With its 20 kW, the SIH 20TE is extremely powerful and designed for areas of up to 450 m² in both commercial and residential buildings. Both for heating and hot water preparation - with a flow temperature of up to 70° C. It is therefore ideal for newly built or renovated apartment buildings. Thanks to its high energy efficiency, in addition to the usual EnEV requirements and EEWärmeG, it is also certified for the BAFA state market incentive program.

• Enormously powerful. Designed for areas up to 450 m².
• Quick to install. Variable connection options for the brine/heating connections on the rear panel of the appliance. Access for service work from the front - no minimum side clearance required.
• Excellent efficiency values. Demand-based control thanks to two compressors in the cooling circuit - if only one is needed, the other switches off.
• Always convenient. Rapid hot water preparation thanks to a flow temperature of up to 70 °C - depending on daily requirements.
• Future-oriented. Use of load-variable tariffs or self-generated PV electricity possible: SmartGrid Ready.
• Complies with legal requirements. EEWärmeG, EnEV requirements, energy efficiency class A++ (composite system label).
• Clever. Eligible for subsidies in existing buildings thanks to high efficiency. Can be used in new builds to comply with the Energy Saving Ordinance (EnEV) and the Renewable Energies Heat Act (EEWärmeG).
