Air-to-water heat pump CHA Monoblock

Warm in winter, cool in summer and super quiet

Heat pumps are now installed in one of three new buildings and also an increasing number of renovated properties. We recognised the demand and developed a robust premium product designed for easy installation and long-term safe and economical operation.

It makes it easy to switch directly from oil or gas heating to a sustainable heat pump using the natural, environmentally friendly refrigerant R290 (propane). The practical monoblock design and an extensive range of accessories, high flow temperatures and peak efficiency make it all possible.

Overview of benefits

Efficient, environmentally friendly and extremely quiet

8 good reasons for you and your customers

Future-proof refrigerant R290 (propane)

R290 (propane) is an innovative and environmentally friendly refrigerant that is not harmful to the ozone layer and contributes little to the greenhouse effect. Due to its high availability, it is future-proof and economical in the long-term.

Extremely quiet for a peaceful neighbourhood

Numerous technical details, such as a slowly-rotating fan in owl-wing design, tracking geometry and installation of the components in a sound-insulating EPP core, ensure that noise from the heat pump disturbs neither operators nor neighbours.

Easy handling for rapid transportation

The compact dimensions and the convenient carrying device on the outdoor unit make setting up easier. The hydraulic connection can be established without additional accessories on the underside or rear - depending on the site conditions and customer requirements.

Top values for efficient heating and cooling

High efficiency makes this device eligible for state subsidies even in new buildings + low operating costs. The heat pump heats and cools with perfect modulation through the standard use of inverter technology. Agreeable warmth in winter and gentle cooling in summer via the underfloor heating.

Sturdiness and smooth operation

Designed for a long service life: With a robust housing and a UV-resistant powder coating, the heat pump copes with even the toughest environmental conditions. The raised base ensures problem-free operation in high snowfall regions.

Reliable failure protection and high power reserves

The demand-controlled 9 kW E heating element, which is included as standard, serves as a reliable power reserve for long periods of cold weather.

Directly online

With the WOLF Link home interface module and the Smartset portal, you can monitor your customers' systems via the internet at any time. This makes it easy to read the status of the system and optimise settings without costly travel.

The compact, all-in-one solution

The CHA Monoblock is also available as an attractive CHC heat pump centre solution. The ten modular variants of the CHC monoblock allow particularly space-saving and quick installation as well as a neat finish (including hot water and buffer cylinders).
