does turning a thermostat all the way down during the winter damage the boiler?


Common sense ignores realities of human behavior. People forget. Or have other things on their mind instead of remembering to turn off the lights or set back the thermostat. Should they avoid spending $10 to get a thermostat that does it for them?

Setback thermostats work best in commercial environments...when there can be 12 hours or even weekends where the space goes unoccupied. But it's never made any sense to me to turn it down for a few hours, then turn it up for a few hours, and over and over again.....what's the point?

So stick with what works for your house, with your furnace setup and local weather. What works there, however, may not work as well elsewhere. The key is being open-minded enough to recognize that not all solutions work everywhere. And that this means some things can and should be used elsewhere. One size certainly doesn't fit all.

But as to your question, small percentages of energy savings DO ADD UP. The little bit here and there can do a lot to help reduce pollution and use of fossil fuels as a whole.

Thanks How,

The furnace does not, in fact, have a bypass, the basement is often 10 degrees colder than the rest of the already cool house, and some of the radiator pipes run through a barely insulated garage, so all of your explanations seem to be on the mark leading to the potential scaling/condensation.

As far as the new programmable thermostats go, I like mine, it was a snap to install, but I don't think it has changed my energy usage at all. The reason is that I have a single zone in my house, live alone, and always keep the heat on 57. I agree that they can save people money, more so in industrial use, but just being mindful is the best way to sip energy. (that and putting on a sweater as Carter suggested

What can be done is wire a thermostat in parallel with the main stat, but locate it in an area which is subject to freezing. A low temp thermostat is available for these purposes, often referred to as a "freeze stat" It's purpose is to run the boiler in the event the temperature gets within a few degrees of freezing...for example it could be set at 40 or 45 degrees.
