Altherma, the new home heating, sanitary hot water and cooling solution with high energy efficiency.

A heat pump is a refrigerant based system (like your refrigerator at home but in reverse). The system can absorb low grade heat from the air (air source), water (water source) or ground (ground source), and raise its temperature efficiently to be suitable for space heating and/or hot water.

A heat pump absorbs free energy (heat) from a low-temperature source (air, water or ground) and upgrades it to a higher temperature, via the refrigerant cycle. Heat pump efficiencies range from 3:1 to 5:1 (300-500%), i.e for each 1kW of electricity consumed between 3kW : 5kW of heat energy can be absorbed and transferred.

By contrast, conventional fossil fuel boilers produce less heat output, about 0.85kW for every kW consumed, therefore heat pumps are more cost effective, eco-friendly and use renewable energy for the greater good of our environment.
