Roth ThermoTerra BF - high efficiency with thermal output based on need

The Roth ThermoTerra BF boasts an output of 1,25 to 5,95 kW for heating and passive cooling and a compact internal mechanism. The heat generator and integrated hot water tank are perfectly coordinated for optimum compatibility, resulting in a hygienic and space-saving system solution. The pump operates with input temperatures of up to 65 °C. The coolant circuit is located in the lower section of the heat pump, housed inside a removable multibox. This design insulates the compressor for virtually noiseless operation.

Roth ThermoTerra BF with thermal output based on need
Frequency-controlled heat pumps operate based on the precise needs of the user and the building, resulting in a significant increase in energy efficiency. Its compressor and the heat source and heating circulation pump automatically adapt their speed to requirements. The Roth ThermoTerra BF boasts an outstanding performance coefficient of 4,86. Operating costs are further reduced by the low start-up current requirements. The ThermoTerra BF heat pump is especially suited to apartment buildings as well as houses.

Each individual home in the building can be
