have a Carlin 100CRD oil burner in an H.B. Smith boiler (series FD12 4 section).
The burner provides heat only (I have a separate gas hot water heater). During the summer the only thing the oil burner is doing is keeping it's water temp up. I hear it go on a few times a day for a short period.
In the past I have been told by 2 different techs that turning this boiler off is bad, I don't remember the exact reason but I just left it on as they recommended.
Obviously, being oil fired I can't ignore the cost of running it in the summer now, which was not as much a concern in the past.
Currently, the low setting is 160deg and the high setting is 180deg. Would it be OK to have these turned down, so that it is coming on less often and maybe for less time? What do you advise?
