LA 25TU-2

High efficiency air-to-water heat pump for outdoor installation 25 kW heat output.

Outstanding performance.

The LA 25TU-2 is extremely powerful and highly efficient with its 25 kW heat output. Installed outdoors, this heat pump is ideal for renovated existing buildings or newly built apartment blocks with a heated living area of up to 550 sqm. Despite the impressive heat output, it is quiet during operation and also offers low operating costs and high seasonal performance factors.

  • Naturally quiet. Noise-optimised owls' wing fan. Encapsulated compressor chamber and free swinging compressor base plate for solid-borne sound insulation.
  • Power-regulated. Two compressor settings for optimal adjustment of the heat output to the building consumption.
  • Low operating costs. High seasonal performance factors through efficient operation.
  • Reliable. Operational reliability via sensor monitoring of the refrigeration circuit with demand-based defrosting. Integrated thermal energy metering
  • Easy to install. In cases of installation close to a wall in buildings which do not have a cellar, the pipework can be guided directly inside. Hydraulic connection of the heat pump optionally possible at the side or at the bottom.
  • Flexible 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.
