LI 20TES

Air-to-water heat pump for indoor installation. 20 kW heat output.

Heats large areas with minimal effort.

The LI 20TES has a heat output of 20 kW and is ideal for large single family homes with up to 450 sqm, yet still so compact that it is suitable for indoor installation. The integrated air circuit enables corner or wall installation with air ducts at the air intake and the air outlet side. As is typical for this series, the model can be expanded flexibly thanks to the universal design. Domestic hot water preparation, for example, and the combination with an oil or gas boiler.

  • Naturally quiet. Low-noise axial 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.
  • 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. Even more efficient room temperature control Smart-RTC+.
  • Flexible. The integrated air circuit enables corner or wall installation with air ducts at the air intake and the air outlet side.
  • Space-saving. Extremely compact design with installed pipe heater (2 / 4 / 6 kW).
