Title: Thermostat reaching set temp to quick.
Post by: Axeman on October 04, 2012, 03:09:01 PM
Hi I have noticed that when my thermostat for my furnace reads 70 degrees and I turn it up to say 72 degrees it only takes a minute or two after the blower kicks on to get up to the set temp. Is that normal for it to get to temp that quick? I also need to mention that this thermostat only runs the blower on my furnace as i have an outdoor wood boiler and it is a digital/non-programmable type. I thought about trying one of the old style dial thermostats that have the heat anticipator adjustment on them to see if that would fix the problem or does that have nothing to do with what i am describing?  Thanks for any help!!

I'm not sure I understand the problem unless you are saying the thermostat is wrong and the home is not heating up. If you want your furnace blower to run longer it seems to me you could just drop your water temperature and that would do the trick.

Is the thermostat located close to one of your heat registers?  Just a thought...

I have the same problem. Except my propane tstat is a degree lower at all times compared to my stat for the blower only. I think its the fact that the heat coming off the radiator for your stove is a hotter heat versus propane. Good luck and I always keep my stove stat a degree higher

If you want them to read the same, most thermostats have an offset adjustment to make them match. Just look in the thermostat manual for instructions.

Axeman, I use my oil hot air furnace blower to push the hot air from the OWB heat exchanger through the duct work. My thermostat is set at 72 degrees. When the house cools and calls for heat the blower kicks on. The blower on the coldest nights only runs maybe at most five minutes. I've been using the high speed (central air speed) on the blower. That along with the air in the ductwork stays preheated from the OWB causes such a quick recovery. I've been told that you can switch a wire or two on the blower motor to change the speed. Haven't done it now going on six years. :)
