Gas-Fired Boilers - Code Compliance Brief | Building America …
Boilers are more commonly used in commercial construction than residential construction, but they may be more prevalent in residential construction in some areas of the country and in older homes. Boilers are typically between 75% and 96% efficient in the primary process of heating the water, but any un-insulated heating water piping will lower the overall efficiency of space heating.
