Heating area

A very conditional parameter that slightly characterizes the purpose based on the size of the room. And depending on the height of the ceilings, layout, building design and equipment, actual values may differ significantly. However, this item represents the maximum recommended area of the room that the boiler can effectively heat. However, it is worth considering that different buildings have different thermal insulation properties and modern buildings are much “warmer” than 30-year-old and especially 50-year-old houses. Accordingly, this item is more of a reference nature and does not allow us to fully assess the actual heated area. There is a formula by which you can derive the maximum heating area, knowing the useful power of the boiler and the climatic conditions in which it will be used; For more information on this, see "Useful Power". In our case, the heating area is calculated using the formula “boiler power multiplied by 8”, which is approximately equivalent to use in houses that are several decades old.

Remote control unit

Remote control unit that allows you to control the boiler from another room. It can be connected both wired and wirelessly, often equipped with an electronic display to indicate operating modes, set temperature, emergency situations, etc. Many of these units are advanced devices with the ability to programme the operation of the boiler, for example, for a week; some models can be equipped with temperature sensors that automatically adjust the intensity of the boiler depending on the temperature in the room.

Heat output

It is the maximum useful power of the boiler.

The ability of the device to heat a room of a particular area directly depends on this parameter; by power, you can approximately determine the heating area, if this parameter is not indicated in the specs. The most general rule says that for a dwelling with a ceiling height of 2.5 – 3 m, at least 100 W of heat power is needed to heat 1 m2 of area. There are also more detailed calculation methods that take into account specific factors: the climatic zone, heat gain from the outside, design features of the heating system, etc.; they are described in detail in special sources. Also note that in dual-circuit boilers (see "Type"), part of the heat generated is used to heat water for the hot water supply; this must be taken into account when evaluating the output power.

It is believed that boilers with a power of more than 30 kW must be installed in separate rooms (boiler rooms).

Rated current

The current consumed by the electric boiler (see "Power source") during normal operation.

This parameter directly depends on the power. It is required primarily for organizing the connection: wiring and automation must safely deal with the current consumed by the unit.

Coolant min. T

The minimum operating temperature of the heat medium in the boiler system when operating in heating mode.

Mains water intake

The diameter of the pipe for connecting the pipe through which cold water is supplied to the boiler for heating and use in the hot water supply system.

Diameters are indicated in inches. It is allowed to connect a pipe of a different diameter through an adapter, but the best option is still a match in size. There are connection options 1/2", 3/4", 1" and 1 1/2".

Safety systems

Gas pressure drop. This protection system ensures that the boiler is switched off in the event of a critical drop in gas pressure, insufficient for the normal functioning of the burner. In the event of such a fall, the valve that supplies gas to the burner is closed and blocked. After the restoration of gas pressure, it also remains closed; it is necessary to open it and resume the gas supply manually.

Water overheating. A temperature sensor automatically turns off the boiler when the temperature of the water in the system is critically exceeded.

Flame loss. Flame loss protection is based on a sensor that monitors the combustion of gas and automatically stops its supply. It prevents the room from filling with gas and the possible tragic consequences of this.

Draft control. In boilers with an open combustion chamber, to maintain normal conditions in the room where such a boiler is installed, constant removal of products of combustion into the atmosphere is necessary. The lack of a normal draft in the chimney can lead to the accumulation of combustion products in the room. The draft protection system prevents this by automatically turning off the boiler when it detects the release of combustion products outside the chimney.

Power outage. Most modern boilers h...ave an electronic control system; in addition, many structural elements (pumps, valves, fans, etc.) are also powered by electricity. Thus, a power outage during the operation of the boiler will inevitably lead to an abnormal mode of operation, which is fraught with breakdowns and even accidents. To prevent such cases, a power outage protection system is installed, which completely stops the operation of the boiler in the event of a power outage. When the power supply is restored, the boiler needs to be restarted manually.

Water circulation failure. This protection system controls the normal movement of the water through the heating circuit. Water circulation failure can lead to overheating of some elements of the boiler and damage to it. To avoid this, if the circulation is disturbed, the system turns off the pump and shuts off the gas supply to the burner.

Frost protection. A system that controls the temperature in the heating circuit. Freezing of the liquid in the circuit disrupts the normal operation of the heating, which may require heating of the pipes and lead to system damage. To avoid this, when the water temperature drops below 5 °C, the burner is ignited, the circulation pump is activated, and the circuit warms up to a temperature of about 35 °C — thus preventing the formation of ice in the pipes.
