Ready-to-connect compact unit

with a robust frame construction made from zinc-plated steel and powder-coated side walls to ensure a long service life.

Sound-insulated casing

for extremely low-noise operation.

Operation at two output levels

reduces the number of startups, thus improving cost-effectiveness and increasing the service life.

Sound-insulating floor mat
System controller TopTronic® E

makes ecological, economical, reliable and smart heating easier than ever before.

Large stainless steel heat exchangers

ensure optimum heat transfer to the heating water, generate high water temperatures and provide excellent efficiency.

Removable side walls

ensure convenient access to all components for maintenance work.

Sound-optimised design

Extremely quiet running thanks to 3-bearing, sound-insulated and thermally separated construction.

Thermalia® twin (6.7 - 55.4)

Monoblock earth and ground water heat pump with a heat output of 12.3 –55.4 kW for blocks of flats.
Two output levels ensure optimum operation, higher efficiency and a long service life.

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 6,59, they generate more heat from the electrical energy input than any other heat pump technology.

Thermalia® generates flow temperatures of up to 62 °C, with the H model, temperatures can even reach 67 °C. This makes it suitable for operation with conventional radiators – which is important when refurbishing.

With a Hoval heat pump in conjunction with a Hoval solar plant, you can transform your house into a small power station that will cover the bulk of energy requirements using sustainable, ecological and clean energy sources. Using the air, earth and sun as energy suppliers is intelligent and worthwhile.
