Ground source heat pump technology implements transferring the low-temperature from earth's surface shallow water (river, lake, sea)and Soil that absorption of solar energy and geothermal energy,  to high-temperature by importing a little of electricity. Ground source heat pump can supply cooling, heating and domestic hot water.

DISMY ground source heat pump is a heating system which is designed for operation as brine/water heat pump. The heat pump extracts energy from the heat source medium at a low temperature level. This extracted energy is then transferred to the heating water at a higher level, enriched with the energy transferred by the compressor. Subject to the heat source temperature, the heating water can be heated up to a flow temperature of 55 .

A three-way valve built-inoptional have been integrated for diverting the flow either to the heating circuit or the DHW circuit. DHW is heated by pumping the heating water, which has been heated by the heat pump, through a heat exchanger into the DHW cylinder, where it transfers its energy to the DHW. DM2066 DHW thermostat can be used to start DHW function instant or by timing.

DDR series heat pump delivers heat up to a fixed temperature level. This is called fixed condensing. DDR series heat pump can be docked to an external unit with its own heating controls, for example, room thermostat for floor heating system or thermostatic valve for radiator.
