P.C. Mckenzie Company is proud to represent the Patterson Kelley line of Commercial Condensing Boilers. Experience a boiler design that is cutting-edge quality with worry free maintenance. 60% smaller than the leading competition makes this commercial condensing boiler the best choice for an easy fit in just about any application.
Typically non-condensing boilers cost about a third of the cost of a condensing boiler. Principal-2 80˚F ( – Select Heating Coils for a 27˚C ) Leaving Water Temperature Proper heating coil selection is the most important element of designing a high-performance heating water system.
Condensing boilers can achieve greater efficiencies because they capture more heat from the exhaust gases than a conventional boiler. To do this, a condensing boiler has a larger heat exchange surface to enable it to transfer as much heat as possible from the boiler's burner into usable heat, thereby allowing less heat to escape as exhaust gases.
Condensing boilers will help save between 10% and 12% on your energy bill every year. Whilst the initial cost of a new condensing boiler can be a little high, in the long run, they are a wise investment that will pay off by reducing your energy bills and saving hundreds annually.
Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.

Condensing boilers achieve high efficiencies because they can recapture the latent energy from the moisture in the combustion gases when those gases condense. For condensing to occur, the boiler’s heat exchanger surface temperature must be
• Used in traditional systems to protect non-condensing boilers from low return water temperatures and low flow • Used in modern systems to protect low-mass, low-volume condensing boilers from: –Thermal Shock –Low or No Flow (Localized Boiling, Scaling) –Excessive Flow (Erosion)
Dec 16, 2013· Optimizing hot water systems with condensing boilers Selecting a condensing boiler has the potential for high efficiency gains, but understanding special considerations for these boilers could cost you if you design the way you have in the past.
Jan 22, 2020· It all comes down to the way that condensing boilers work. How condensing boilers work With a traditional boiler, fuel is burned to heat your water but a large portion of this is lost out of the flue.
Condensing boilers vs non-condensing boilers. Both combi and heat-only boilers can be either condensing or non-condensing. Building regulations now state that all new boilers installed in a domestic home should be high-efficiency condensing boilers, although exceptions do apply in rare cases.
