How Much Does It Cost To Install Hydronic Radiant Floor Heating?
Hydronic Radiant Floor Heating Costs
Hydronic floor heating is the most efficient space heating alternative. This is due largely to total-floor radiation that will heat floor mass and the air as heat rises from the entire floor area. Personal comfort is excellent, in some cases air temperature can be 3ºF less than equivalent comfort using forced-air heating.
Hydronic floor heating requires a boiler whose hot-fluid output will be circulated by pumps to radiators that are integrated within the floor. The boiler and other equipment will occupy space in a prepared mechanical room with electricity, water, and fuel installations.
You will find that the cost of hydronic radiant floor heating varies by type of unit, its heating and pumping capacity, efficiency ratings, the extent of necessary floor-installations, and the labor rate. In the following table the Labor Cost figure is what the able DIY person should expect to save by performing the corresponding tasks.
Hydronic radiant floor heating: provide and install the complete system in a wood-frame single-story house of 2,800 square feet and fully prepared with exposed sub-floor structure and space in the mechanical room with fuel, water, and electrical outlets. Include all related materials, supplies, transport, equipment, finish trim, final adjustments, and clean-up. New flooring not included.
|Item||Unit Cost||Quantity||Line Cost|
|Basic: mild winter climate; install 35,000 BTU/h boiler and 2,800 sq.ft. of radiant floor tube-and-plate circuit. Include floor and mechanical room integration and hookup of gas, water, electric, drains, valves, control wiring, thermostat, testing and balancing.||$6,797||each||1||$6,797|
|Upgrade Moderate: additional to Basic, moderate winter climate; install 70,000 BTU/h boiler.||$621||each||1||$621|
|Upgrade Deluxe: additional to Moderate, harsh winter climate; install 105,000 BTU/h boiler.||$633||each||1||$633|
|+ Labor Cost (Basic)||$40||per hour||120||$4,800|
|+ Labor Cost (Moderate)||$40||per hour||2||$80|
|+ Labor Cost (Deluxe)||$40||per hour||2||$80|
Typical capacity unit conversions are:
1 Ton = 12,000 BTU/h = 3.5 kW = 4.6 BHP
Domestic heating and cooling capacity demand always depends upon regional climate zone conditions. In Phoenix (AZ) for example, 1 Ton of cooling capacity will cool about 500 square feet of living space (well insulated and sealed). In Minot (ND) it will cool about 650 square feet (or 30% more).
Heating capacity demand per square foot follows a similar but reversed regional pattern. In regions near the 49th parallel for example, each Ton of cooling capacity indicates the need for 3 to 4 Tons of heating capacity.
Other considerations and costs
- Floor-installations cost will vary with floor conditions.
- Energy efficient heating and cooling will save money, and in some cases rebates may be available.
- During the initial inspection the contractor should inform the homeowner of any and all necessary modification or upgrade on electrical circuits or building structure.
- Labor cost will rise with a “hidden” installation in a finished environment.
- These prices are for service in the immediate area of the provider.
- Taxes and permit fees are not included.
