Product description

ROTEX HPSU hitemp – Simple installation

The HPSUhitemp consists of an outdoor unit, indoor unit and a hygienic thermal store. You do not need a separate utility room for the HPSUhitemp. The compact outdoor unit means that the erection site can be flexible.


Economical and quiet by performance modulating operation

The heat demand of a building varies very widely depending on weather conditions and utilisation patterns. The ROTEX HPSU monobloc heat pump employs inverter technology, which operates the compressor variably. In other words, the output of the heat pump is continuously adjusted to meet the demand.


The ideal solution for modernisation of existing buildings.

The ROTEX HPSUhitemp sets completely new standards. Even at extremely low outdoor temperatures of -20 °C, it provides a heating water temperature (flow temperature) of up to 80 °C with no additional electric heating required, thus reducing the energy costs. Another advantage: Your existing radiators are easy to integrate in the new heating system.

Structure and function

On the sunny side - Today and tomorrow.

The thermal store of the ROTEX HybridCube is already equipped for solar energy utilisation. If you are not installing a solar system directly, it can retrofitted quickly and easily at any time. ROTEX thermal store technology ensures constant hygienic hot water.

Energy efficiency class

September 2015: Energy efficiency label now also for heating

The energy labels provide reliable efficiency classes. These labels will make it easier to compare individual heating products and decide which ones to buy.
