Product description

ROTEX HPSU compact – high class efficiency

The ROTEX HPSU compact combines highly efficient heat pump technology with an innovative thermal store in the smallest of spaces. Electronic management of both heat pump and thermal store (ISM = Intelligent Store Management) maximises energy efficiency at the same time as heating and domestic hot water (DHW) convenience

The “Smart Grid Ready” label for all ROTEX HPSU compact heat pumps certifies their suitability for “power bias operation”. In order not to overload power grids, wind turbines are frequently shut down when more electricity than required is being generated. Storage is required to absorb these peaks in production.

Economical and quiet thanks to output modulating operation

The heat demand of a building varies very widely depending on weather conditions and utilisation patterns. The ROTEX HPSU compact 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.

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.


Application

The ideal solution for your new build

The amount of heating energy required by modern buildings is continually going down, resulting in lower flow temperatures. The HPSU compact low temperature heat pump is the ideal solution here, be it in conjunction with low temperature radiators or an underfloor heating system. The advantage of underfloor heating is that, due to the extremely large heating area, it can make do with a low surface temperature. Furthermore, it can even cool the rooms during summer.

Modernisation with twice the gain in convenience

Much the same applies to the modernisation of existing buildings as it does to new build: With the ROTEX HPSU compact heat pump, you'll be heating in winter and cooling in summer with highest levels of energy efficiency


Structure and funktion

Unadulterated enjoyment – every day

Hot and fresh water is indispensable for every household. Whether for showering, bathing, cooking or hand washing. Having hot water available in the desired volume and at the desired temperature is a significant constituent of our modern life. The fact that this water is also hygienic is, of course, a prerequisite. Conventional hot water heaters often fail to meet these requirements today. We have therefore placed special emphasis on water hygiene!

The hybrid heating centre – open to all energy types

The HPSU compact internal unit can furthermore be used as an efficient thermal store for additional heat sources. Apart from a solar thermal system, it can also be backed up for example by an oil boiler, gas boiler and pellet boilers or wood burning stoves with back boilers. If you do not install a solar thermal system immediately, one can be retrofitted quickly and easily at any time.


Energy efficiency class

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

Haus mit Wärmepumpe, Fußbodenheizung und Solarkollektoren

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. 

The combination with a thermal solar system is the most effective way to improve the efficiency class of the entire system.
