What are Water Source Heat Pumps?

A water source heat pump harnesses energy from water to supply you with heating and hot water for your home. Similarly to air source heat pumps, it extracts energy from a body of water near your property and converts it into heat.

Depending on the water sources available to you, there are two designs to choose from. A closed loop system offers less maintenance as it uses pipes filled with anti-freeze and is suitable if you live near a lake, loch or large pond.

Open loop systems require boreholes or straight pipes and can be used if you are located near a river, for example. As open loop systems are more exposed to the element, there is a risk of freezing. However, we will advise you on the system most suitable for your geographical location.

How do Water Source Heat Pumps work?

Typically the system consists of individual heat pump units connected by a loop through which the water source passes through. The closed loop version generates energy by circulating the antifreeze through the collector and thereby absorbing the heat energy from the water source.

The heat energy then passes through a compressor which increases the temperature. The higher temperature energy then flows on to your heating system (e.g. radiators, under floor heating) and you are ready to go with heating and hot water.

Is a Water Source Heat Pump right for me?

Consider the location of the water source you are intending to use. Remember that for maximum efficiency, the water source should be located as close to the house as possible. The water source can be further away if the pipe diameter is larger and placed in a downward direction.

To get the maximum heat and financial benefit, your home should be well-insulated. Also check with us beforehand whether it will be compatible with your current heating system. Please get in touch if you have any further questions regarding your property’s suitability, we will be happy to advise you.

Don’t forget you must have all the necessary permissions and paperwork completed prior to starting your heat pump installation. Despite these considerations, installing a water source heat pump is worth the paperwork.

What are the benefits of Water Source Heat Pumps?


Even though electricity is required, for every unit of electricity, you’ll be provided with two to four units of heat in return. Therefore, heat pumps are an energy efficient and sustainable heating solution.


Once installed they can have a lifespan of upwards of 50 years.


They are more efficient than ground and air source heat pumps as energy transfers better through water.


Water temperatures tend to be more stable throughout the year (between 7 and 12 degrees), which is higher than the average air and ground temperatures during winter.
