Triangle Tube - Condensing Boilers: Why are they more energy efficient? (part 1)

Boilers have been used to heat homes for many decades in what are known as hydronic heating systems.  In the early days, steam was used to transfer heat from the boiler to the home.  As designs improved water boilers became the norm, providing a more reliable medium to bring the heat to the home.  In the last two decades, condensing boilers have emerged as a more efficient way to transfer heat to the water in the system.

Traditional boilers have heat exchangers made from cast iron.  Cast iron is an inexpensive material and can last many decades in the right conditions.  One of the keys to ensuring the long life of a cast iron boiler is to avoid condensation in the heat exchanger.  Condensation will cause cast iron heat exchangers to rust and deteriorate rather quickly.   This rust will cause the heat exchanger to leak, requiring a boiler replacement.

It is relatively easy to avoid condensation in the heat exchanger.  Heating experts simply design the system to return water to the boiler at a temperature greater than 140F.  At this temperature, the heat exchanger will not get cold enough to form condensation.  

Triangle Tube is committed to energy efficiency and only produces high efficiency, condensing boilers.  All Triangle Tube condensing and combination boilers feature corrosion resistant stainless steel or aluminum heat exchangers and have AFUE's over 90%.  In fact most Prestige models are rated at 95% AFUE.
