Radiant heat thermostat setback - need advise, please?

I suggest NOT using set-back on your radiant system. The time it takes to cause a temperature change is too long to effectively use a set-back. Best to determine your comfort level by gradually reducing the temperature a day at a time.

I keep mine at 68 degrees and it is as comfortable as 71 degrees. I spend a lot of time sitting on the floor on those cold winter nights. You'll love it.

Could someone please give me some direction and information concerning how to use thermostat setbacks for in floor radiant heat? Specifically, what temperatures to use and how long to allow for warm up and cool down. This is our first winter in our new house and I'm not sure how to set the thermostats.

Here's my situation:
New, tight, well insulated, one-story ranch, approx, 2800 sq. ft. first floor and 3000 basement / Munchkin 199M 190,000 btu 94% afue modulating natural gas boiler / Rahau probalance distribution manifolds for 6 zones / Rahau oxygen barrier pex tubing in gypcrete / Flooring material is either wood or tile - no carpet.

I read somewhere on the internet that you can set radiant heat at 59 degrees and still be comfortable - is that true?

Thanks for taking the time to read this and any info you can provide will be greatly appreciated.
