that will still keep you warm.......hopefully you had someone or are going to have someone do a heat loss and design layout for the tubing so that you don't have to run way high temps. to get the heat outout you need to be comfortable.

    radiant temp.

    What is the ideal temp. for radiant heat in concrete and wood floors in a home?

    Around 85° when very cold outside. A temp around 82° will feel "neutral" to the bare foot even though a bit cooler than the actual surface temperature of the skin on the sole of the foot. 90° is considered the absolute maximum.

    The anwser to that question is

    what the heat loss and radiant design calls for that particular structure and how the radiant is being controlled. To come out and give a temp based on another job is wreckless.

    You have to understand

    That there is no single "ideal temp". The floor should change its temperature in response to changing outdoor conditions. The heat required in your home is a lot different at 40* than it is at 0*. The floor should match what is going on with the heatloss of your home. You can't run the same temp all the time and expect the best comfort or efficiency.

    I think

    what Mike is talking about is max. floor surface temperature. Depending on the R value of the floor covering product, and thickness you could calculate the temperature below the floor covering material.

    Some manufactures have set limits for temperatures their products are warrantied for. Any laminate with glue will have temperature limits. Same for carpet and pad, vinyls, plywood, wafer, sheetrock, etc.

    There are ocassions when radiant floors will not, alone, be able to meet the heating load of the space.

    Virtually all the design software out there will pop up a warning when you reach this temperature. I agree 85 is the max. surface temperature for residential. 90F surface gets very uncomfortable if you are on that floor constantly. It may work in some commercial spaces, storage, etc. Or snowmelt :)

    Always start with a design and load calc to discover the temperatures involved.
