High subsidy level

The superior efficiency values of this environmentally friendly system mean it is eligible for the highest state subsidies.

Sustainable refrigerant

Efficient and quiet

Green & future-proof

The CHA Monoblock is environmentally friendly because it draws heat from the environment instead of using fossil fuels. It uses a refrigerant to do this. This WOLF solution is particularly future-proof thanks to the climate-friendly refrigerant R290. Read on

Extremely quiet

One of the unique selling points of the WOLF CHA Monoblock is just how quiet it is. The slowly rotating fan with blades that emulate owl wings, sophisticated guide vane geometry and a sound-absorbing EPP core keep sound pressure levels exceptionally low. Read on

Even more environmentally friendly power

The WOLF CHA Monoblock is equipped in compliance with the international EEBUS communication standard. This makes the heating system perfect for combining with other efficient energy systems.

 

For example, you can cover the electrical energy consumption of the heat pump with your own photovoltaic system to make the entire heating system even more environmentally friendly. 

 

You can increase the proportion of photovoltaic electricity you use locally even further by adding a storage battery. In this way, you can achieve maximum self-sufficiency in your home and operate the heat pump around the clock particularly cheaply using electricity produced on site.

SG Ready?

The SG Ready label is exclusively awarded to heat pumps with control technology that enables them to be integrated into a smart grid.

In summer, for example, the CHA Monoblock receives the “SG Ready” signal if excess power is available and the battery system is fully charged, and it then immediately initiates the cooling process.

The practical advantage is that the battery remains fully charged and you use your own electricity to cool your building directly and efficiently.
