What is a water source heat pump?

Water source heat pumps extract thermal energy (heat) from water sources near your property and convert this into heating and hot water for your home. Water source heat pump systems are ideal for homeowners that have a suitable water source onsite, such as a lake, river or stream.

By adopting a water source heat pump system, there is the added advantage of consistent water temperatures, which in turn produces consistent hot water and heating, even in the coldest of temperatures. Pipework systems are also submerged underwater, so this makes water source heat pump systems a viable option for projects that are especially aesthetically sensitive and require minimal visual impact, during installation and once completed.

Water source heat pumps are designed to work in cold temperatures and are incredibly efficient. They do require electricity to operate, but 75% of the energy required is generated from the thermal energy extracted from a water source, with only 25% being required from electricity. This means that 75% of the energy you use will be from a renewable source, which will reduce your emissions and CO2 impact.

The advantages of using thermal energy from water:

  • Provides heating and hot water for your home
  • Perfect for properties that a local water source
  • Heat pumps can be housed indoors or inside outbuildings where required
  • Doesn’t require extensive digging or drilling for boreholes
  • Ideal for properties generating electricity from a hydropower
  • Quiet during operation
  • Minimal visual impact during and once completed
  • Works in cold outside temperatures
  • Compatible with radiators and underfloor heating
  • Minimal ongoing maintenance
  • No fuel deliveries or fuel stored onsite
  • Possible to benefit from Government incentives such as RHI payments

Is a water source heat pump suitable for my property?

Here are a few things to consider when looking into an water source heat pump system for your property:

  • Do you have a suitable water source on your property? It is important that a suitable water source can be accessed for the installation to be completed successfully. Rivers, streams, and lakes are all potential sources. Speak to a reputable installer who will be able to conduct a feasibility test and assess whether your local water source is suitable.
  • Is your home well insulated? Generating heating and hot water sustainably is only beneficial if you have improved the efficiency of your home. Each property is unique, but it is important to understand what other measures can be done to reduce heat being lost in your home. Looking at loft insulation and whether you have double glazing windows will be a good start, but consult a professional for further guidance on what is feasible for your home
  • Are you looking to replace a heating system, or for new build homes, is this the first heating system to be installed? Replacing an ageing heating system will deliver faster benefits due to the improvements in efficiency. However, for new build homes, it is worth discussing with your installer how your heat pump system will work throughout your home – this includes choosing underfloor heating or radiators, as well as suitable controls to operate it
