Condensing boiler system
Choosing a new boiler for your home is an important decision. Making a wise choice can help you cut your home’s heating bill substantially. But, what is the difference between a condensing and a non-condensing gas boiler? Which boiler is most efficient? And which one is right for your home?

Traditional vs. Condensing Gas Boilers
What is a Condensing Gas Boiler
Traditional gas boilers burn natural gas or propane to heat the water in a home heating system. These boilers are vented to the outside via a chimney flue or vent pipe. Traditional boilers typically operate at higher temperatures, which means that a portion of heat is vented to the outside during the combustion process. Depending upon its age and type, a traditional non-condensing boiler will typically be 80% to 85% efficient.
Condensing boilers, are extremely energy efficient because they are able to provide ample heat for a home heating system while operating at lower temperatures. The result of operating at these temperatures is that condensation happens within the venting system of these boilers. Condensation can be harmful to the heat exchangers of traditional boilers, but the heat exchangers of condensing boilers are designed to operate in this manner and are not harmed by the condensation process. Lower operating temperatures result in less energy consumption and keep more heat in the heating system. Good condensing boilers can attain energy efficiency of 90% or more.
To select the most appropriate boiler, the engineer must considered the following specifications: local code requirements, cost impact, emission regulations, floor space, fire tube condensing boiler...
