The push towards a carbon-neutral country means that sustainable heating and cooling solutions are gaining traction. One increasingly popular option is the water source heat pump system (WSHP), a highly efficient, low-carbon alternative to traditional heating methods.
What Is A Water Source Heat Pump System?
A water source heat pump takes the heat energy from a nearby body of water — such as a river, lake or borehole — and uses it to provide heating and cooling for any property. Unlike traditional systems, WSHPs utilise a renewable energy source.
Types Of Water Source Heat Pump Systems
Closed loop systems use a sealed network of pipes submerged in water containing water and antifreeze, which absorb heat from the surrounding water. These are particularly well suited to colder climates.
Open loop systems draw water directly from the source and pass it through a heat exchanger to extract thermal energy. They can be more efficient but require EA approval.
Pros And Cons
Pros: High energy efficiency, lower carbon emissions, suitable for a wide range of properties, long lifespan (15–25+ years), quiet operation.
Cons: Higher upfront installation costs, require access to a suitable water source, EA licensing requirements, ongoing maintenance.
