and super quiet.

WOLF CHA englisch

Nine convincing arguments for you and your customers

Future-proof and ultra-hygienic

Future-proof and ultra-hygienic R290 (propane)
R290 (propane)

As an innovative refrigerant, R290 (propane) 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. The high-feed temperature of up to 70 °C provides thermal legionella protection without activation of the electric heating element.

Extremely quiet

Extremely quiet
A considerate neighbour

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

Ease of handling

Ease of handling
Rapid transport

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

heating and cooling

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

Sturdiness and smooth operation

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 large power reserve

and large power reserve

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.

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).

Combination with PV - super fast and easy

Combination with PV
- super fast and easy

With EEBUS, it is now possible to integrate WOLF digital heating in an integrated energy management system. This means that power consumption can be optimised and the direct consumption of power, for example from PV systems, can be increased. You want to optimise the use of home-generated electricity with the help of advanced PV technology? The intelligent appliances from SMA and WOLF speak a common language and can easily be combined with each other via Plug&Play.
