London Regeneration Scheme Uses Polypipe Heat Recovery Systems

Paynes & Borthwick development in West Greenwich, London has been fitted with Polypipe Ventilation’s award winning Silavent Green Line HRX Mechanical Ventilation with Heat Recovery (MVHR) systems. 

The landmark riverside development by United House Developments has seen a sympathetic conversion and restoration of the existing warehouse buildings, which have retained their original unique facades, with the addition of a new 18 storey residential tower.  In total, Paynes & Borthwick now features 257 high specification one, two and three bedroom apartments and ten combined live/work based units. 

200 Silavent Green Line HRX MVHR units have been installed into the development; supported by Polypipe’s comprehensive range of Domus rigid ducting. MVHR systems are designed to provide warmed filtered fresh air to a property’s living areas, using the heat recovered from waste stale air extracted from the kitchen and bathroom.  To achieve this, the HRX uses a highly efficient counter-flow heat exchanger, cleverly reducing the need for additional heating.  It also prevents the build up of condensation and mould and improves indoor air quality by providing continuous balanced ventilation.  Manufactured in the UK, the system is 2010 Building Regulations compliant and SAP Appendix Q listed.

Compact in size and light in weight (11.5kg), the HRX units are suitable for installation in a cupboard, utility room or loft space.  They come with user instructions mounted directly onto the front of the unit, so residents can easily understand how to operate and maintain the system.

The HRX range is designed with numerous innovative features to make installing and commissioning the units much easier and quicker than alternative models on the market. Such features include the wiring centre which is mounted externally, so that electrical connections and controls can be accessed for installation and commissioning without the unit being dismantled.  This also prevents the internal electrics from being exposed to any moisture within the unit.  In addition, all units in the range are ‘ambidextrous’ so that the appliances can be fitted to the left or right hand side of the property regardless of the location of the external walls, avoiding the need for complex ‘cross over’ duct runs.

The HRX units efficiently drive the fresh filtered air around the properties through Domus rigid duct, which has been third party tested for end-to-end system performance.  Its exacting tolerances and wide range of accessories make for easy installation and unimpeded air flow.
