Since this is a central heating thread.... :)

I try to turn the thermostat down at night to save energy (and money). But this old house has some leaks, and the temperature drops fast inside the house.

So, the unit seems to cut on and off just as many times during the night when it's set on 63 degrees compared to when it's set on 72 degrees during the day.

Seems to me there is no benefit in cutting it down if it's going to run just as much as normal. I might as well leave it on 72 and be comfortable.

Is that right? Any heater guys out there who can answer?

Thanks in advance!

(And just as a side note, I have fixed what leaks I could by adding sealing tape, etc.)

I am no expert but we live in an old (over 100) house and one year we went crazy with the caulk and sealed up every crack and crevice. We decided to close off all the upstairs registers. It was a mess. The windows developed condensation and ruined all the trim paint. Some of the caulk on the storm windows has been taken off and I enjoy the cracks and crevices again. We have insulated windows and the house itself is well insulated. That is enough in my opinion. A house has to breathe. Interesting when people were not so concerned about a 'tight' house I don't recall radon being a threat. Wonder if there is a connection?

As far as temp in the house. Where is the thermostat in relation to the heat runs? It makes a difference as to the heat in the entire house. One room might be warmer than the other and if the thermostat is close to a heat run it may not be accurate. We don't go by temp. We go by if we are warm or not and we don't do the up and down thing. We also run the furnace fan continuously.
