under floor heat

jimmy21 · 03-01-2009, 12:35 PM

I was just wondering what the cost of underfloor heat is. I've heard everyone loves it, but i don't have a huge budget. The bathroom is 8x10, but i wouldn't need to heat the entire thing

Hot water radiant or electric?
Going under tile?

A small matt can cost $300, programmable thermostat another $145. I bought the wire for about $369 & a programmable thermostat. I had enough wire to do the bathroom & the hallway outside the bathroom

If 8 x 10 is the entire room, you probably only need about 50sf of element as you don't heat under cabinets or permanent fixtures.

Come back with answers to the questions posed here and I'll come back with costs for line or low voltage systems out there you can buy and install yourself if you want.

About to remodel a similar sized bathroom and have asked one supply house this same question. They (counter helper) said approx. $12 to $15/sq. ft. That seems high, but I haven't done any more looking yet.

It about right for a low voltage cable system. A line voltage 'mat' should be about 15-20% less for a good one, both with digital progarmmable tstats.

There are lots of different brand mats out there. If you choose to go with line voltage, be very careful with it and monitor the system AS the tile is going in. Then test it immediately after to be sure the element hasn't been damaged. Damage to line voltage elements is next to impossible to find.

Most important with line voltage mats is don't over-buy. Buy what you need or a little less. NEVER cut or even nick the element and keep the spacing right.

electric. I don't care if it was line voltage or low voltage. Whatever would be cheaper. But it sounds like i would be into it in the $400 range after tstat and wire?

oh and yes, under tile

Given your perameters and that you need 50sf of coverage, that would be about right.
