The functionality is available in Part L2 (2013) England, Part L2 (2014) Wales, and Section 6 / 63 (2015) Scotland. WWHRS is not available in any DSM version of UK compliance. Modelling WWHRS under SBEM is similar to modelling under SAP ![SBEM 2013 WWHRS modeling screen](https://knowledge.recoup.co.uk/hs-fs/hubfs/SBEM%202013%20WWHRS%20modeling%20screen.png?width=613&height=378&name=SBEM%202013%20WWHRS%20modeling%20screen.png) WWHRS can be accessed in the UK NCM data wizard in the Showers tab. This tab defines: - Number of shower types (by using the add/ remove button to increment or decrement) - Whether the shower has a heat recovery system **WWHRS Present**? - Whether the shower is located over a bath (cubical otherwise) **Shower Over Bath**? - If heat recovery is present, a definition of it’s efficiency **Heat** **Recovery Efficiency** - Whether the shower is pumped (so electrical energy can be tracked **Uses Pump** - If the shower has a pump, a definition of pump power **Notional Pump Power (W)** - Lastly how many individual showers of that shower type are in the building **Units** Currently, WWHRS is not available in any DSM version of UK compliance. However, workarounds do exist and we have described these in [this article](https://knowledge.recoup.co.uk/how-do-you-model-wwhrs-in-dsm-ies-ve-tas-apache-hvac?hs_preview=qCqRyaDD-59825859549&hsLang=en) WWHRS (DWHR) is available on IES VE - This is implemented in their ApacheHVAC tool and a user can configure the system there [See article here:](https://knowledge.recoup.co.uk/wwhrs-modeling-in-apachehvac-tool?hsLang=en) The information in this knowledgebase article was taken from IES: [Full article from IES](https://help.iesve.com/ve2021/uk_ncm_system_data_wizard_2.htm?ms=QwIAAAAEAAAAAQAAAAAAAAAgAQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAEAEAQEVAQIB&q=d3docg%3D%3D&st=Mg%3D%3D&sct=MA%3D%3D&mw=NDE5) - [The Basics](https://knowledge.recoup.co.uk/the-basics?hsLang=en) - [Modelling](https://knowledge.recoup.co.uk/modelling?hsLang=en) - [Technical Specifications](https://knowledge.recoup.co.uk/technical-specifications?hsLang=en) - [Systems & Installation](https://knowledge.recoup.co.uk/systems-installation?hsLang=en#main-content) - [General](https://knowledge.recoup.co.uk/systems-installation?hsLang=en#general) - [Pipe HEX](https://knowledge.recoup.co.uk/systems-installation?hsLang=en#pipe-hex) - [Easyfit+](https://knowledge.recoup.co.uk/systems-installation?hsLang=en#easyfit) - [Drain+ Duo/HE/Compact](https://knowledge.recoup.co.uk/systems-installation?hsLang=en#drain-duo-he-compact) - [Case Studies](https://knowledge.recoup.co.uk/case-studies?hsLang=en#main-content) - [Residential](https://knowledge.recoup.co.uk/case-studies?hsLang=en#residential) - [Non-Residential](https://knowledge.recoup.co.uk/case-studies?hsLang=en#non-residential) - [Contacts, Supply & Sustainability](https://knowledge.recoup.co.uk/contacts-supply-sustainability?hsLang=en#main-content) - [Contacts and Supply](https://knowledge.recoup.co.uk/contacts-supply-sustainability?hsLang=en#contacts-and-supply) - [Sustainability](https://knowledge.recoup.co.uk/contacts-supply-sustainability?hsLang=en#sustainability) [![Chill listening crop-3](https://knowledge.recoup.co.uk/hs-fs/hubfs/Recoup%20Logo%20Email%20(RGB).png?width=107&height=24&name=Recoup%20Logo%20Email%20(RGB).png "Chill listening crop-3")](http://recoup.co.uk) Recoup Energy Solutions Ltd Copyright © 2026, Recoup Energy Solutions Ltd
