The house thermostat is in the dining room,...at one corner of the house,......directly over the boiler room. Yup, you guessed it,....the warmest room in the house :mad: Far end of house is 66 degrees. Dining room 72 degrees. Thermostat set for 70 degrees. Heat vents in dining room closed return vents in dining room open. Not sure who installed the thermostat at this particular spot but moving it has been added to the to do list. Yes,...I could turn the furnace blower fan on to even out the heat but I'd rather that not suck juice anymore than it has to.

I have the same problem. The bedroom with our bedroom zone loops T-Stat in it is directly over the boiler room. It's generally about 3 - 4 degrees warmer than the other 3 bedrooms. I've been telling myself to move that T-Stat for a few years now, but with a finished ceiling in the basement it would be a chore. I've considered running it up through the attic and then down into one of the other bedrooms from above, but the attic has lots of itchy pink fiberglass stuff in it to discourage me from pursuing this project.

I have the same problems! I guess I'll just set the TT to where the house is comfortable and not really obsess over the TT setting temp. Once it's cold and the furnace blower fan runs more frequently, the difference in room temps SHOULD decrease,...I hope. :roll:

I have some temperature variances too, but like you said once the blowers are running more, it should even temps out a little. I don't mind the bed room a few degrees cooler.

I used a Honeywell wireless thermostat to put out 2nd story on its own zone.

DId you try to close the supply vents and returns in that room, the return air is pulling through that room from your other rooms, as long as the system is not a "single central" return design you should be able to close all the vents to that room and rely on the radiant heat coming from below to keep that room comfortable while keeping the rest of the house at a more comfortable uniform level...

Also are the vents actually closed, I have noticed some registers do NOT close tight, removing them and adding a foam vent block will ensure no impingement... After you stop the airflow from that room you should be able to decide if the units radiant output is enough to replace the heatloss, if its not, then open an airway in a supply vent and a return vent {75% as much as the supply you open, so if you give 200cfm of supply only 150 of return is needed as a starting point} until the room is "more" uniform... I wouldn't move the thermostat since that is just a band aid, get the system correctly balanced and you will be much more comfortable and efficient, this is what I do for a living, 15 years as a master mechanical contractor {with master sheet metal}...

good luck...

@ imcloud1: thanks for the advice. Yup, need to rebalance the system since the equation has changed. Another reason I want to move the TT is that it is directly backing a double wall oven on the opposite side of the wall in the kitchen. When the ovens are on, the TT is nowhere near reading the room temperature. I'll get the system balanced eventually.

well that does sound like very poor t-stat placement, Honeywell Prestige units are very nice and can be setup wireless and you can change them with your smart phone from anywhere in the world... Although I have moved and installed retro thermostats in places you would think were impossible, that is where the micro cams, fish stix, and flexible dril bits come in very handy http://www.aliexpress.com/item/13mm-x-4 ... 24186.html ....
