HPL 18S-TUW

High efficiency air-to-water heat pump for outdoor installation incl. domestic hot water preparation. 18 kW heat output. 300 l domestic hot water cylinder.

The powerful package for large homes.

Consisting of a high efficiency air-to-water heat pump (LA 18S-TU) with 18kW heat output for outdoor installation and the Hydro-Tower HWK 332Econ5S for heating and domestic hot water preparation. This package is ideal for large, newly built single family homes with a heated living area of up to 400m². The 300 l domestic hot water cylinder and 100 l buffer tank offers comfort for a 6-person home.

  • 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 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.
  • Low installation effort. Space-saving combination of 60 l buffer tank and 300 l domestic hot water cylinder.
  • Easy commissioning. Integrated heat pump manager and optimally coordinated hydraulic components.
  • Everything integrated. Three electronically controlled circulating pumps, safety valve (2/4/6kW) for heating support, flange heater with 1.5kW for thermal disinfection.
