I just moved to Idaho. Night time temps have been well below freezing. The house is fairly well insulated. Heating is via electricity, there's no gas in this house.
I normally keep the inside temps at 73 degrees; at night, I turn it down to 60 and have electric heaters in each bedroom to save money.
Is this correct? It seems that it could go either way, since I now run the house heater for a long time to get the inside temps up.
So: do I save money by heating the house from 65 to 73 every morning, or should I leave the house temperature at 73?

Same boat, max temp in house is 65* in winter. Baseboard heaters throughout.

We average out for the year at $120 for electric. 40 summer / 200 winter est.

I live in a town where the city buys power from the local grid, then bills the citizens. They make a deliberate effort to keep the power affordable for us! Our realtor told us that last year, the highest power bill was $200  a month.

The previous owner apparently did the same thing, as she had electric heaters in every room.

You absolutely save money by turning down the heat at night and when you leave the house.

The thermodynamics of it is:
- heat lost to the outside is a function of the temp difference between in and outside temps
- the closer your inside temp is to the outside, the less heat is lost

Even power companies used to say "set the thermostat and don't change it", but they are 100% wrong.

My house has 2 pellet stoves on thermostats... one in the master and one in the FR. I turn them both on in the morning, then turn on the central air to "Fan On" so it spreads the heat evenly. Stays like that until we go to bed. Wake up in the morning and it's a cool 61 degrees. Temps here at night have been in the low teens to upper 20's...

If we need more heat, we do have central heat, but it is propane. Our power comes from our solar.

I have hot water radiators. Just turned it on last night for first time.

It's an older boiler with big cast iron radiators.

I took out the radiator in one bathroom for a remodel. Will replace with a small baseboard heater.

House was down to 64 after several days at about freezing.

Turned it on 70 ran for.abot 75 minutes. They are still warm and has not run again

So we leave it. Has stays even and.no long runs

More than 3 or 4 degrees difference and you use more fuel/electricity re-heating in the morning than you would have maintaining overnight.

First house with hydronic heat. I'm loving it, cause wifey can't jack the thermostat up and down (well, she could, but the lag is so long it wouldn't do her any good.)

Principally gas, with electric to run the boiler and the circulation pump. Supplemented with a wood stove, so far it's pretty amazing. Zero sound...wake up in the morning and the temp is exactly what it was when we turned in, 72 in the great room and 68 through the rest of the house.

Be careful with supplementary heaters until you know the cost, OP.

CSB, SSgt in GK (Germany) with a wife and three young kids didn't budget to fill the oil tanks under his house (common to GE houses, average about 4K liters of heating oil - and they take cash on delivery). He went out and bought four of the roll-around, oil filled, plug in radiators that kept his house nice and warm. His quarterly electric bill came in...it was 3,000 or 4,000 Euro. He was a good guy and went to the boss and told him the whole story before the collection people came to the AF. The officers took up a collection and paid it.

A couple degrees is fine, a 16F temp change means for a LOOOOOONG heating cycle time and then many shorter one's to reheat everything in the entire house plus the air itself. Turn down the high temp of 73 to 70, get proper humidification to be more comfortable and drop night time temps to 66-67f and save yourself some $$$ and be more comfortable to boot.

Welcome to idaho. Yes, you will save by turning it back at night. I keep mine at 63 during the day and 60 at night. Eastern idaho at elevation gets cold. Typically burn 3+ cords of wood to supplement propane.

Our furnace burns natural gas.

We set the thermostat at 74 degrees in the daytime, and turn it down to 70 degrees about 7:00 or 8:00PM.
No need to have the house at 74 degrees when we are in bed sleeping.

I prefer 60 at night, otherwise it's too hot. It's regularly negative temps at night here. All the energy money is spent during the winter since there's no need for air conditioning.

I explained it above, but you can look up the equations:

Q=hA(T2-T1)

See that "T2-T1"?  That's the temp difference between in and outside.  The higher the difference, the higher the heat transferred to the outside (Q in the equation above).  It's that straightforward.  The closer your inside and outside temps are, the less heat lost to the outside.  That heat being transferred is supplied by your furnace or baseboard heaters.  Money.

Except that isn't the whole story.

"Reheating" your house isn't just heating the air. The things in your house have all have a temperature.  The walls, the floor, your mattress etc etc.

When you bring a house from a cold temp up to a much warmer temp, you will notice that your heating system has to run through many cycles in fast succession.  The air will come up to temp and it will shut off. The air will drop quickly again and it will need to heat cycle again.  This will happen several times, with longer and longer periods of time between cycles, as the air slowly heats up all the materials within your house.

The counter argument is that keeping all those things at their "normal" temp, not just the air, is more efficient than reheating them.

I can't stand forced air heat.

If left to my own devices, I'd leave the house at 62, and bump it up to 67 in the morning for showering.  Girlfriend has different ideas.

Electric blankets and a cold house are pure bliss.  Again, girlfriend has different ideas.  Cant put her ass on a cold toilet seat at night.

Electric heat and keeping it at 73°? Might as well burn money.

I like 67-68° personally.

You would sav money by not having the house at 73 degrees. I would die bring that hot. I have three 95% efficient gas FAF's and they stay at 62 in the winter.

Except for a small wood burning stove, I heat my house with electric as well.  However, in the winter my house is usually between 53 and 56.  When it gets to 50, then the stove has to be fed a few times a night. The two electric heaters cannot keep up with outside temps around zero.

The greater the temperature difference between the outside and inside the faster heat transfers.  This means that when trying to heat the inside too much, your energy costs will go up.  But, by the same token, if the interior stuff (thermal mass) has been allowed to cool to well below your comfort level, it will take that much more energy to warm things back up.  It is best practice, then, to try to maintain the inside temp to the lowest where you are reasonably comfortable.

I'm not sure how to convince you, but heat lost is heat lost.  Your argument isn't factually true.  Don't trust me?  I can send you the email address of my two thermodynamics professors.
