Benefits of geoTHERM The geoTHERM range of ground source heat pumps provides maximum comfort and efficiency, combined with simple installation, smooth operation and advanced diagnostics that have become synonymous with the Vaillant brand. Vaillant isn’t just taking heating technology forwards and upwards – it’s taking it downwards, too, to unearth heating solutions that combine maximum heat efficiency with simple installation. How does geoTHERM work? geoTHERM ground source heat pumps utilise energy stored in the ground, transfer it through a refrigerant cycle and convert it into heat that’s perfect for space heating and hot water production. As ever with Vaillant, this ingenious product has been designed to ensure that the installation can proceed as seamlessly as possible and provide efficient, reliable heating on a continuous basis once installed. One of the most reliable sources of renewable heat, the Vaillant ground source heat pump comes with free commissioning and our intelligent remotely monitored control to ensure continuous comfort and peace of mind. As environmental concerns grow and your heating costs rise, the geoTHERM range underlines Vaillant’s commitment to meeting ever-changing needs by giving you the fuel efficient solutions you’re looking for.

Vaillant isn’t just taking heating technology forwards and upwards – it’s taking it downwards too, to unearth heating solutions that combine maximum heat efficiency with simple installation.
It may take its energy source from within the ground, but the geoTHERM exclusive ground source heat pump range is taking home comfort to new heights delivering heating and cooling in one solution.
geoTHERM geoTHERM is the perfect solution for heating your home. geoTHERM can be connected to a suitable high performance hot water cylinder for domestic hot water (DHW) and to an underfloor heating or radiator system for space heating.
geoTHERM exclusive geoTHERM exclusive offers a complete solution to your home comfort providing heat in the winter, passive cooling in the summer and DHW throughout the year, all from a single unit. geoTHERM exclusive is equipped with a weather-compensated energy-balance control unit incorporating a 175 litre stainless steel DHW cylinder and a 4kW electric auxiliary (backup) heater.
The geoTHERM range of ground source heat pumps provides maximum comfort and efficiency, combined with simple installation, smooth operation and advanced diagnostics that have become synonymous with the Vaillant brand. geoTHERM can be used in residential and commercial properties. The geoTHERM products are complemented by a range of large output heat pumps designed for larger homes or commercial buildings which operate on a 3 phase electricity supply. geoTHERM key features and benefits: Range of nine different output models available - 6kW, 8kW, 10kW (powered by single phase electricity), 14kW, 17kW, 22kW, 30kW, 38kW and 46kW (powered by three phase electricity) Evaporator with injection system for increased heat transfer

geoTHERM
geoTHERM exclusive includes an integrated passive cooling function when used with an underfloor heating system. During the summer months the heat recovery process can be reversed. The excess heat in the living space is withdrawn via the underfloor heating system and then transferred to the ground.

geoTHERM ground source heat pump range
Will a ground source heat pump be suitable for your home?
geoTHERM can be connected to a suitable high performance hot water cylinder for domestic hot water and to an underfloor heating or radiator system for space heating. It is an excellent choice for many properties, especially those off the gas network, and provides exceptional all year round performance.
How the technology works Ground source heat pumps use energy stored in the ground and convert this to heat for heating or hot water production. Low temperature energy from the earth is passed through a CFC-free refrigerant cycle, which converts this energy to higher temperatures for use inside the home or workplace.
Throughout the geoTHERM range the process of heat generation is controlled and monitored by advanced sensors. Continuous pressure measurement in the refrigerant circuit, the heating system and the bore hole/ground loop collector in combination with an anti-freeze function provides optimal comfort. The range also includes larger heat pumps for bigger domestic properties.
When was the property built? I nsulation levels in new properties have constantly improved since 1995 and therefore have a great bearing on the output required from a ground source heat pump. Please note properties built pre-1970 may need a great deal of building fabric improvements to allow a ground source heat pump to work efficiently.
I s there a preference for a ground collector or bore hole? Domestic properties may require up to 400m2 of land for ground collectors to be laid in and for bore holes, adequate access is required for heavy plant and drilling machines. This needs to be considered. Is there suitable space within the home to house a ground source heat pump? Ground source heat pumps are floor standing and therefore may not be suitable to be placed in the same position as your current boiler.
