Electric Floor Heating - Operating costs for heated floors

STEP Warmfloor® radiant floor heating is a very cost efficient heating solution compared to traditional heating solutions and other radiant heating alternatives.

Calculations indicate that STEP Warmfloor® uses 40 to 60% less energy to gain the same heat output compared to cables and water tubing (hydronics). But what is the actual cost of electric heated floors? This depends on a variety of factors including how well insulated is the area to be heated, are doors keept closed, the outdoor temperature, prefered indoor temperature, room size, price of electricity and is radiant heat the primary heat source or used just for floor warming.  If you already have a primary heat source, you can use the infloor radiant heating solutions as complementary heat or only for floor warming using an air sensor or a floor sensor.

Our electric floor heating system is not only a radiant heating solution that can take away the chill from your floors for a couple of hours in the morning and evening. It is a cost efficient radiant heating solution to heat a room or a complete house.

To give you an indication of the cost to heat a room or a larger area view the tables below or use the operating cost calculator.

As the table illustrates, the operating cost of running STEP Warmfloor® 24 hours a day for 6 months is as low as $19 for a 40 sqft bathroom with standard insulation.

A cable system would require 2.5 times more wattage to gain an equal heat output thereby increasing the operating costs from $19 to $47.

Running a radiant floor heating system as a on and off system requires the system to run at full power until the temperature reaches the set level (ambient or floor temperature).

STEP Warmfloor® recommends keeping the system on and maintain the desired temperature at all times. This will help reduce the total heating costs and avoid an inefficient on/off system.
