Recoup Energy Solutions Ltd confirm sole-supplier agreement for WWHRS with Bovis Homes

This month sees Recoup WWHRS confirm their sole-supply agreement for Waste Water Heat Recovery systems for Showers (WWHRS) with National house-builder Bovis Homes.

Recoup who engaged with Bovis group technical and procurement teams in March 2017, have provided design and specification advice for WWHRS across a variety of Bovis’ standard house-types. Recoup designed and tabulated a number of WWHRS scenarios, to allow Bovis’ SAP and sustainability experts to simply and effectively model the various scenarios in SAP for both energy efficiency and cost-efficiency.

Recoup’s award winning Pipe+ HE is the highest scoring product in the SAP 2012 database, currently available, and is used by new-build house builders across the UK.

WWHRS is fast being recognised by new-build developers as one of the most cost-effective SAP-listed measures available. Used in conjunction with a Fabric-First approach, the inclusion of WWHRS can often mitigate the requirement for other more expensive and potentially more troublesome measures. It is common to see SAP uplift (% improvement of DER/TER) of around 5-7% when using specifying the Recoup Pipe+ HE, as System A. The table below shows an overview of the main SAP-listed measures used by UK house-builders.

As well as cost-effective compliance, WWHRS has the end-user benefit of reducing domestic hot water (DHW) costs for showering by around 50%. This is a potentially significant reduction of energy demand for any house-type. But in modern homes, where fabric efficiency is such that space-heating requirements are drastically reduced, DHW costs often dominate with showering forming around 57% of DHW demand.

Furthermore, WWHRS is completely passive with no moving/mechanical parts; no external energy requirements; no consumables or filters to change; no planned maintenance; and no end-user interaction. Just passive heat recovery with every shower.

This agreement with Bovis, is in addition to Recoups’ ongoing sole-supply agreement with the UK’s number one house builder, Barratt Developments PLC, who use the Recoup Pipe+ HE for both their David Wilson Homes and Barratt Homes portfolios throughout the UK.
