Combination boilers are growing in popularity as a compact, cost efficient, and energy source for heat and hot water. Combination boilers provide the efficiencies of a condensing boiler and a tankless water heater in one appliance. This combination is more cost effective than separate boilers and water heaters and much more space efficient.
Most combination boilers follow a similar design where hot water heating is simply accomplished with a dedicated hot water heat exchanger built into the boiler cabinet. Triangle Tube’s Challenger Combination Boiler and Prestige Excellence models have innovative designs that differentiate them from their competition making them more efficient with a better hot water response.
The Challenger Combination Boiler features a unique two-in-one heat exchanger that provides both space heat and hot water. This innovative design makes the Challenger more compact and easier to install. Because the hot water is heated in the primary heat exchanger, there are fewer components, making it more reliable but more importantly it is much more efficient. With cold supply water flowing into the heat exchanger, the Challenger operates fully in the condensing mode, extracting the most heat possible from the natural gas or propane fuel.
The Prestige Excellence Combination Boiler combines Triangle Tube’s high efficiency stainless steel fire-tube heat exchanger with Triangle Tube’s tank-in-tank water heater. The unique tank-in-tank design stores 14 gallons of hot water and can provide 3 gpm of hot water on an ongoing basis. The stored supply provides the hot water response of a traditional water heater.
