Rayes Boilers unique design of an innovative 3-Pass Down-Draft System on average, use 50% less fuel to create steam or hot water for any application needs, in half the amount of time when compared to traditional boilers. Installing a Heat Exchanger to the compatible connection on the boiler, can also heat the domestic hot water for free. Along with its unique design feature our line of boilers are greener and more innovative when compared to other traditional boilers in the market today. Rayes Boilers complete combustion system exhaust only 9 PPM of CO while other boilers in the market emit an average of 300 PPM.
