Water Source Heat Pumps

Water Source Heat Pumps

Large scale water source heat pumps can deliver reliable, commercially viable heat, which is suitable for distribution through heat networks.   Due to technological advances, heat pumps are providing a stronger business case, along with lower overall carbon emissions and their profile has been further enhanced by consistent government support and funding.

The pumps extract heat from a water source, such as river water, boosting the temperature via a refrigeration cycle.   This hot water can be transported through district heating networks to provide low carbon heat and hot water.  The same systems can also produce simultaneous, low carbon cooling where applications allow, providing exceptional plant efficiencies and coefficient of performance.

We have been working with some of the UK’s largest developments to help produce feasibility studies for the implementation of large-scale water source heat pumps and have collaborated with the Department for Business, Energy and Industrial Strategy on advising heat pump suppliers on how to make their systems more viable.

Most water source heat pumps can utilise water from a range of sources including rivers, sea, mine water, lake and canals.

Business Benefits

Water source heat pumps which meet the Government’s efficiency criteria are eligible for the Renewable Heat Incentive (RHI), making their long-term business case more robust.  Because RHI pays for only the renewable heat generated, water source heat pumps are a particularly applicable technology, with some projects seeing an estimated return on investment in just 4-5 years.

Additionally, water source heat pumps can be the ideal solution for organisations and developments who need to comply with stringent planning conditions.  The pumps produce no harmful on-site emissions, making them suitable for densely populated areas.

Environmental Benefits

Well-designed water source heat pump systems are expected to see in excess of 4kW of heat generated for each kW of electricity use, making them one of the most environmentally friendly technologies available and a great option for meeting strict emissions guidelines. 

In addition to reducing carbon emissions, these systems emit no harmful on-site greenhouse gasses and compliance with the Environmental Agency standards ensures that there are no detrimental effects to the local ecology.
