This blog post is an FAQ guide on electric radiant floor heating by WarmlyYours, covering how underfloor heating works, comparisons between electric and hydronic systems, and radiant heating versus forced-air central heating. For a comprehensive overview before diving into the FAQs, see our complete guide to electric floor heating pros, cons and real costs. Key points include: electric systems cost $10-$20 per square foot, heat up in 30-60 minutes, and are ideal for remodeling projects; radiant floor heating is 25-40% more energy-efficient than forced-air systems with zero duct loss; and radiant systems operate at lower temperatures (85-104°F) compared to forced-air's 120-140°F while providing even heat distribution and better indoor air quality.

If I have hot water in floor heating and a wool rug with rubber underlay..would that cause any problems

Guest User July 31, 2023
WarmlyYours Responds...

That could cause a problem with "trapped heat" due to the insulative properties of both wool and rubber. It will depend on a number of factors (size and thickness of the rug, the r-level of the rug, the size of your heating system) but there is a good chance that this could negatively impact the performance of your heating system, unfortunately.

What is the optimal balance thermostat setting between comfort and energy efficiency?

Guest User April 12, 2025
WarmlyYours Responds...

Thanks for taking the time to read and submit a question. The answer is that there isn't a perfect number because there will always be a number of variables (like the insulation level in your home, the weather and ambient temperature in your home, and the heating system you've selected) that will greatly impact this number. However, do generally recommend people start with the floor temperature (not the temperature in the room) to 82 degrees Fahrenheit. This should be a good starting point for comfort. You can get an idea of how much it will cost to run the system using our Operating Cost Calculator here: https://www.warmlyyours.com/floor-heating/cost-calculator Hope that helps!
