Gentlemen good afternoon
Bit of an awkward one. Last year my nan had a new boiler fitted and system converted to sealed. Now for the last few months my grandad has had to top boiler up on a daily basis.
His local plumber is a bit of a cowboy and is trying to charge them a lot of money to change their cylinder (reckons the coil has split). I have said I will go up next weekend and change it if this is the case rather than them pay a lot of money. Trouble is they are in Kent and I am in Bournemouth. I want to be sure it is definatly the cylinder that needs doing and it's hard to talk my grandad through the possibilities on the phone.
He he has inspected all pipework for leaks. Checked expansion vessel etc all fine. He is convinced coil is split.
However if if this is the case I would expect the CWSC to overflow as the water builds up. Also I would expect hot water to be discoloured. He says he hasn't noticed any of this.
Not sure what Vailliant it is but am waiting to find out. It keeps going to f23, which is flow and return differential temps.
Does anyone one have any idea what else the problem could be or is it most likely the coil?
sorry for being vague but without looking at it in person it's hard to find the problem.
Cheers
