At last a helpfull fellow.. thanks... I wouldn't convert anyway.. But i can not find anyone who wants to pressure test the boiler, everyone local is a worcester man and only wants to change the boiler and will not give me 100% guarantee that it will cure the problem.

Ok bengasman, you seem to have all the smart quips but no answers, one of the over-priced plumbers who talks a good job but does nothing. I have used only corgi registered plumbers/heating engineers and too no avail have a useful answer, I will solve this myself as people like bengasman are...

What would be involved to do this...? thanks

Useful mate.. thanks. Ask a simple a question, get a simple answer..!

Checked all major joints and can find no , leak, no crusty joints or anything. Only one rad valve showed signs of not being like new, changed and problem still here..! The house and all the system are only 8yrs old..! As mentioned all boards up and no sign at all of a leak. My plumber/s have...

Back again. Recap: Megaflo H/W cylinder , Ideal boiler Minimiser SE 9 yrs old. Story so far and 3 plumbers.. and about £120 quid down. Start December system started losibg pressure one day. Will lose 1 bar in 2hrs when boiler on.. Diagnosis 1 - Autovent - Changed Diagnosis 2 - Pump -...

Cheers. Re assuring..! how can i prove that this is the case, is there any way i can test this, how much water would you expect to be discharged from the condenser outlet?

Here again.. Boiler Ideal Minimiser SE with megalflo Water Heater. System as been losing pressure, ever since the pump was changed early December. Local engineer changed pump (grundfoss selectric), one week later we stared losing pressure, same engineer said it was pressure vesse, so we...

Yes that is correct, must be a leaky shrader valve?

Boiler is an Ideal Minimiser SE (8yrs Old), Cylinder is Megaflo, Vessel is RWC 8Litre pre-charged to 0.5bar.

Pressurizing the Vessel. But. I have had a bucket on the discharge pipe and have collected no discharge from the PRV? I did think the local engineer was talking ****, So much for recommendations, I think I will get a new vessel and try it for the cost? Presume you buy them pre-charged.

The systen pressure was 0 when I checked with footpump c/w gauge. Also air is escaping when I remove pump. Presume valve as gone. Would this account for pressure loss in the system? If so wheres all the water gone i've been topping up with the past 2 weeks. Local engineer says CH coil could be...

Continued from my last post.. (no more replies) Unvented system losing pressure..! I have checked with car pump pressure of expansion vessel = 0 bar, when i blow it up, the gauge on the pump slowly fals back to 0 (sytsem pressure acording to RWC (maker) should be 0.5bar). Could the fault be...

Ran boiler on CH for 2hrs last night, but turned off when system made a "low whining" sound not quite a whistle..! After the boiler was switched off there seemed to be a "low gritty" noise flowing through the pump"? Switched everything off and left overnight... This morning checked inside the...

Not the boiler that banged. she's paranoid about the CH at the moment. There are no isolating valves on the boiler so hence can't test it. Chris R. what did you mean when you said "try high pressure" I took the covers of the boiler but couldn't see anything out of the ordinary, would any leak...

Missus just rung me at work, says "the boiler went off with a bang..." Sounds like a new boiler to me. I'll let you know the whats happened when i get home...

Thanks Chris R. Is there anyway I could prove this. I'd rather just know for sure then get the whole boiler changed for a Worcester or a Valinat. Is it commercial sense to get the Ideal stripped and repaired if it is leaking. Is there a test to prove the leak is within the boiler itself. Thanks

Hope someone can help. We have an "Ideal Minimiser SE" Boiler and a Megaflow Unvented system. This has been working fantastic for 8yrs and the boiler serviced twice in this time, (last time engineer said everything was fine and did not need doing!). At the begining of December the boiler tripped...
