Heating and cooling over an extra-large area.
For people who need lots of space and power, the high-efficiency LA 18S-TU is also available as a reversible air-to-water heat pump with 18 kW heat output. This package is ideal for large, newly built single family homes or those requiring renovation with a heated living area of up to 400 sqm.
- 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.
- Regulated cooling. Reversible heat pump for heating and cooling. Prepared for dynamic cooling (fan convection) and silent cooling (floor/wall/ceiling areas). Intelligent dew point regulation via the heat pump manager (e.g. with Smart-RTC+).
- 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.
