Triangle Tube - Condensing Boilers: Why are they more energy efficient? (Part 2)

Traditional boilers are constructed with cast iron heat exchangers.  These boilers must operate at higher temperatures to prevent condensation from forming on the heat exchanger.  This condensation will cause the heat exchanger to rust and fail.  Condensation will form on the heat exchanger when the water returning to the boiler is less than 140F.  The lower the water temperature, the more condensation will form.

Condensing boilers are designed to accept low return water temperatures.  When a boiler operates at lower temperature cycles the boiler is more energy efficient.  In addition, when the boiler condenses the efficiency gains can be 10% or more.  For more information on what causes these gains, click here.

Triangle Tube's condensing, modulating boilers feature unique stainless steel or aluminum and copper heat exchangers.  The Prestige boilers (AFUE 95%) feature a stainless steel fire tube heat exchanger that is self cleaning to minimize maintenance costs.  In addition there is very little pressure drop through the boiler, resulting in lower pump operating costs. 

The Challenger Solo boilers have a unique aluminum and copper heat exchanger.  The water travels in copper tubes through an aluminum heat exchanger block  This assures rapid and efficient heat transfer with the long life of copper water tubes.  The Challenger Combi boilers feature two water tubes, one for boiler water and one for domestic water.  This allows the Challenger to condense in domestic mode, which many combi boilers do not do, achieving extremely high efficiencies.

Both boilers operate on natural gas and propane.  For more information contact your factory trained installer today.
