Vaillant Heat Pumps Geotherm

Vaillant Geotherm Heat Pumps

Vaillant's latest innovation in domestic energy conservation will be launched in April 2008, underlying our commitment to develop effective renewable energy solutions.
Energy from the ground can be used by a heat pump to provide useful energy to heat the home. Ground source heat pumps offer excellent energy savings as up to 75% energy for heating can be extracted from the ground.

Clean and efficient use of free energy source to provide heating and hot water
Every 1kW used to run the heat pump generates approximately 4kW to heat the home
Low energy bills
Reduces use of fossil fuels
Reduces CO2 emissions
Grants available from the Low Carbon Buildings Programme

How a Heat Pump Works

A closed loop of pipe is installed in the ground and filled with glycol anti-freeze mixture
- The fluid is warmed by the latent heat in the ground to about 10-12°C and pumped to the heat pump where the heat is transferred to the closed pressurised compressor circuit in the heat pump
- The heat pump then provides warm water for the heating system - The ground source heat pump can also be used to provide hot water
