Qj Submersible Borehole Pump ISO9001 Certified
QJ Series Borehole Pump
Air to water heat pumps, which absorb heat from the outside air and then transfer it via the central heating system to provide hot water heating, radiator, or underfloor heating in an indoor space. UWO air to water heat pumps can be used for both heating and hot water systems, making them a versatile solution for building energy needs. Additionally, they have a long lifespan and require minimal maintenance, making them a reliable and low-maintenance option for heating and hot water systems.
