As the Future Homes Standard (FHS) 2025 approaches, housebuilders face the challenge of meeting stricter energy efficiency regulations. One simple yet powerful solution? Shower Waste Water Heat Recovery Systems (WWHRS).
Showersave, part of The Keystone Group, has released a new white paper, ‘Why shower waste water heat recovery is crucial for heat pump efficiency and Future Homes compliance,’ highlighting how WWHRS enhances heat pump performance, reduces energy consumption, and helps meet regulatory requirements.
Why shower WWHR Matters
With air source heat pumps (ASHP) becoming the standard for heating and hot water in new homes, many systems struggle to efficiently meet hot water demand. Oversizing heat pumps increases costs and electricity use, adding strain to the grid. The research from the Centre for Sustainable Technologies at Ulster University shows that integrating WWHRS with ASHPs can:
- Increase hot water capacity – No more cold water interruptions during consecutive showers.
- Lower running costs – Reducing hot water energy use by up to 55% and cutting electricity bills by £150-£200 annually for a typical household.
- Reduce material costs and save space – Smaller hot water cylinders mean more efficient home design.
- Enhance efficiency and recovery times – Fewer homeowner complaints and better performance.
- Ease strain on the electricity grid – Supporting net-zero goals by reducing peak demand.
A Smart Solution for Housebuilders
“Heat pumps are fantastic for space heating and work brilliantly but can be challenged with hot water demands in larger households,” says Tony Gordon, Managing Director at Showersave.
As the UK’s first WWHRS provider, Showersave has installed systems in over 200,000 homes across the UK and Europe. Recognised in SAP by BRE and certified as a Passive House Component, Showersave supports housebuilders in meeting Part L requirements while offering a low-maintenance, sustainable solution.
