To setback or not to setback...

That is the question....Should I setback my thermostat when using an outdoor reset control on my oil fired boiler?

My system consists of an oil fired boiler piped in paralell to the 2 feed and 2 return lines of an unused coal fired boiler that was originally a gravity feed system. There is lots of 2 1/2" feed and return piping and 13 cast iron radiators. That's a lot of water to reheat when returning from setback.

Does the benefit of thermostat setback outweigh the cost of the return from the setback?

    i wouldn't

    I mean, you can try it both ways, do your own little experiment.

    If you need it nice and toasty when you wake up, you would have to start recovery pretty early in the morning.  If it's ok a few degrees cooler in the morning, you wake up and are out the door all day, then you could leave it lower, and go for your recovery mid to late afternoon, with the help of any solar gain on the home. It depends on your lifestyle & comfort.

    I wouldnt recommend it on a system with that kind of volume. You will be dissapointed at the recovery off the setback. I think that even the H/W adaptive intelligent recovery tstats would not be able to anticipate that.
