We are always updating our Info Centre so why not register with us to keep up to date with the latest developments in regulations, white papers, best practise guidance and our general tips and expert advice on designing, installing and maintaing ventilation solutions for new and existing homes.

Best Practise Guidelines on Heat Recovery Ventilation

                              Heat Recovery Guidance MVHR

  • BRE undertook research where MVHR had been installed in new build properties
  • 10 homes were assessed in West London
  • The research project was 2 years in duration
  • The MVHR units were installed in dwellings that were built to level 6 of the Code for Sustainable Homes
  • 9/10 MVHR units had to be re-commissioned with changes also made to the room inlet air valves
  • 1/10 MVHR units had to be replaced with changes also made to sections of the ductwork and insulation

A full copy of the report can be accessed via the NHBC Foundation Website

As a result of the research findings and the increasing focus on Guaranteed Installed Performance in line with the current Building Regulations, the NHBC have published a Best Practise Guidance Note on Heat Recovery Ventilation.

Chapter 3.2 NHBC Guidelines on Heat Recovery

With focus on Design, Material Selection, Installation and Handover, the NHBC Guidelines on Heat Recovery Ventilation push further focus on Guaranteed Installed Performance and linking all parts of the chain to enable this to be achieved simply and effectively.

The document brings key aspects from the Domestic Ventilation Compliance Guide which was released as a secondary document to Part F of the Building Regulations in 2010 as well as introducing new requirements such as location of Heat Recovery Unit, Controls and maintenance aspects such as cleanable ducting.
