Sanden GAUS 250 FQS Heat Pump. Ideal for average Households.
The Sanden Eco® system is the most energy efficient hot water heat pump currently available on the market. As such, when you buy a Sanden system, you receive the highest amount of Small-scale Technology Certificates (STCs) of any currently available hot water heat pump system. These STCs can be used to discount your purchase price. For more information, contact us.
Unlike other hot water heat pump systems, the Sanden Eco® system uses a smarter split system where the heat pump unit and stainless steel tank are installed separately. This allows easy on-site handling and installation, as well as options for the storage tank location, which can be up to 4 metres distance from the heat pump unit.
A heat pump is a device that uses a small amount of energy to move heat from one location to another, like an air conditioner in reverse.
It contains a fan that forces air through an evaporator that contains a refrigerant. The heat in the air passes through the evaporator and is absorbed by a natural refrigerant, R744 (CO2), which is ozone friendly and does not contribute to global warming.
The warm gaseous refrigerant is circulated in the system via a compressor. As it passes through the compressor, its pressure rises, as does its temperature. This hot refrigerant then passes through a heat exchanger to heat the water, which is finally pumped to the storage tank.
