Cascade boiler installation with the Schiedel Metaloterm® MF system.
The Metaloterm® MF system is a modular twin wall insulated flue/chimney system, made of stainless steel, with a sealing ring. Metaloterm® MF is a universal flue/chimney system which is suitable for both high and low temperatures, non-condensing and condensing applications with flue gasses in positive and negative pressure. It can resist a chimney fire.
Therefore the system is suited for a wide range of applications such as boilers, stoves and ovens. The product range also contains a wide variety of silencers. For Passive houses the Metaloterm assortment provides the Iso-block which can be combined with MF. The system can also be used for CHP applications, in this case a special VITON® sealing ring might be necessary. Due to the proven quality Metaloterm® MF has a 10 year guarantee.

Bunhill 2 Energy Centre
BBC Maida Vale
Airtherm design, supply and install a wide range of efficient, high performance systems including flues & chimneys, natural ventilation & lighting, kitchen ventilation, air conditioning (comfort cooling), heat recovery & heat pumps and solar photovoltaic (PV) panels for commercial, industrial and private sectors. They use products of the highest quality, such as the Schiedel Metaloterm range and can boast experienced engineers with excellence in their field.
Falcon Flues are expert Schiedel chimney system installers. An MF flue system was specified to serve 2 No 1200 KW Hartley & Sugden forced draught boilers at the BBC Studios in Maida Vale due to the the existing flue liner within a freestanding concrete stack collapsing. 2 No 400mm ID stainless steel twin wall insulated flue systems were installed from the boilers through to outside the boiler room and then up the outside of the concrete stack for 15 metres.
Another project from Airtherm Flue Systems Limited, using the Metaloterm MF System in a recent project for Greggs. The Metaloterm® MF system is a modular twin wall insulated flue/chimney system, made of stainless steel, with a sealing ring. Metaloterm® MF is a universal flue/chimney system which is suitable for both high and low temperatures, non-condensing and condensing applications with flue gasses in positive and negative pressure.
