Heating’s been foobarred since before christmas. Managed to get it running by running hot water on constant and turning it on full. (water is now scalding hot – not good with kids in the house)
I think a valve is sticking but I’m not sure which one.
any ideas?
BTW – It’s a 2 zone system (upstairs/downstairs) with a glow-worm boiler. Thermostats are working ok and I think the Grundos 15/60 3 speed pump is working OK too (thank fook for heating forums)
Merry fookin Chrimbo !
