Radiant Heat Cost by Type

For residential settings, there are two main types:

  1. Electric system installations cost from $1,760 for a 160 square foot master bathroom to around $16,500 for a 1,500 square foot house. Average price is $11 per square foot. Because it can be installed as mats, the installation cost is significantly less than a hydronic system.

  2. Hydronic installations cost from $6 to $20 per square foot with an average of $13 per square foot. Operating costs are lower than electric systems because water conducts and holds heat very well, meaning there is less actual operating time.

The water heater will increase the price of installation, but will still be one of the more affordable radiant heat options. Installing a water heater costs $770 to $1,450. Boilers are far more expensive than water heaters and installing a boiler costs $3,500 to $7,700.

Hydronic Radiant Floor Heating Cost

the cost to install radiant floor heating is $6 to $20 per square foot

Installing a radiant heat boiler costs from $6,000 to $9,000 and an extra $6 to $20 per square foot for the hydronic heating system in the house. Hot water radiant heating costs less to operate than electric systems because water conducts and holds heat very well, meaning there is less actual operating time.

Heated Floor Installation Cost Factors

It requires 8 to 16 hours to fit 1,000 square feet of heating material and $75 per hour for a plumber to install it. Total labor costs for a project are $600 to $1,200.

As with any contracted job, factors that will affect your overall bill include:

  • Distance to the job site.

  • The workload of the contractor.

  • Local labor rates.

  • Clean-up and disposal of debris.

  • Size of the area requiring heating.

Retrofitting by Flooring Square Footage

The square footage of your home will help to determine the price. Oddly enough, smaller projects tend to cost more per square foot than larger ones. For example, a 400 square foot area might cost 80 percent more than a 5,000 square foot area installed. This is because a larger area is usually a lot more open and easier to work in.

Temperature Zones

If you are installing a radiant floor heater as a whole-house system, you may find some rooms require different amounts of heat to be comfortable. This may lead you to establish temperature zones where a living room might be kept at a warmer temperature than a bedroom. Larger rooms may require more heat than smaller rooms.

Radiant Cooling

While most radiant systems are thought of for heat, you can also use radiant systems for cooling. Putting them on the floor will not be very cost-effective because cool air falls. The best place to install a radiant cooling system is in your ceiling. They will need some added equipment, such as a chiller and possibly a dehumidifier.

Pre-Fitted Subflooring

Traditional tubing systems are secured with silicone sealant requiring up to 24 hours curing time. Using modern subflooring panels with pre-fitted channels allows you to install tubing straight away, making it faster to install and lowering the labor cost.

Floor Heating Cost to Operate

The average price of heating a 100 square foot space is between $1 and $5 for 24 hours.

Energy Savings

The average price to run a radiant heating system for 24 hours non-stop is $3 compared to $20 for traditional air heating systems. Water can hold 3,500 times the heat than air can. This allows you to operate your radiant floor heated home 6 to 8 degrees lower than a standard air-heated room.
