The future of waste water heat recovery

7th September 2020

Neil Macdonald, Technical Manager at the Heating and Hotwater Industry Council, takes a look at the consultation on the Future Homes Standard and what it is likely to mean for waste water heat recovery for showers.

In October 2019, the Ministry of Housing, Communities and Local Government (MHCLG) published a consultation on the Future Homes Standard, regarding changes to Part L of the Building Regulations for new dwellings.

It set out two options for uplifting energy efficiency standards, which were:

Option 1: ‘Future Homes Fabric’ would deliver a 20% reduction in carbon emissions, based on ‘very high’ fabric standards (typically triple glazing), a gas boiler, and a wastewater heat recovery system, as standard.

Option 2: ‘Fabric Plus Technology’ would deliver a 31% carbon emissions reduction based on ‘very high’ fabric standards (double, possibly triple glazing), a gas boiler, wastewater heat recovery system, and solar PV, as standard.

In each of the suggested specifications, wastewater heat recovery for showers (WWHRS) is included as part of the Part L compliance package.
