Cost factors to install heated floors

The cost to install heated floors depends on the existing building conditions, the plumbing design, and whether the system needs a new boiler.

  • System type – Hydronic systems are best for an entire home or large areas, while electric systems are better for smaller spaces or individual rooms.
  • Project size – Smaller jobs typically have a higher installation cost per square foot.
  • Labor rates – A plumber costs $45 to $150 per hour for installing a hydronic radiant system.
  • Floor design – Complex custom layouts with many corners take longer to plan and install.
  • New construction vs. retrofit – A retrofit costs 50% to 80% more than new construction and requires floor removal and home adjustments from the increased floor height. Floor removal costs $1.50 to $3.00 per square foot on average.
  • Electrical requirements – An electrician costs $40 to $100 per hour for installing electrical heating and making system upgrades.
  • Foundation type – Many concrete-slab foundations send heat down into the ground soil outside, so installers must put insulation between the concrete subfloor and heating elements.
  • Thermostats and zoning – A new thermostat installation costs $140 to $350 to control the floor temperature. Each room or separate heating zone needs a radiant-heat thermostat. An HVAC zoning system costs $1,700 to $4,500 to centrally manage all zones.
  • Replacing old flooring – Removing and disposing of old tile or wood flooring costs $1.50 to $10.00 per square foot.
  • Existing boiler modifications – Hydronic radiant systems need extra valves and piping connected to the existing boiler to regulate floor-heating temperatures.
  • New flooring material – Installing new flooring costs $6 to $10 per square foot on average, depending on the material and customization.
  • MaintenanceBoiler service costs $70 to $350 for an inspection or cleaning.
  • Building department fees – Permits and inspections cost $75 to $180 on average, depending on the system size and local regulations.
  • Subfloor repairWood floor repair costs $35 to $80 per square foot to replace small sections of the subfloor.
  • Tax credits – Installing a new geothermal heat pump or solar panels to power radiant floors gets a 22% to 26% renewable energy federal tax credit. Local rebates may also apply for ENERGY STAR appliances.

Whole-house underfloor heating cost

Whole-house underfloor heating costs $10,000 to $34,000 on average with an existing boiler, depending on the floor size and radiant-system type. Installing a new boiler to power the heating system costs $3,200 to $9,000 more.

Frequently asked questions

What is radiant floor heating, and how does it work?

radiant floor heating is a system of tubes or coils below the top layer of flooring that sends heat up through the tiles. The warmed air gradually rises and circulates around the room. Floor-surface temperatures reach 70° F to 85° F.

The most common types include:

  • Hydronic floor heating pumps hot water from a boiler through subfloor tubing. Subfloor water temperatures inside the pipes run at 85° F to 130° F.
  • Electric floor heating generates heat through electricity by running resistance cables under the floor.

What is the cost of in-floor heating vs. forced air vs. baseboards?

Alternative options to in-floor heating include:

Are heated floors worth it?

Heated floors are worth it for the benefits of:

  • More comfortable and stable indoor temperatures
  • Increased home resale value
  • Longer-lasting heating system

How long does in-floor heating last?

In-floor radiant heating coils or tubes last 30 to 50 years on average, depending on the system type, installation quality. A boiler used for hot-water systems lasts 10 to 20 years before it needs replacing.

Which floors work best for radiant heating?

Radiant-heating floor options include:

  • Concrete or tiles of stone, ceramic, or porcelain work best for radiant heating.
  • Laminate, vinyl, and thin-wood flooring work but have temperature limits.
  • Carpeting or thick-wood flooring can work but block more heat.
  • Glued-down carpeting and rubber flooring are the worst for radiant heating.

How much does a heated driveway cost?

Installing a 2-car heated driveway costs $6,900 to $16,000 on average or $12 to $28 per square foot for materials and labor. These prices include installing electric or hydronic systems underneath a new asphalt or concrete driveway.

DIY radiant-heat installation cost

DIY heated-floor installation costs $5 to $8 per square foot for radiant floor heating mats, depending on the brand, size, and voltage. Homeowners with construction experience can install heating mats before laying new tiles, stone, vinyl, or laminate flooring.

radiant floor heating mats:

  • Connect easily for larger floors
  • Are available in 120- and 240-volt models
  • Have a single power connection for easy installation
  • Heat the floor above but don’t have enough power to heat the whole room
