LA 6S-TU

High efficiency air-to-water heat pump for outdoor installation. 6 kW heat output.

Small, but powerful.

For lower heat consumption, there is the LA 6S-TU with 6 kW heat output. All advantages of the big sister model are offered in a significantly more compact casing that can be positioned unobtrusively in front of a wall in a space-saving way. The minimum distance from the house on the intake side is just 50 cm. This heat pump is ideal for newly built single family homes with a heated living area of up to 140 sqm. The universal design enables flexible expansion options. Domestic hot water preparation, for example, or in combination with an oil or gas boiler. Different heat distribution systems (radiators, underfloor heating, fan convectors) can also be connected here.

  • Naturally quiet. Noise-optimised owls' wing fan. Encapsulated compressor chamber and free swinging compressor base plate for solid-borne sound insulation.
  • Low operating costs. High seasonal performance factors thanks to electronic expansion valve and high-performance evaporator.
  • Minimal space requirement thanks to installation close to walls and compact dimensions – minimum clearance from the wall on the intake side 50 cm.
  • Individual design. Select your chosen colour from 1,625 RAL shades.
  • 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.
