Fundamentals of Electric Radiant Floor Heating – Part 2

As discussed in Part 1, perhaps the most popular type of radiant heating is the electrical system, where a mesh of wires or loops of single wires are installed, spanning the area underneath the floor. Part 2 will discuss Advantages & Disadvantages and Expenses.


• Can retain heat for extended periods of time after being turned off.

• Subtle method of floor heating because at the right temperature, it’s hard to tell that radiant heating is functioning.

• Can decrease overall heating costs because your HVAC system will not have to work as much and it’s more efficient than space heaters.

• Perfect for use beneath naturally cool, hard surfaces like stone or tile.

• Easier installation for remodeling projects.


• Retroactive installations can be difficult. Much easier during construction or remodeling.

• Effective for warming floor surfaces as opposed to whole rooms.

• If used for the entire home, electrical radiant systems are more costly than warm water radiant heating.

• When wires or other components are defective, repair can be very difficult.

• Reduced effectiveness beneath hardwood, carpeting, or vinyl because heat can be trapped.


Homeowners should anticipate expenses at a minimum of $8 per square foot for electric radiant floor materials. To be conservative, an average estimate of $11 per square foot for materials only is adequate. A professional installation, including materials, will average $16 per square foot.

Although utility bills will certainly depend on the location of the home, operating costs of about 50¢ to $1 for a full day for an 80 square foot bathroom should be expected for an electric radiant heating system. If operations are limited to only 8 hours per day, expenses costs will range from 25¢ to 35¢ daily for an 80 square foot bathroom.
