Glow Worm Boiler Frost Stat Kicking in Early Help and information on all topics relating to your central heating, air conditioning and ventilation issues.

Hi, i have a Glow worm Ultracom 30sxi boiler & the onboard frost stat is kicking in early. I realize the pump should kick in at about 8 deg & the boiler should fire up around 4 deg, But my boiler is firing up at about 7 to 8 deg which is going to cost me if this keeps up. Has anyone had this problem or knows how to bypass it as i did also fit a frost stat on the system that fires up the boiler, but i also put another stat on the return pipe to shut it off when all had warmed up to save fuel.
