Showersave has published a new report and executive summary exploring hot water cylinder sizing for domestic heat pump systems with showers.
With heat pumps expected to play a central role in the Future Homes Standard, Showersave is urging housebuilders to consider the benefits of Waste Water Heat Recovery Systems (WWHRS) and Instantaneous Electric Showers (IES). These technologies, the company says, can improve the performance of domestic hot water systems, reduce hot water demand, and cut household electricity demand for heating.
Developed in collaboration with Chris Martin – formerly of the Energy Monitoring Company – and Triton Showers, the report, titled Hot water cylinder sizing for domestic heat pump systems with showers: Accounting for Waste Water Heat Recovery and Instantaneous Electric Showers’, explores how WWHRS and IES can reduce hot water demand, how WWHRS can lower electricity consumption by pre-heating the incoming cold water, and why improved hot water cylinder-sizing models are needed to accurately reflect the impact of these technologies.
Tony Gordon, Managing Director at Showersave, said: “Our customers, including housebuilders and housing associations, face several challenges when installing heat pumps, particularly finding space for a hot water cylinder in homes that previously didn’t require one. This report demonstrates why the current guidance on hot water cylinder sizing must evolve to reflect new technologies such as WWHRS and IES.
“Working alongside Chris Martin and Triton Showers has allowed a detailed examination of how both housebuilders and homeowners can be supported to reduce energy bills, enhance hot water system performance and meet the Future Homes Standard.”
