Product Description

Geothermal heat pump (also called ground source heat pump) is a central heating and cooling system that transfers heat from the ground. It uses the earth all the time, as a heat source in the winter do heating or hot water, or  a heat sink in the summer do cooling. This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems. Compared air to water heat pumps, geothermal heat pump work performance more stable.

Our innovative, high quality and intelligent controlled heat pumps have the characteristics of integrated design, modular installation, energy saving, easy maintenance and long life span. Every heat pump is manufactured and designed to optimize your intended uses. It get general tested as 36 hours seal test and water heating performance test, control system adjusted well before the shipment.

Heat pump performance (COP)

The performance of a heat pump at a set temperature condition is referred to as the coefficient of performance (COP). It is defined as the ratio of heat delivered by the heat pump and the electricity supplied to the compressor.

Higher COPs equate to lower operating costs. More higher COP, more energy saving.

COP is highly dependent on operating conditions, as to the ambient temperature condition, the COP data varies. This is Linsam heat pump COP chart, it at 7℃/35℃ COP of 4, which is produced according to standard of CE and EN14511.
