Triangle Tube Tank-in-Tank

Triangle Tube has been manufacturing energy efficient boilers and combi boilers for over 70 years. Their core technology is a “tank-in-tank” combi boiler design, a name coined by Triangle Tube at the beginning of the 1980’s to describe a new type of indirect water heater that is capable of operating at high temperatures and withstanding the negative impact of liming while achieving efficiencies of up to 90.0%† AFUE!

ductless.ca Inc. is pleased to announce that we sell and install Triangle Tube’s full range of residential and commercial boilers including the Instinct, Prestige and Challenger Series in both solo and combi configurations.
