Max. heat output

The maximum heat output generated by a heat pump is the amount of heat it can transfer from the outdoors into the heating system and/or domestic hot water.

The heat output is the most important spec of a heat pump. It directly determines its efficiency and ability to provide the required amount of heat. Note that this spec is shown for optimal operating conditions. Such conditions are rare, so the actual output heat is usually noticeably lower than the maximum; this must be taken into account when choosing. There are special formulas for calculating the optimal value of the maximum heat output, depending on the specific condition.

Heat output (~ 0 °C)

Heat output is the amount of heat generated by a heat pump at a source temperature (air or ground - see above) of about 0 °C. This indicator is more visual and closer to reality than the maximum heat output (see above), so it is often indicated in the characteristics as the main one.

The required heat output depends on the area and some features of the room, on the need for hot water and a number of other factors; for its calculation in special sources, you can find the appropriate formulas.

Max. cooling output

Maximum cooling output delivered by the pump.

The pump operates in the cooling mode removing excess heat from the room to the environment — it plays the role of an air conditioner. The required cooling capacity depends on the area of the building, the specs of its thermal insulation and some other factors; methods of its calculation can be found in special sources. Also note here that conventional heating equipment (radiators, underfloor heating) is not suitable for cooling, for this it is necessary to use special equipment (for example, fan coil units).

Power consumption (heating)

Electric power consumed by the heat pump when operating only for heat transfer, without the use of an additional heating element (if any, see below). The ratio of thermal power to power input determines the thermal coefficient COP (see below) and, accordingly, the overall efficiency of the unit. It also affects overall power consumption (and therefore electricity bills), as well as some power and connection requirements — for example, models powered by 230 V and with a power of more than 5 kW cannot work from an outlet and require a special connection to the mains.

EER

EER is the ratio of the heat pump's output cooling energy to the input electrical energy.

The higher this parameter, the more economical the device is and the higher its energy efficiency class when cooling. Each class has clear requirements for EER.

Electric heater

The power of the heating element installed in the device (if such a function is available).

It isan electric heater in the form of a tube with an incandescent filament inside. Such a heater plays an auxiliary role; it is used when the heat output of the pump itself is not enough — for example, with a significant drop in temperature outside. The main advantage of heating elements is that their efficiency does not depend on outdoor conditions. And the main disadvantage is the high energy consumption. If the heat pump can transfer much more heat energy than it consumes electricity, then the heat output of the heating element is approximately equal to the consumed one. That is why the specs indicate the power of the heating element in general, without specifying what it is about: the indicated figure corresponds to both the heating power and energy consumption. These parameters are similar to those of the heat pump itself; see above for more details.

Minimum operating temperature

The lowest ambient temperature (air or ground, see Heat source) at which a heat pump can safely and reasonably efficiently perform its functions. Efficiency at minimum temperature, of course, is noticeably reduced, but the device can still be used as a heat source.

The data on the minimum operating T allows you to evaluate the suitability of the pump for the cold season.

Max. water temperature

The highest temperature to which the pump can heat the coolant. It is worth noting that such indicators can be achieved at a fairly high temperature of air or ground. And since heat pumps are used during the cold season, the actual maximum temperature, usually, is less than theoretically achievable. Nevertheless, this parameter makes it possible to evaluate the capabilities of the unit or its suitability for certain tasks.

Compressor

The compressor is the main element, the "heart" of the unit: it circulates the coolant through the heat pump circuits and transfers heat from outdoors to the room. Knowing the name of the compressor, you can find detailed information about it and find out some features of the heat pump as a whole. Note that the name is usually indicated if the device uses a high-end compressor, often an inverter one.

— Inverter. The presence of a compressor with inverter power control in the heat pump. Models without an inverter have only two modes of operation — either on or off; and the set intensity of heating/cooling is provided by turning the compressor on and off for certain periods. In turn, the principle of inverter control is to smoothly change the compressor power, which avoids constant switching on and off. It provides many advantages: minimal wear, no power surges and unnecessary load on the electrical mains, as well as a comfortable (low and stable) noise level.
