Description
The whole refrigeration circuit is placed in the outdoor unit, so little space is needed in the building. The unit dimensions are 1517 × 1800 × 885 mm for model 20/30 and 1764 × 1970 × 1000 mm for 43/60. The energy efficiency class is A+++ for low-temperature heating, and A+++ and A++ respectively for high-temperature heating. A supply temperature of up to 70 °C is suitable for existing buildings with radiator heating. Modulated operation removes cycling at full load, and the electronic expansion valve regulates the refrigerant flow. The manufacturer states that about five kilowatts of heat are obtained from one kilowatt of electricity. Active cooling is possible with suitable accessories. The pumps have SG Ready and the EHPA label, and online calculators are available for the seasonal coefficient and noise distances.
How to choose
First the heat output is compared. WWP LA 20/30-A R gives 11.6 kW and WWP LA 43/60-A R 22.67 kW at A7/W35, so the second model suits larger buildings, and its outdoor unit has larger dimensions. If there is no space for an outdoor unit, but groundwater is available or probes can be drilled, look at WWP W or WWP S.
