Electric Radiant In-floor Heat

| Posted in Energy, Heating & Insulation on April 5, 2003 01:26am

Hi everyone. I live in Halifax, Nova Scotia, in a 23-year old 2 story, approx 2300 sq feet. We just bought the house last summer, and have been doing a lot of updating since then.

I’m in the planning stages of a bathroom reno, which will include adding an ensuite bath, adjacent to the existing bath, connected by a passage door – about 180 sq feet total. I’m planning on replacing the existing vinyl flooring with ceramic (on plywood), and would very much like to heat the tile electrically, for those cold winter mornings (and nites).

Our house has electric baseboards, but our primary heat comes from 2 woodstoves, so any under-tile heat would be for comfort purposes. I’ve done a little checking – Home Depot, local tile retailer, websites – and the cost of these systems may be a bit more than our tight budget will allow.

My question is, has anyone put one of these systems together themselves, rather than buying an off-the-shelf one? It seems like it shouldn’t be that complicated – just some wire, maybe a transformer and a timer switch. I’m not sure why I would need a $200 thermostat (that’s what the tile retailer quoted me for the thermostat for their “Warm Tiles” system), when all I want would be to have the heat come on, for a few hours in the morning, and then again in the evening. A simple programable timer should be able to accomplish that.

Any comments would be appreciated.

    YOu could probably use timers and forgo the fancy thermo.  There are options as well, thermaflex has a cheaper programable timer that uses the ambient temp insteat of the tile temp.  It's not as responsive as the thermo that uses a sensor against the tiles but it works, for that matter any thermo/timer should work.  Whatever you do, make sure you have a GFCI or your desire to save a few $ could kill someone.  Personally I go with the full set up from THermaflex as it comes with garentees etc... and if you end up having to tear up your floor (or rebuild your house after it burns down) you will end up regretting the small intial savings.

      Thanks for the comments. You're right that it's definitely not worth saving a few bucks, if it means safety is compromised.

    I can't offer help on the heat, but you may want rethink the ceramic on ply, and go with cement board.
