Natural Gas Boilers
Natural gas boilers can be used for space heating, water heating or a combination of both.
Hot water for space heating is sent through a radiator or radiant heat system, or used with
an air handler to provide heat to your building. Natural gas boilers are also used to provide
hot water for your building.
If you are replacing an older boiler, or building a new facility, installing a condensing or high
efficiency non-condensing natural gas boiler will improve the energy efficiency of your facility
and lower your operating costs.
Standard boilers are on average 76%* efficient while HE non-condensing boilers are up
to 85% efficient and condensing boilers are up to 98% efficient.
||High efficiency non-condensing boiler:
|Up to 98% efficient
||Up to 85% efficient
|Re-uses heat from flu gases that would have been exhausted from the building
||Does not re-use flu gases but operates more efficiently than standard boilers
