Condensing Boilers
High-efficiency condensing boilers achieve greater than 90 percent efficiencies by condensing water vapor in the exhaust gases and recovering its latent heat. R.F. MacDonald Co. has exclusive representation to the following high-efficiency Cleaver-Brooks and Camus models: ClearFire-CE, ClearFire-C and ClearFire-LC and Advantus, DynaFlame, Dynaforce, DynaMax and MicoFlame Series.
In 2019, Cleaver-Brooks’ CFC-E boiler was voted Most Valuable Product of the Year by Consulting-Specifying Engineer magazine, which has been monitoring the trade since 1952.
