Advice needed for a hissing leaking Potterton

[neffany]

I am a boiler novice so bear with me. This boiler is a Potterton Statesman Flowsure which seems rather old! When I moved into this house my father in law rebuilt this boiler so I didnt have to buy a new one. There have been a string of problems with it and I'm at my wits end.

The latest thing is when I turn the heating switch to constant, the temperature goes right up to 120 within a few mins while hissing alot. The pressure drops so i added some more pressure tonight which equalled alot of water pouring out from underneath it.

It has had many dramas when I have asked it to provide me with some hot water and overheats alot. It has had many new parts put in by my father in law and he has come to a dead end as to why there is no pattern in the boilers actions.

Please can someone advise me before I consider buying a new boiler.

Thanks

The obvious answer is to call back the boiler engineer

Otherwise check the pump

The problem with these is that when anything needs changing everything else starts to leak........as Agile says most likely the pump not working causing the prv to blow

father in law says the pump0 has been replaced and you can hear it working

Just turned boiler on again, cant hear pump working, temp goes straight up, hissing and leaking. Engineer coming on Tues

Possibly air in the Heat Exch I am afraid that the Statesman Flowsure is without doubt the worst oil fired combi ever made, many have been ripped out prematurely, I would sugest spend as little as possible on what is really a dead horse, A Grant Vortex Combi 26 would be a good replacement boiler, more efficient and good quality
