I still think you could save fuel.

Much depends on type of construction. Some types are more thermally stable and do not respond to the rapid hourly or daily changes in the outside conditions.

My first home was a 1917 one story home built with 10" clay tile walls that were the studded out with full 2x4s and lath and plaster. - 9' ceilings and a flat roof. It also had an over-sized hot water boiler. radiators. In the winter the furnace would kick on every day or so and run and then go back to sleep. - Very safe feeling and economical, but it was dangerous because when you went outside in the winter because you had no idea of what was outside unless you had the TV on. - Dirt to heat at that time compared to the 10 year newer homes around it.

My next home was a 3 BR split 4 level (including basement) that was a little larger. Typical suburbia with 2x4s and fiberglass. With open stairs everything was really open. The furnace cycled very often as the structure cooled off. On the top level where the bedrooms were, no alarm clocks were needed because of the single zone and a programmable thermostat.

I had a lake home (1800 sf) that was built with 8" lightweight block, 2" XPS and brick for the walls. After a few years, I hated to walk in on a Friday evening in the winter and kick on the furnace (programmable thermostat set to 68F from Friday afternoon to Sunday night). I set the thermostat at a constant 65F (24/7)and found it cost me less than $50 a year to be able to walk in any time I chose to be there. No matter what the R-value said, the annual cost was low enough to do it and not worry because I had a means to be notified if there was a low heat alarm. Again, the thermal mass makes a big difference in the real comfort.

The mass has it's dangers. I arrived at my lake home early on a Saturday morning before a front came through. It was about 32F with big flakes coming down and when I pulled the car out of the garage 2 days later, I did not know the actual temp was -42F. I did know we had 20" of snow as I saw the picnic table missing because of the drifts. The drive into town for groceries reminded me of the safety situation. - I was not foolish because everything (electric, cable and phone) there was underground because the lower cost for the suppliers. Now, I live in a 2 story townhouse (4 units per building that is 1-1/2 to 2 stories with the units separated by concrete block party walls - 1980's construction) each unit has a corner, so only 2 exterior walls. This year we have had a month long string of -0F days and my monthly gas and heating and hot water finally got up to $80. Thermostat set at 68F and fan 24/7 for uniformity and comfort. - I could use the set back on the thermostat but since it probably will not make a significant difference, I keep it simple.

Bud, Still thinking about your stats. If you hook up two, you would not need a switch, just hook them up parrallel, which ever one turns on is in control. On cold days when you wouldn't want the downstairs to go below sixty anyway, that one would take over.

I had thought of doing two stats like that and even having both programmable. That would work fine at night as I could idle the one down stairs and let the bedroom one control the temp. That would solve half the problem. Now when I idle the one up and have the lower stat control the down stairs I would be sending up too much heat all day when no one is in the bedroom. That’s where I was getting stuck with just using stats. I started flipping the damper in the morning on my way down and that’s worked pretty well. kind of low tech.

On a temperature note this morning instead of being negative 20 it was positive 20 and I went out and it actually felt warm like I didn’t even need a coat to take the dog out. Figure out a way to save summer heat and winter cool and we will have something.


Edit:

I really don’t think I would need two stats to do what two would do if I set the down to say 60 at night it will keep the bedroom around 68 in most weather. That would be perfect and close the damper in the morning.

So you need a servo motor and a timer on the heat duct.
That constant temp you are talking about is underground, missile silo. There might be something available over in Bowling Green.

If every winter was like this one I might just be looking into a missile silo. Woke up this morning to a really nice warm bedroom and thought ut oh I bet its cold out. -9.9 f and falling still.

After getting ready for work I closed the damper on the heat duct 90%. Will see how cold it got today?

I hear the silos make a great house but look out with moving walls around. The government spared no expense with rebar in those 2 ft thick walls.

Never mind that some else has a missle pointed at it.

Well I survived about 2000 nuclear blasts in my life so far.

Not sure if you have seen this. Takes a couple of minutes to really get rolling. Growing up in the 50s and 60s was a lot of fun.

Woke up this morning to a nice warm bedroom and checked the indoor outdoor to find it was -13f again. The truck rolled over pretty slow and the snowplow didn’t want to leave the driveway as it was frozen in place. The gas gage was also on empty and I had to stop for gas and to my amazement no one was fueling very rare at that location about 10 miles north of my house. Looked at the time and temp sign and I knew why I was the only one foolish enough to be pumping gas at 5:30 am. It said -21f. Without any wind this morning I would have never guessed it that cold.
