: the thermostat do that ? I installed the thermostat myself. It's a aube digital thermostat and I think that what it does is simply turn on the boiler burner when the temp dropped and turn it off when it reached the desired degree no ?
*** Yes, that is what the thermostat does (again and again.) Therefore if the room is heated enough by 140F water, the burner shuts off and the water only reaches 140F water.
: Before there was a honeywell round thermostat installed, could this thermostat do more than turn on-off the burners ?
*** Probably not much more - depends on what it is wired to.
: Do I need to bother, is it more energy efficient to run the water less hot when the outside temp is not so cold altough the burners might burn longer than if they were set to a higher degree ?
*** Yes, it is more efficient to have the water just hot enough to do the job.
Now tell us what control you have that sets the water temperature. What is it you are playing with? If you have a high limit control, that is a safety device, not an operating control, and you shouldn't be moving it.
