Product description

In the monoblock type heat pump, the refrigerant system is completely integrated in the external unit. Such a solution ensures, above all, good thermal insulation, space saving and quiet operation of the device. In addition, the compact design ensures easy installation and simple maintenance.
The new series of GROHOD Arctic heat pumps is characterised by the possibility of operation in a very wide range of external temperatures, it is also distinguished by a much quieter construction of the external unit. In


addition to the possibility of connecting up to 16 units via the MODBUS protocol, the Arctic series also allows the connection of up to 6 units in a cascade system. The unit is equipped with a USB port to update the software and save settings.

The new ComfortHome app for tablet and phone allows you to remotely control the flow and hot water temperatures, zone switching and electricity consumption.
