This is for those of you who have radiant in floor heat. What are you using for a thermostat? Are you using an in the floor sensor? If so, what do you leave the floor set at compared to your desired room temp?

Currently I'm using a standard air temp thermostat, regular old analog round dial mechanical. Been tempted to try something else but not sure what to use either.
I did put an extra tube in the floor for a sensor.
Your floor temp will depend on what your desired room temp is, and also what your heat loss is. Obviously the more heat you lose, the more you have to put in, the more heat you lose the hotter your floor will have to be.
Typically my floor runs 2-5* above the room temp depending on what the outdoor temp is.

The brand of thermostat I'm using is Azel, it's what Radiantec sent me. I am not using a floor sensor. I keep mine set at 60*.
I have both an air and a floor thermostats that are not connected. My air t-stat kicks on the blower system which works with a water coil and a gas backup in case the floor and water heated air cant make it happen in about ten minutes time.

This is what I had also. It just so happened to get bumped a couple of times last winter, so I just picked up a non-programmable digital Honeywell for less than $20.00.
Works fine for my setup. I just set it & forget it.

does anyone use an outside ambient temperature controller? It monitors the outside air and works in concert with your thermostat.

That would be called an outdoor reset. I have one for my boiler, just haven't had a chance to install it yet.
I just have air temp thermostats for the house/garage. Only problem I have is that during the fall and spring it has a tendency to overheat the room. I think the outdoor reset would help with that... and I'm sure a floor sensor would as well.

Same here. I set it at 56*, and I can warm it up to 60* by working in it with the lights on. Here in CO, 56* is t-shirt weather.

Help me understand what an outdoor reset does. If it matters, I use the same boiler for my floor and to heat an area of the driveway for snowmelt.
Thanks,

Measures outside temp and adjusts the boiler's water temp based on that. More run time on circ pumps and less run time on boiler.
Pretty much if it's 50* outside you don't need the boiler to run at 180*, but when it's -40* you do.
Some of the newer boilers already do this, also they are "MOD/CON" while means they don't fire at 100% if it's not needed and also are condensing (most anything over 93-95% will be a condensing boiler)
