Glow Worm 18R was fitted 6 months by a plumber to replace the old faulty Glow Worm.
Had ongoing issues with central heating coming on randomly but cannot control it using programmable timer or room stat.
Initially the plumber sent me out to pick up a hot water cylinder stat then a programmable timer which he said were also giving intermittent faults.
eventually it seemed to only occur occasionally so we left it but now it is constantly on and has been since yesterday and the house is roasting
the only way I can stop it is by turning off the main switch that seems to cut power to the whole system
that then means no heating at all
I do not want the plumber back as it has become embarrassing (and he is a neighbor) making it awkward
everything I’m reading online points to either faulty frost stat in boiler or incorrect boiler wiring.
Any advice (before I can get another heating engineer out next week) appreciated
