TWIN-WALL FLUE SYSTEMS
Construction
Twinwall sectional lengths/fittings are double-walled with fully welded vertical seam joints. Twinwall also utilises options of four insulated/non-insulated annular variation options which are integrated into the external case to help provide a minimum required outer case temperature. The jointing of inner liner and external case is that one side shall remain free to expand and retract according to the operating conditions and flue gas temperature.
Diameter RANGE
This double-lined system is available as TF 25 (with a 25mm insulating gap) or TF 50 (with 50mm insulation). There are also 75mm and 100mm annuli available on request.

Atmospheric boilers
Atmospheric boilers take in air for combustion directly from the place in which they are located (unlike more modern boiler designs which take air in from the outside of the building through a tube).
Ovens & Bakery
Commercial bakery ovens are available in various types, each suited to specific production needs:
Biomass Heating System
Biomass heating systems generate heat from biomass. The systems may use direct combustion, gasification, combined heat and power (CHP), anaerobic digestion or aerobic digestion to produce heat.
Combined Heat & Power
Combined heat and power (CHP), also known as cogeneration, is a highly efficient power plant that generates heat and power simultaneously.
Commercial Ventilation
A1 Flue Systems is a UK specialist in commercial ventilation systems for buildings of all sizes, from small office blocks to schools, hospitals and large skyscrapers.
Condensing Boilers
Condensing boilers capture the exhaust condensation of the burning gas that would otherwise be wasted through the flue.
District Heating Systems
It used geothermal energy to provide heat for about 30 houses and started operation in the 14th century
Fan Dilution Systems
Fan dilution systems were originally developed in order to discharge the flue products from gas-fired appliances at a CO2 level of 1% or less
Chimneys Liners
Most commercial chimneys were constructed without a liner system, although some were originally built better than others given time they all tend to breakdown over the years.
