Solarfocus: new pellet elegance condensing boiler

Cluster-News: July 2018

Solarfocus developed the pelletelegance condensing boiler (10 - 24 kW). The condensing module, a stainless steel heat exchanger located at the rear of the boiler, removes heat from the boiler flue gas until a condensate is generated that can be drained away. Features of this technology include a very high efficiency (up to 104 %), reduced fuel costs and lower emissions. The condensing module is optional and can be installed separately.
In addition, Solarfocus developed the air heat pump vampair. Particular emphasis was placed on low-noise technology and efficiency.

Solarfocus: "Energy Genius" award for fresh water module

Cluster-News: November 2016

The fresh water module FWMautark from Solarfocus was awarded the "Energy Genius" prize. This product does not require electricity to operate. The generation of hot water is possible due to the pressure in the line and a cold water turbine that is directly connected to the pump. As a result, a constant hot water temperature is achieved even in time of fluctuating volumes of withdrawal and different temperature in the buffer storage.
