Water to Water
In a water to water heat pump we use geothermal energy from the ground as a heat source to produce hot water rather than the air. The advantage of this is the ground temperature is stable throughout the year. The disadvantage is the high capital cost of the borehole or trench required. We can guide you in this area.
One of the world leading companies in Geothermal technology is ClimateMaster, and we are their UK distributor. They have a full range of water to water heat pumps.
