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 the Compact P GEO will your home be self-sufficient with renewable energy, and it is no longer necessary to use energy sources such as district heating, oil or gas for heating. Compact P GEO is an environmentally responsible choice for those who want to use renewable energy for heating of the home and at the same time use the benefits in the form of markedly lower heating bills and a good and healthy indoor climate.

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.

Top cover

To cover the ducting over the unit, Nilan offers a top cover in white-varnished aluzinc (RAL 9016).

Solar

Extra heat exchanger of 0.7 m² in the hot water tank, which can be connected to an approximately 3 m² solar heating system, or other heat sources.

CO2-sensor

With a CO₂-sensor installed, the ventilation speed can be pre-programmed with CTS 602 to run at a higher ventilation steps when CO₂ reaches high level in the extract air. CO₂-level is programmable.

Pollen filter F7

A pollen filter class F7 can be fitted in the unit. The pollen filter is fitted with the G4 plate filter.

EM-box

An EM-box allows heat recovery from the air from the range hood and thereby helps to heat the supply air. The EM-box is equipped with a steel filter which efficiently cleans the range hood air of fat particles and thereby protects the system.

Electrical heating surface incl. regulation

When you fit an electrical heating surface, you can raise the fresh air temperature to the desired level at any time. The electrical heating surface is supplied ready to fit into the fresh air duct and, for easy fitting, the device is pre-fitted with all the required sensors.

Water heating element incl. regulation (duct mounted)

The supply temperature can always be raised to the required level using a water heating element. The water heating element is designed to be built into the duct and must be connected to the primary heating supply. Supplied with two-way adjustment valve, temperature sensor and frost thermostat.

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.
