Case Study - St Gregory's RC School, Birmingham

Airtherm Engineering has completed another installation using Nova product serving two high efficiency wall hung Mikrofil Ethos 90kw condensing boilers at St Gregory's RC School in Birmingham.

Nova is a new breed of chimney system that offers a single solution for virtually all of today's combustion requirements. Nova is a true multi-fuel / multi-application product, whether being used to serve a solid fuel stove, vent the latest high efficiency condensing appliances or Biomass wood chip / pellet stove, Nova is the product of choice. With a diameter range covering thirteen sizes, Nova covers domestic and commercial applications. Manufactured from a 316L inner liner, 25mm high density insulated annulus and a grade 304 outer case, Nova is built to last. Unlike some of our competitors, Nova is designed with a rapid fit multi-barbed twist lock jointing system.

This not only offers a fast and simplistic installation method but also a durable and strong joint allowing a free-standing height of up to 3.0 metres to be support above the last support.

When used on appliances which product high levels of condensation, such as highly efficient condensing appliances, Nova can be retrofitted with a seal to allow both positive pressure and condensate resistance up to 200Pa, based on a maximum flue gas temperature of 200°C. Nova is available in thirteen sizes, ranging from 100mm to 600mm internal diameter. 

• Suitable for fully condensing applications
• Fully welded construction
• High level insulation
• High thermal resistance
• High speed twist lock jointing system to aid installation
• Without seals the product is suitable for multi fuel applications up to 450°C
