WI 18TU

High efficiency water-to-water heat pump for indoor installation. 18 kW heat output.

Heat large areas with groundwater.

With a heat output of 18 kW, the WI 18TU easily heats living areas up to 400 sqm. This enables energy efficient heating of large single family homes or semi-detached and terrace houses. Like all models in this series, it is also extremely flexible and can be adapted to bivalent or bivalent-renewable operation.

  • 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).
  • Always up-to-date.
