SIH 20TE

High-temperature brine-to-water heat pump for indoor installation. 20 kW heat output.

Highly efficient for large areas.

The SIH 20TE is extremely high-performance with its 20 kW and designed for areas up to 450 sqm in both commercial and residential buildings. For heating, as well as domestic hot water preparation – with a flow temperature up to 70° C. It is therefore ideal for new apartment blocks or those undergoing renovation. Thanks to its high energy efficiency, it fulfils the standard requirements of the German federal energy efficiency ordinance (EnEV) and Renewable Energy Heat Act (EEWärmeG) and is also certified for the government market incentive program of the BAFA.

  • Extremely high-performance. designed for areas up to 450 m².
  • Fast installation. Variable connection options for brine and heating connections on the rear wall of the casing. Access for servicing from the front (no minimum clearance required on the sides).
  • Excellent efficiency values. Demand-based regulation via two compressors in the refrigeration circuit – if only one is required, the other switches off.
  • Always comfortable. Quick domestic hot water preparation via a flow temperature up to 70 °C – depending on the day consumption.
  • Future-orientated. Use of load-variable tariffs or self-produced PV-electricity possible: SmartGrid Ready.
  • Secure financial subsidies in a targeted way. Certified for the market incentive program of the BAFA.
  • Legal requirements fulfilled. Renewable Energy Heat Act (EEWärmeG), EnEV requirements, Energy efficiency class A++ (integrated system label).
