Geothermal heat for the entire family.
The SI 11TU is a highly efficient brine-to-water heat pump with 11 kW heat output for indoor installation. This heat pump is the most efficient solution for newly built single family homes and apartment blocks, as well as renovations, with a heated living area of up to 250 sqm. Like the entire series, it can be extended extremely flexibly and adapted to special applications, such as for use with a heat source temperature up to –10 °C.
- Naturally quiet. Sound-optimised through insulated metal casing and double vibration-isolated compressor.
- Low operating costs. High seasonal performance factors thanks to economizer and sensor monitoring of the refrigeration circuit for high operational reliability and integrated thermal energy metering.
- Expansion options. Bivalent or bivalent-renewable operation, distribution systems with mixed and unmixed heating circuits (e.g. underfloor heating and radiators). Even more efficient room temperature control Smart-RTC+.
- Future-orientated. Use of load-variable tariffs or self-produced PV-electricity possible: SmartGrid Ready.
- Intelligent. Eligible for funding in existing buildings thanks to high efficiency. Suitable for use in new builds for compliance with the German federal energy efficiency ordinance (EnEV) and Renewable Energy Heat Act (EEWärmeG).
- Adjustable. Including for special applications, such as use with a heat source temperature up to –10 °C.
