Thermostat help needed

could install some inline duct fans to the ducts for the cold rooms they can be controlled by a high voltage thermostat or tied to a conventional switch. The will keep running even after the furnace/heater stops and will circulate warmer air from the other rooms into the cold spots.....

I do something similar from my stove room into my garage. Saves my 240V electric heater out there from working so hard....

 

Is it possible to "balance" your hydronic system so it would send greater volume to the bedrooms than to the LR?

 

Sorry about that, In my haste, I had read oil boiler system. I guess I need to go for another eye appointment?

But that only makes it easier. Typically, the 6" branch runs have what is called a balancing damper in them. Close down the dampers to the t-stat area (loosen wing nut on damper handle, re-position damper, tighten wing nut). This will re-direct air to the far ends of the house. The balancing dampers can be found next to the trunk line normally. Don't close down the damper all the way though.
When the furnace runs, it should direct more air to the bedrooms this way.

 

Bocefus' option 3 sounds like a winner. Be careful running 2 thermostats on the same circuit. I actually killed on last year trying to do the same thing. You can add resistors in so the circuit can only run one direction, or use a switch which is what I ended up doing so only one thermostat works at a time.

Also be careful closing off vents in the house. I've had 2 HVAC guys, one a good friend, tell me that shutting off too many vents will end up putting too much stress on your blower and end up burning it up. It's probably better to install an in-line fan for those longer runs.

 

Why not set the the to on so it runs all the time? This should cycle the air throughout the home at all times.

 

My thermostat is in the dining room...well centered in the house, but that's also where the pellet stove is so it's always warmest in that part of the house. I installed these this year and keep the remote sensor back in the master suite....furthest from all heat sources thus always the coldest.

The thermostat is set to read from the remote sensor so that coldest part of the house is always at the set temp. When I run the pellet stove (hasn't been much this year yet), I shut the vents down in the rooms it handles well so the furnace doesn't do much to maintain the far end of the house.

I've also changed from "heat auto" to "heat on"...and the entire house is a much more constant temp.

I shopped around and found a little better prices than these.....it was just easiest to find and post these.
