An inexhaustible heat source just outside your door.

The sun is our natural energy supplier. Take advantage of this free heat source for your house. It is located in the environmental heat in the air or is used as direct solar radiation. This source of energy is both free and inexhaustible from our point of view. The ROTEX HPSU (HeatPumpSolarUnit) is a heat pump installation which exploits the environmental heat available to supply heat to your house with maximum efficiency.

Best efficiency with solar 

Hooking up a solar thermal system is the most effective way to reach a higher overall system efficiency class. The ROTEX HPSU compact is already optimised for linking up with a solar thermal system – when you connect it to a ROTEX Solaris, will become your own personal ‚solar heater‘. The integral central heating backup and large storage volume will raise your system‘s energy efficiency ratings for both domestic hot water and space heating.

ROTEX new-build solutions.

Comfortable warmth in the winter, gentle cooling in heat pump the summer. The variable ROTEX HPSU compact reduces your heating costs to a minimum.

ROTEX solutions for modernisation with radiators. 

The ROTEX HPSUhitemp high temperature heat pump provides a heating water temperature of up to 80 °C.

With the new gas hybrid heat pump ROTEX HPU hybrid you get the benefits of two techniques. The HPU hybrid always automatically selects the best heating mode and can be integrated directly in a existing heating system if a gas Boiler is exchanged.
