Im putting tile floor in house up North and was looking for some input on electric radiant heating . Approx. 200 square feet. I have never used it before, its for my own house and was hoping to get some feedback, good or bad. Thanks Bill

    Is this for supplemental warmth in the floor, or is it to heat a room? Makes a difference.

    You can figure a maximum for a comfortable floor of around 20 BTUh per square foot of floor -- or around 4000 BTUh for that area. Will that be enough? Have you figured the heat loss of the space, if this is to be the primary heat?

    Also, depending on where "up north" is, keep in mind that electric heat isn't cheap.

    Electric (in a small area) is cheaper up front and more expensive down the road. I think it makes the most sense for areas like bathrooms and kitchens where you put it on a timer so you get that "warm floor" feeling in the morning without running all day/night and spinning your electric meter.

    If you decide to install it, I would recommend verifying the Ohm readings after every step of construction. The wires are easily damaged.

    Electric is easier to install and more expensive to operate.--"up North." Hydronic (hot water tubing) is more difficult and expensive to install and cheaper to operate.

    Electric might be a bit $$ for that size area? I have used kits like this for small bath or kitchen areas.
    The Loud mouth is a handy meter that attaches while you are installing to notify of damage to the cable. A kit like this is probably around 10 bucks a square foot.

    If you can tube the area with pex, you have options for heating down the road.

    I wasn't clear enough, just to warm floor. I have electric baseboard that is sufficient. Up North to me is Lake Ariel , PA.

    Up north is Pennsylvania? Hmm. Well...

    But you should have no trouble with electric radiant for that application. You can get either cable or mats. Even Amazon has them -- preassembled floor mats.

    I put Suntouch brand one in my bathroom downstairs just because when I built the house, the bathroom was put on the same zone as the office. I already have radiant in the floor, but with my wife needing the bedroom to be cold, the bathroom winds up being the same way. It is a small bathroom, so i just have a 2' x 8' piece right down the center, and it works great. Since out electricity here runs around 26 cents, I do only have it on a limited time. I need to spend a little time and read the manual, because I am not sure if I can set it up with a timer sequence, but I believe I can. At this time, I am just turning it on as needed.

    My son did almost the same thing in a house he had in Burlington, VT, @rick in Alaska -- worked very well indeed. He did have it on a heavy duty timer -- Intermatic, as I recall.
