Top performance for larger areas.
The SI 14TU uses geothermal heat and offers 14 kW heat output for a heated area up to 300 sqm. This makes it ideal for newly built single family homes or apartment blocks, as well as for renovations. Little tip for the entire series: The integrated room temperature control Smart-RTC+ makes using geothermal heat even more efficient.
- 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.
