Floor Gas Furnace Heating Costs

Indoor Cost Guides      Air-Conditioning & Heating (HVAC)      Floor Gas Furnace Heating Costs

The domestic floor-furnace provides for heating a single zone without ducting other than a vent to the exterior.

Sizing the furnace per area of heated zones depends primarily on the regional climate assuming that house insulation properties are adequate. In the colder regions about 70 BTU per hour (BTU/h) are required per square foot of heating zone, in the warmer regions about 35 BTU/h are required per square foot.

The cost to install average gas floor-furnace heating depends upon type, heating capacity, preparation and special needs, and the labor rate.

In the following table the Labor Cost figure is what the able and prepared DIY persons should expect to save by performing the corresponding tasks.
