had a new Glow Worm boiler installed last week, we have a twin zone system (seperate ground and first floor heating) the ground floor will not heat up over 15c???.
The room stat is ok.
The motorised valve opens on demand
Is the boiler wired up wrong somehow?
first floor will heat up to 20c+ with no problems
