I have Glow-worm Iconomy Plus boiler 6-7 years old and fully pumped S Plan system about 30 years old.
I have 5 radiators, one of them is nearly cold.
Recently my boiler got noisy and I've strarted reading different forums in order to sort this out. Last night I tweeked with the bypass cock, I closed it and then opened it a little bit (something like half turn) My boiler got noisier but the cold radiator became relatively hot.
My question is: is it OK to leave the bypass cock like this. If not, is there some general rule how to set it (I cannot remember the position it was before).
Also I guess my system has a lot of sludge and scale thus I plan to put some de-sludger and then drain. Should I tweek with the ballance again after this?
Thanks
