OT: Boiler efficiency?

 Looking for tips on how to make our furnace more efficient. If I
lengthen the range between cut on and cut off for temp in the boiler
from 20 degrees (165-185f) to say 30 degrees (160-190f) how would that
effect the heating system? Would it make the boiler run less or more
efficient? We have a oil fired boiler with baseboard heating... Thanks, RMR

most efficient boiler is one that isn't running at all <grin>
the start up & shut down you have to purge the exhaust gasses & charge
the intake air... if you reduce the time spent turning on and off you
should cut back on fuel consumption... I've had better ROI on insulation
than furnace mods... ymmv

 
Yes, increasing the hysteresis would likely help efficiency slightly,
although with a boiler I don't know if it really matters much.  It
doesn't have the same system heat-up requirements that a FHA system
does.  Either way, I don't think you'll make enough of a difference to
tell when the bill arrives.

If you really want to make a difference, shrink-wrap your windows.
That'll knock a minimum of 20% off of your bill - even more if your
windows are crappy.
