 A radiant floor heating system is a great solution that will provide heat to different areas of a building in a very simplistic way. It can be a cost-effective way to heat an area using less energy than traditional methods and other heating alternatives. But what is the actual cost of electric heated floors?

Factors to Consider When Calculating Costs

To determine how much the radiant floor heating will cost, it is important to analyze the ​insulation level of the area that will have the system installed. Also consider, the number of openings, such as windows and doors and if there are other heating sources that can be used in the room. Sometimes, these types of systems are only used as complementary resources to keep the room warm. It is also important to consider whether the installation is new or is part of a retrofit project.​

Radiant Floor Heating Installation Costs 

Depending on the type of installation, the cost will vary between $7 to $19 per square foot. Many factors, including the ones indicated above, will be factors when determining your construction cost. Usually, new systems will be less expensive as all required material can be installed in the concrete slab rather than installing it during the retrofit process.

During new construction, the materials required will be close to $6 per square foot, but that does not take into consideration the heat source. An electrical radiant floor heating system will be more costly to operate than a hydronic radiant floor system. 

One key factor during the estimating process is the accessibility to the subfloor and will also depend on how much roof and floor will be removed during the installation process. A thin electric mat installed in thin-set cement will cost $500-to-$600 for an average size bathroom and it will operate on less than 10 cents a day of electricity. As average contractors will charge between $1,700 and $4,800 when installing radiant floor heating systems. Some other important factors to consider are:

  • Cost for material and delivery
  • Cost to protect the structure and the room on which the installation will be made.
  • Cost to assemble the radiant floor system
  • Cost associated with cleanup and debris removal
  • Insurances, overhead, mobilization and hourly rates.
