Two T-stats

[imported_krmereness]

Is it possible to run a forced air furnace with 2 t-stats? I have part of the house that can be heated with my pellet stove (this is where the only t-stat is currently) and another part that is cooler because the heat from the peller stove doesn't get pushed in as much. I would like to put a t-stat in the cooler part of my house.

You may extend the original thermostat to the area of cooler temp. You will not be successful controlling one furnace from two thermostats.

YOu may consider installing baseboard heat in the cooler rooms seperately controlled per room.

You may consider turning on the fan of your furnace to constant on to circulate the temp more evenly in the entire home.

Is it possible to have two thermostats installed, but only one of them is controlling the furnace at any given time. My idea would be to switch between thermostats with an "A"/"B" switch (as is used for audio speakers). Is this a viable option, or just a homeowner's ****amamie idea?

If you install them in parallel when either one of them is cold it will turn on the furnace. Both of them will need to be hot enough to turn off the furnace.

When an idea of two thermostats be connected it implies a room colder than other rooms indicating an imbalanced heating system.

Either the ducting system needs to be looked at in re-design or a secondary heating assist should be installed in that cold room with its own thermostat such as a baseboard heater on an outside wall.

In my case, I am interested to learn if I can control the furnace with only one thermostat, but have more than two thermostats available - one downstairs in the family room and one upstairs in a bedroom. The downstairs one would be used when the fireplace is not in use and the upstairs one while the fireplace is in use. The fireplace provides so much heat that the furnace would never go on. With this happening the bedroom upstairs would stay cold in the winter

Try turning on your furnace fan to constant on. This will help circulate the hot air downstairs to upstairs mixing the cooler air with the warmer are parts of the house.

If you put your thermostat upstairs it will just make your downstairs hotter.

I suggest those rooms not being heated by the wood stove should have zone heat such as baseboard heat to equalize that heat in that room maintained by a zone thermostat only controlling that room and still leaving the furnace fan on constant to equalize and reduce the use of those baseboard heaters.

Best advice I have. Been heating with wood 10 rick a year for 20 years in 3500 square foot home two story. It works as discribed above in my home and reduces heating cost. This way if your stove cools down the thermostat on your furnace will kick in and reduce automatically the use of the zone baseboard heaters.

Hope this helps
