Boiler installers never put daily "set back" thermostats on boilers,
only forced air systems get those, and they tell you to set the
thermostat once and leave it there.

Why did you assume the Mormon had a boiler?



The rules are completely different for radiant heated buidings vs air
heated buildings.

In an air heated building you heat the air, in a radiant heated
building you heat the building materials and that in turn heats the
people. *When you lose all that stored energy it costs a fortune to
recover it back in boiler usage.

It costs that same fortune and more to keep it hot without
interruption. *Maybe it's also unpleasant becuase it takes hours to
heat up, but that's another story.



There is nothing quite like the
warmth of a radiant-heated house.- Hide quoted text -

Hot water heat is very popular here.
