Is electric floor heating worth it for a sunroom?

If your main issue is cold floors and uneven comfort, it’s often worth it. Radiant heat warms from the ground up and can help you use the sunroom more months of the year.

What’s the best flooring for radiant heat in a sunroom?

Tile and stone are top choices because they conduct and hold heat well. Other floors can work too—what matters is selecting the right system and controlling it properly.

Why are sunrooms harder to heat than other rooms?

Sunrooms often lose heat faster because of large windows , more exterior exposure, and sometimes lighter insulation. Radiant heat helps by improving comfort at the floor level where you feel cold first.
