> I programmed it to run as close to 24/7 as I could, because that way it uses the lowest flame, which is the most efficient flame.

The energy loss from your home increases as the differential between inside and outside increases, right? So at night or when you're out, if your house were kept colder, then you'd lose less energy to the outside.

So by keeping your heating running 24/7, you're wasting some energy in the extra energy loss when you're out, right?

How does this compare to the efficiency gain by running your more efficient flame? Have you calculated or measured that you actually save energy overall?

Yes, but I can't let it cool very far, so it's only a small energy saving.

> How does this compare to the efficiency gain by running your more efficient flame?

The boiler can be up to 98.6% efficient at low flame, going down to 86% at full flame.

And after experimenting it always ended up at full flame when trying to rewarm a house.

I tried, but I couldn't, winters are just so variable. I even emailed the EPA asking if they had research data, but they didn't.
