About Heat-Fab

HeatFab, by Selkirk, has been a top choice of builders for over 20 years and is the industry leader in producing special gas vent pipe (commonly called AL29-4C). Special gas vent pipe is primarily used on tankless water heaters, gas boilers and steam generators. These "condensing" appliances are extremely corrosive and only a special type of piping system (AL29-4C) is designed to withstand the corrosive properties of these appliances.


Additionally, HeatFab has set out to offer solutions for stove and chimney pipe relining projects. Coming in the standard six, seven and eight inch diameters, HeatFab stove pipe is made from the finest grade stainless steel available and has made a dedication to offer quality venting products at a price everyone can love.


Lastly, HeatFab rigid chimney relining systems are used with solid fuel and older oil and gas equipment. If the lining inside your chimney has begun to deteriorate, or you have an older system with no liner, adding a rigid chimney liner by HeatFab can add years to the life of the chimney and keep your home and family safe.
