of extended frosts because it will maintain a comfortable indoor temperature. Not all possible sources of heat are considered. This moment is not included in the computation if the unit is also meant to heat water for household uses (shower, dishwashing).

Water heating safety

For electrical equipment to operate continuously and without interruption, it must be installed in the heating circuit of protective devices and devices.

They are displayed as follows, depending on whether they are mounted individually or congregate in a security group:

1. Automatic valve for the release of air from the water circuit (AVK).
2. A membrane type safety valve to discharge excess pressure from the system when the thermostat refuses or the occurrence of a blockage in the pipeline.
3. Manometer. The instrumental device serves for visual tracking the state of the working environment in the circuit. Иногда вместо манометра применяют комбинированное устройство, показывающее помимо давления и температуру теплоносителя.

Note for specialists: An expansion tank with a litter must be installed in the closed heating scheme in order to compensate for the linear expansion of the coolant system’s total volume.
