Compact P Geo
Specifications & Technical Data
Compact P GEO has the same features and benefits as the Compact P, but can also use the energy stored in the ground to heat your home.
With help from ground pipes Compact P GEO uses and exploits the energy stored in the ground to heat your home using underfloor heating or other heating solutions at low temperatures. The system has an integrated 3 kW (Compact JVP 3) or 6 kW (Compact P GEO 6) geothermal pump. Both have a variable compressor which can be regulated 1.5-3 kW 2-6 kW (liquid/water temperature of 0°/35°C). This means that the solution adapts the need for heatinh, thus ensuring low power consumption.
Compact P GEO solution can reduce your heating bill by up to 50%. For each kW of electricity the geothermal heat pump uses, you will get up to four kW back.

TECHNICAL DATA
Compact P GEO offers the same benefits and functions as Compact P, but additionally has an integrated geothermal pump, with connection to waterborne underfloor heating or low-temperature central-heating radiators. The heat pumps are available in two sizes: GEO 3 (0.5 – 3 kW) and GEO 6 (1 – 6 kW). The variable compressor makes Compact P GEO a far more efficient and energy-friendly solution than traditional heat pumps that often have compressors with a constant output. As the output is subject to variable regulation, the heat pump never uses more energy than necessary, which gives a very high SCOP. With GEO 3, a SCOP of 5.17 is achieved.
