Titon Supports New NHBC Standards - January 2014

Leading ventilation manufacturer Titon has given its support to the new NHBC Standards for 2014 regarding mechanical ventilation with heat recovery (MVHR). The Standards are the technical manual for NHBC registered builders with sections covering the design, material specification and site work for each part of the build process, and came into effect for the UK’s house building industry on 1 January 2014.

The new technical guidance, "Chapter 3.2: Mechanical ventilation with heat recovery", covers issues including system design, correct specification and installation of ductwork, location of the fan unit and prevention of condensation. This new technical benchmark will come into effect for every NHBC registered home whose foundations are begun on or after 1 January 2014, and aims to ‘improve the quality of MVHR installations in all key areas’.

Commenting on the new Standards, Tyson Anderson, Titon’s Sales and Marketing Director, said: "It is good to see the NHBC addressing a number of the potential issues associated with MVHR installations. We’ve been pushing for these improvements for a long time, as MVHR improves the indoor air quality of dwellings when fitted correctly. Addressing aspects including system design, ductwork, fan unit location and building location optimise the operation of MVHR systems, which will in turn strengthen their reputation."

The NHBC has recognised that MVHR systems are sensitive to relatively minor installation defects, noting that following the appropriate standards is fundamental to the systems achieving satisfactory in-service performance. Attention was drawn not only to the onsite installation but, more importantly, the very beginning of the construction process – at the design stage.

Titon’s range of whole house MVHR units has been developed in-house and manufactured at the company’s UK factory. All Titon MVHR units are rigorously – and individually – tested under strict conditions to ensure they perform to a high standard. The current test method for MVHR in the UK is based on the European Standard BS EN 13141-6:2004 (to define the duct configurations) and 13141-7:2004, which covers the testing of heat recovery ventilation devices. Some of Titon’s MVHR units are even tested according to TÜV SÜD standards – including important elements of the Passivhaus testing regime, recognised throughout Europe for strict test criteria and commitment to quality. All Titon products also offer unique benefits throughout the supply chain, being highly efficient to specify, supply, fit and operate.
