Water Source Heat Pumps

What is a Water Source Heat Pump?

Water source heat pumps convert heat energy from a source of water on your property, i.e., from a river or stream, into useful energy to heat your space and water in your home. They require electricity to operate, but produce more than they consume and generate far less carbon dioxide than gas heating systems.

Take a look at our video for a full explanation of how a Water Source Heat Pump works.

What Types of Water Source Heat Pumps are Available?

Water source heat pumps come in closed loop systems or open loop systems. Closed loop systems are slightly cheaper but require a bigger body of water than open loop systems. If you’re investigating water source heat pump installation in your property, get in touch with Real Power today for more information about our services.


The cost of installing a water source heat pump is approximately £9500. While they have a higher initial investment than other types of heat pumps, water source heat pumps can last for up to 50 years with good maintenance.

All above pricing is subject to price fluctuations and therefore we recommend that you contact Real

No, you do not need planning permission to install a water source heat pump at your property in England and Scotland. If you live in Wales or Northern Ireland, you will need to speak to your local authority directly and potentially submit a planning application. Water source heat pump installation falls under permitted development, as long as the property is not listed, on a world heritage site or in a conservation area.

Although you may not need planning permission, you may need to obtain a license for the installation of a water source heat pump, because open loop systems often affect the temperature of the surrounding water. Contact your local authority if you are unsure whether you are able to install a water heat pump system.

Water source heat pumps typically take a lot longer to install than air source heat pumps, as they require more planning and pipework. If you want an estimate for how long the installation of a water source heat pump will take in your property, get in touch with Real Power today.

Water source heat pumps are very efficient, between 300% – 600%, even during cold spells. The particular brand of heat pump you buy will impact the efficiency and lifespan of the heat pump. The efficiency and lifespan of the heat pump will impact how much you need to spend initially setting up the water heat pump system, and what the system costs to run on a daily basis.
