Thermosta Recommendation

Kungur Member Posts: 49
As I move along with my radiant heat retro project I was wondering about thermostats. Is there a specific kind to use for radiant heating? Any recomendations would be appreciated.

    I used to use the White-Rogers 1F80-0361, but it's been replaced by the -0261.  If it's anything like the previous model, it is very reliable, easy to set up and homeowner friendly.
    8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

    our go-to

    is the Tekmar 509 (a 508 with a floor sensor). if you're going to do radiant I think floor sensors should be standard equipment.

    I second the tekmar 509 (same as a 508 but packaged w/floor sensor) easy to use, very flexible, built solid and look really clean.

    Comfort dials

    Oventrope non-electric controls work wonders, are extremely simple and provide the ultimate in comfort

    I'm with you Jeffery....

    Non electric TRV's in 2/3's of my houses, and when I get around to hydronicing the third, you can bet it will be non electric TRV's.

    It's not so much a case of "You got what you paid for", as it is a matter of "You DIDN'T get what you DIDN'T pay for, and you're NOT going to get what you thought you were in the way of comfort". Borrowed from Heatboy.
