Water source heat pumps (WSHPs) offer a versatile, highly efficient alternative to fossil fuels, taking heat energy from a variety of water sources, such as the sea, lakes, large ponds or boreholes, to provide you with a reliable energy source for heating and hot water. They can also be used for cooling too.
A water source heat pump extracts latent heat from the sea, rivers and lakes, or an underground water source via a borehole. Water is pumped into the heat pump where the latent heat is used to compress a refrigerant in the majority of systems, known as a Closed Loop System. This compression increases the temperature of the refrigerant, which then transfers heat into the distribution system. In an Open Loop System, the water from the source is directly used in the heat pump. They can provide heating and hot water to both new and retrofit premises.
Whilst the concept is relatively straight forward, the design, installation, operation and maintenance of them is an extremely specialist area. We can work with you from the concept design and energy modelling stage through to the long-term asset management. As the size, connections and intricacies of these systems vary, water source heat pump costs can range from several thousand, to multi-million pound installations, but we will find the best option for your organisation.
