heat pump

The operation of the heat pump is regulated by a compact controller and the heart of the device is a high quality compressor guaranteeing many years of a fault-free operation.

Facts:

• for heating a house
• a compact unit ready for installation on the outside of the building
• heat power from 5.8 kW to 11.5 kW
• COP value from 4.25 to 4.55
• maximum temperature of DHW  55°C
• modern controller with a room regulating unit and a possibility to use it via Internet (optional) – fixed IP required
• higher efficiency thanks to an electronically controlled injection of the cooling liquid to the evaporator
• possibility to be connected to any exchanger of a working installation
• integrated circulating pump
• very quiet operation thanks to the use of the new generation fans
• very efficient automatic evaporator defrost system
• works well also in the temperature below -15ºC

Standard equipment of Maxi Air heat pumps:

• integrated outdoor unit
• Siemens controller
• built-in electric heaters (its power depending on the model)
• electronically controlled expansion valve (increases the efficiency and improves regulation and pump operation parameters)
