How Much Does Radiant Floor Heating Cost to Run?
Think radiant floor heating is too expensive to operate? Think again!
Many homeowners and even some professionals assume that electric radiant floor heating will send energy bills soaring. But the truth is, radiant floor heating is often surprisingly affordable to run-sometimes costing less than your daily cup of coffee.
With the WarmlyYours Operating Cost Calculator, you can get a personalized estimate in seconds, based on your room size, local electricity rates, and how many hours per day you plan to use the system. Whether you’re a homeowner dreaming of cozy, warm floors or a kitchen and bath professional helping clients make informed decisions, this tool takes the guesswork out of radiant heating costs.

Only Heat Where You Walk: How to Enter the Right Square Footage
When using the calculator, you’ll be asked to enter the square footage you plan to heat. It’s important to remember that you’re not heating the entire room—just the areas where you walk and stand.
In most projects, that means:
Leaving a 12-inch (1 foot) perimeter around the walls unheated
Avoiding areas beneath permanent fixtures like bathtubs, showers, vanities, and cabinets
Only heating under furniture if it’s floating or has adequate clearance (like wall-mounted vanities or pedestal sinks)
This approach maximizes efficiency while reducing unnecessary energy use and material costs.
Pro Tip: Sketch your room layout and highlight only the areas with open floor space-those are the zones you’ll want to heat.
Set Your Daily Usage
Use the interactive slider to select how many hours per day your system will run—anywhere from 1 to 24 hours.
To get the most accurate estimate, consider how the room is used throughout the day.
- Do you use it more in the morning or evening?
- Is it occupied longer on weekends?
- Does your usage differ on workdays vs. days off?
Think through your daytime and nighttime routines, then come up with an average number of hours based on typical weekly use. This will help you get the most realistic cost estimate for your lifestyle.
What Makes This Version Streamlined?
This embedded calculator is designed for speed and simplicity. It gives you a reliable estimate using just a few inputs, without needing to specify system types or room categories.
You’ll be able to:
Get a cost estimate based on your location and usage
Understand your expected energy costs with no guesswork
It’s ideal for fast planning, early-stage budgeting, or on-the-fly project comparisons.
Example: Heated Bathroom in Chicago
Let’s say you’re heating a 50 sq. ft. bathroom in Chicago, using the system for 4 hours a day and paying an electricity rate of 13¢ per kWh (a typical residential rate for that area).
Once you enter those details into the calculator, you might see:
$0.32 per day
$9.60 per month
$115.20 per year
These numbers reflect energy use only when the system is turned on—which, in climates like Chicago’s, typically means daily use from October through April. During the warmer months, most floor heating systems are turned off or used sparingly.
So, while the calculator shows costs on a daily and annualized basis, your actual usage may vary by season, making radiant heat even more affordable in practice.
