Hi all,
I have a Swiftflow 125e glow worm boiler which Supplies bucketfuls of
steaming hot water in the winter but during the summer it can be too
hot. There is a potentiometer on the control board that can be used to
limit the burner gas pressure. Would it have an adverse effect if I
reduced this setting to limit the heat output of the burner. I am
hoping this would safely turn my boiler from a 125,000 btu to a
100,000 btu unit or less for the summer months then allow me to turn
it up again in the winter.
any advice from someone with experience in this area would be much
appreciated.

cheers ian
