How much does it cost to run a heated floor?
A typical heated floor draws about 1200 watts. Used 6 hours a day, that works out to roughly $1.22 per day, $12.24 per month, and $146.88 per year on an average electricity rate of 17¢ per kWh. Radiant floor heating is comfortable but runs for long stretches.

Based on 864 kWh per year. Adjust the price per kWh to match your latest electricity bill for an exact figure.
The number that matters most is your own electricity rate. Rates range from under 11¢ per kWh in some regions to over 30¢ in others, so the same heated floor can cost two or three times as much depending on where you live. Enter your exact rate in the calculator above to get a figure tailored to your bill.
Over a full year this heated floor uses about 864 kWh of electricity and is responsible for roughly 345.6 kg of CO₂ emissions on an average grid. Reducing run time, or switching to a more efficient model, lowers both the cost and the footprint.
If this heated floor is one you use daily, even small efficiency gains compound. Cutting its usage or wattage by 20% would save around $29.38 every year — money that an efficient replacement can recover over its lifetime.
