High temperature heat pump ROTEX HPSU hitemp

The 2-stage heat pump for modernisation achieves flow temperatures up to 80°C.

In old buildings, high flow temperatures are often required, which can not usually be generated efficiently with conventional low-temperature heat pumps. Therefore, special high-temperature heat pumps are used in these cases. Thanks to a second cooling circuit, the ROTEX high-temperature heat pump is ideally suited for heating modernization with existing radiators. The HPSU hitemp is economical and quiet in operation and the installation is fast, clean and space-saving.

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

Inverter LogoThe 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 HPSU hitemp 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.

Innovative heat storage concept - Hygienic, flexible and future-oriented

All ROTEX products with the ECH2O label are characterized by a unique heat storage principle. Particularly space-saving, with the highest warm water comfort and open for additional heat sources. The innovative heat storage concept is applied to the HPSU hitemp when you combine the heat pump with a HybridCube thermal store.

Energy efficiency class

Energy efficiency label for heating systems - safe in the knowledge it‘s ROTEX

All ROTEX products are tested and meet the criteria of the Ecodesign Directive. For both individual products and packaged solutions, energy labels are a reliable indicator of the precise efficiency class. Perfectly matched in terms of their individual components, our complete systems provide both maximum convenience and the highest safety standards.
