Reliable supply of heat on cold days

The Vitocal 300-G taps into the renewable heat stored in the ground or in groundwater. It is equally suitable for either new build or modernisation of detached and two-family houses.

Depending on the environment or energy available, the Vitocal 300-G is configured either as a brine/water heat pump for the utilisation of geothermal heat, or as a water/water heat pump for groundwater heat.
