Turning water into heat.
The WI 14TU with 14 kW heat output uses groundwater as a heat source. Installed indoors, this water-to-water heat pump is perfect for larger, newly built single family homes or those in need of renovation up to 300 sqm. Like the entire WI series, it is eligible for funding in new and existing buildings. And it fulfils all legal requirements of the German federal energy efficiency ordinance (EnEV) and Renewable Energy Heat Act (EEWärmeG).
- 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).
