The type of heat pump.

The nominal heat output of the heat pump.

Cooling capacity is measured in British Thermal Units (BTU). It is a measure of a cooling system's ability to remove thermal energy from an area, under standard conditions. The higher the BTU, the more powerful the AC, which means it will be able to cool a larger space.

Heating capacity is measured in British Thermal Units (BTU). It is a measure of a heating system's ability to add thermal energy to an area, under standard conditions. The higher the BTU, the more powerful the AC, which means it will be able to heat a larger space.

The maximum temperature of the hot water provided by the heat pump.

The maximum flow temperature. This is important to know if it will be used for underfloor heating or radiators.

Audible noise is the noise that a device produces while in operation. Reduced audible noise improves quality.

The maximum heating temperature.

The lowest temperature it can reach when the heat pump is operating in cooling mode.

This is an American (USA) label given to highly-efficient products.

Seasonal Energy Efficiency Ratio (SEER) is a measure of seasonal cooling efficiency for air conditioners and heat pumps. The higher the SEER, the more energy efficient the unit is.

Seasonal Energy Efficiency Ratio 2 (SEER2) is a rating for seasonal cooling efficiency. It is an updated version of SEER.

Coefficient of performance is a measure of speed and effectiveness for heat pumps that is analogous to thermal efficiency for power cycles. Higher the COP, higher the efficiency of the system.

Seasonal Coefficient of Performance (SCOP) is an efficiency measurement for heating. It is an annual average of the Coefficient of Performance (COP).

Heating Seasonal Performance Factor 2 (HSPF2) is an efficiency rating for heat pumps. It is an updated version of HSPF.

Whether it has built-in smart connectivity. Sometimes it is only included as an optional extra.

The device can connect to Wi-Fi.

It is compatible with Google Assistant, allowing you to use voice commands to control the device from other Google Assistant-compatible devices.

It is compatible with Apple's Siri voice assistant, allowing you to use voice commands to control the device from other Apple HomeKit-compatible devices.

It is compatible with Amazon’s Alexa voice assistant, allowing you to use voice commands to control the device from other Alexa-compatible devices.

This technology allows the users to use their smartphone as a remote control for the device.

Without a variable speed compressor it can only operate it two states, on or off. A variable speed compressor allows it to run at different levels, maximizing efficiency.

A zoning system allows you to set up different areas of the home (such as different rooms) and adjust the temperature in each one independently.
