Thermostat on warm wall.

There is a builder's grade Honeywell stat at one of my local suppliers with a raised, vented backing plate. I was hoping for another option, though.

    Thermostat on warm wall.

    I have a client with a thermostat set on a wall with heating pipes behind it. The wall is warm to the touch and the stat satisfies too quickly, as you might imagine. I want to replace the T87 with a model with a little air space behind it.
    Any thoughts?
    Please resist the overwhelming urge to say "move the thermostat".

    Never seen a thermostat with a little air space behind it.

    Suggest you mount some rigid insulation between the t'stat and the wall, but the MOST important thing is you seal perfectly the hole where the wires come out. The warm air will get you just as well as the conduction.

    Note I did not tell you to do the right which is, of course, move the thermostat....

    You could get a wall stat with a wireless remote sensor and mount the sensor in the right spot which is anywhere but on a hot wall....

    Stand-off bracket

    I agree with Jim's points re: sealing the hole and insulation. Thinking out loud you could also make a sheetmetal hat-channel type bracket to hold the thermostat a half inch or so off the wall. Air being the insulator it is, it should provide enough air space. But do seal the hole or as suggested, move that sucker.

    suggestion

    Mount the thermostat on 1/2 inch wood blocks. And fill the hole with expanding foam.
