Natural Heat Sources

Free and natural heat sources for innovative heating solutions without negative impact.

Simultaneous heating and cooling

Simultaneous heating and cooling

Due to their double use and high economic efficiency, simultaneous heating and cooling systems are very attractive. COMBITHERM heat pumps have up to 5 different operating modes such as heating, cooling, heating with cooling, cooling with heating and free cooling. Depending on the requirements, the priority is set on heating or cooling mode. 

In case of free cooling, cold ambient air is used directly for hot water generation. No compressor operation is needed. As a result of double use and reduced current consumption, this typ of heat pump is the optimal, future-proof solution for your application.

Attractive Heat Sources

Constant availability of energy, independent of the year-time, characterize well-chosen heat sources. Especially for industrial applications, there should be no temperature or capacity fluctuations. Continuous and free heat sources are geothermal energy and river/wells water. The heat can be extracted from soil via geothermal probes, collectors etc. and in combination with heat pumps used for hot water generation. 
Moreover, wasted water or heat from sewage treatment plants or existing urban supply networks can be exploited for hot water generation. Chemical reactions such as corrosion can be avoided by using specially designed heat exchanger systems. For heat recovery, large heat pumps can be integrated into industrial processes. A particularly effective method is the heat recovery in ventilation systems.
