Noisey Isar 30100 when the pressure jumps

[jaseypoo]

Hello, I wondered if you could help, can the expansion vessel on an isar 30100 be re-pressurised , my local boiler company says not, the only boiler in the world apparently, my boiler makes noises, sometimes loud bangs, this is at the time the pressure randomly increases from about 2 bar to 3 bar. They said they need to put more air in the expansion vessel, but there is no way to do it and I should get a new boiler. bearing in mind the bolier is 4 years old. I have tried ringing ideal, but cant get through to anyone. Can you tell me how to do it, if they need any special tools etc.. Many Thanks

get another opinion mate

Mind you I seem to remember that it is a bit of a get to the valve

Something to say for getting a new boiler, despite the name, it is not ideal. However, I have never heard of a boiler with an expansion vessel that can not be pumped up. even if yours is impossible to rectify, an external ev is fitted easily enough.

Ben is perfect right

if you have the room its easy

Thanks Guys I have had a detailed replt from Gas4you, apparently the fan has to be removed and then the valve is accessible, some companies eh, easy to say get a new boiler eh...

I remember now

doh

that gas4 is rather good you know

hi ive worked on lots of ideal and one of the models it is imposable to refill the expan vessal best op is cut in a remote bottle (they altered the the position of the vent from top to the back behind gas vaule so u can recharge)if vaule at top u cant get to it

WHich one daden?

I have not see one yet

And there was me thinking this post was finsihed, im interested to see where this goes, keep it up guys
on a vote Valliant or baxi?

 

[gas4you]

Vaillant, but I'm biased

sorry gas not sure of model no but it was funny because i was with ideals senior eng at time and did he feel a **** a we was having so many problems with the ideal my god they are sh** i still have about 20 pcbs in loft for the m80s

The engineer sent to me by home serve has just spoken to Ideal technical and they state in order for the expansion vessel to re pressurized the boiler has to come of the wall as it is not possible to get to it by removing the fan. It is apparently fixed the to the rear casing behind all other components, so might have a new vessel fitted inline.. Another fantastic reason not to have an Ideal boiler.

i've neva had to repressurize 1 yet, but hav been told on some models theres a hole in the back panel of the combustion box to get to the valve. but apparently ya neva can get to it either hav a remote 1 fitted (not a big job) or have the boiler took off the wall and replace the existing 1, mind you if ya doin that id change the boiler while its off!

for the time bein ya could repressurize the boiler to 1bar and turn ya stat dwn slightly so the exspansion is not not enuff 2blow off..

wa jus thinkin, does it need a new prv aswell? cuz they can be a bit tricky n all!
