Thermalia® dual (55-140) Thermalia® dual H (35-90)


Monoblock earth and ground water heat pump with a heat output of 17,5–181.1 kW for larger buildings.

Two output levels ensure optimum operation, higher efficiency and a long service life. Extremely reliable operation thanks to the two separate cooling circuits.

The Thermalia® earth and ground water heat pumps extract valuable energy from the earth or from ground water. With a verified COP value of up to 6,07, they generate more heat from the electrical energy input than any other heat pump technology.

The Thermalia® heat pump range covers all fields of application, from a single family home to medium-sized residential, commercial or municipal buildings. In their standard design, the devices are capable of generating flow temperatures of 60 to 62 °C. The H design can even produce temperatures of up to 70 °C. All models are available with a passive cooling function.
