Daikin Altherma heats up to 5 times more efficiently than a traditional heating system based on fossil fuels or electricity. By making use of the heat in the outside air, you use much less energy while still enjoying a stable and pleasant level of comfort.

Heat pumps use the reverse cycle of a refrigeration plant to heat water. In effect, it transfers heat from a source such as air which is sucked over the condenser by means of an electric fan.

A Green Geyser works by transferring heat – not by converting electrical energy in to heat. It removes the energy from the warm air in the environment. This energy is converted and used to super heat your water which is then stored in the insulated storage vessel. A small amount of electricity is required to operate the compressor. The quantity of heat delivered to the geyser is 4 times the quantity of electricity used.
