I would like some advice as to our way forward. My daughter has a system gravity fed boiler and the 10 rads were not warming up and hot water was luke warm.
Her neighbour popped in and said there was hardly any heat on the return ( flow ok ). he kindly cleaned out the magnaclean in the air/cupboard which was a little grimy but not too bad.
She contacted her service company who sent an eng out who said the boiler was overheating and considering its age she needed a new one. He felt it unsafe and switched it off with a sticker.
A surveyor came round, agreed with eng, but said as the existing flue fed out into neighbours area it would need to be moved to the other end of kitchen. He gave a price which she accepted, and pre install paid.
An eng came around and said existing position ok, and went ahead with instal and completed the job. (Ideal Logic H18) resulting in exactly the same problem, return cold.
Another eng came round and repositioned boiler to survey advised posn. Still the same problem.
Return visit and eng converted system to pressured. On setting to 1 bar and firing system up, within 5 minutes there was a pop and a pipe burst in the ceiling above.
Return visit, repaired pipe and changed the 2 pumps in A/c ( 2 zones )….no change !! At this point he cut into the return pipe 3mts from boiler and said its full of sludge and the floors would need to come up for a re pipe ( which isn’t covered by her contract ) so no more they can do.
My Q is, would a powerflush be the best next step to avoid floors up ?
And, when the boiler was installed should the system have had some form of pre flush and any issues been discovered.
This is up to date, and has been going on for the last month. A new boiler, a big hole in the ceiling with 2 kiddies and no heating. Any advice really welcome. Thanks.
