    I was curious if anyone here has an experience with building or living in a home built on a slab?

    We're in a newly constructed house and it's on a slab without any infloor heating. This is our first fall/winter here and we find the floor always cold despite the heat being on 73-75 constantly. Is that normal?

    Concrete holds hot/cold so without any in floor heat, you're gonna have icy cold floors. Time for some slippers :D

    I'm surprised the local building code would allow slab installations without in-floor heating?

    Absolutely foolish for a house on slab not to have infloor heat

    Actually, I had in-floor heating in my previous home and we weren't on a slab. When we rented this place it was in the spring so it didn't matter a whole lot. All the houses in this area are on slabs with out in-floor heating and when I questioned the contractor, he just said "it passes the city code so who cares"., which really surprises me!

    What type of heating do you have?

    Forced air mostly. In areas where I've had to do a re-pour to fix the slab I've added some in-floor. I also have sub-flooring on top of the floor everywhere else which helps; I've smashed both my feet (separate incidents) so I suffer from pain in them regardless... I take slippers with me when I travel south even...

    Any idea how drainage is around the house? If the ground under the house is wet at all the moisture will suck the energy out of the slab like crazy. Ideally there should be insulation all around the outside and really good drainage to keep it dry.

    This. Insulation under the entire slab isn't as important as around the perimeter.

    Love the comment from the contractor about it passing code... :lol: So typical.

    The ground becomes the insulation when there is no moisture in it.

    Drainage is fine, it's just once the concrete floor is cold it stays cold and you're constantly trying to heat the room but the floor is always cold. We have a heat pump and those convectAIR heaters. Neither works well to heat the floor, but I'm thinking the convectAir works better but probably cost more.
