expansion vessel

I'll post the cliffnotes before as it turned into a somewhat long post: * boiler died end of last year * housing had everything replaced (regular boiler) this time last month (January). Baxi Solo 15HE installed. * red expansion vessle/tank fitted (attic expansion tank shut off i think??) *...

Hi all, bit of a novice on this but here goes. I have noticed that the Tundish is dripping constantly alongside my Tribune HE cylinder. The Central Heating and Hot Water system are working fine it appears. There are two expansion vessels above the cylinder one small red one with the pressure...

Hi I have a Linea 730 Vokera boiler that has code 4 on the display (low pressure). When I top up the pressure water leaks from the top of the external brass part on the pump next to the hose leading to the expantion vessel. For the last few weeks the pressure has read 0 yet the system has...

Hello i repressurised my expansion vessel with water to 1.5 bar heating put on this evening the gauge is going up to 3 how do I reduce the pressure as I am a bit concerned it is to high, is it just a case of bleeding a radiator to let out water? Tim

Hello, from a new member i have a new build property, the ch system has an expansion tank on the top of the water cylinder I have a few questions 1. When the system is off the gauge says 0 is that right? 2 when the system is on it only reads .5 as a maximum pressure 3. I need to refill the...

hi guys. This is maybr a sizing issue but thought i would put it to others to get a second opinion. Went to service a boiler the other day then afterwards noticed that the water pressure was down to almost zero (sealed system) i repressurized and checked all rads were bled . All fine. left...

As above really. Vessel is leaking. Have had one quote stating boiler must come off with a suitably high number attached followed by a suggestion that it might be better just to fit a new boiler. Have also seen 2 plumbers of this parish say that its not that bad and can be done in situ in 2-3...

Hi all, I've got an Ideal Response boiler, about 10 years old. I tried a search on the forums (and google) but haven't found an answer to my question. It's been in contract with British Gas Home Care for much of that time, and over that time I've twice had them out due to faults that turned...

Hi I went to a job to change a zone valve but noticed that the htg pressure vessel was on the flow after the zone valve. The system has twin zones plus hot water , should i change it and put it on the return? I know it will probably be fine but abit worried if they turn off all the rads and...

ive fitted quite a few boilers now but would like to get a bit of experience with fault finding, ive a customer with a boiler that when you get it to 1bar, it heats up and works, but then goes up to over 3bar, blows off, and when cools drops to about half a bar, is this going to be the expansion...

i just bought a worcester camray 18-25w utility boiler would the expansion vessel fitted in the boiler always be the right size for that boiler many thanks:vanish:

Is it possible to change an Expansion Vessel on a Boiler without draining down the system, is it possible to clamp the Flexi Pipe without damaging it?

Hi all usual symptoms; Pressure ok when central heating off, shoots up to 3 bar when central heating on with usual water out of external pressure releif pipe! Been told its Expansion Vessel that has failed! Trouble is on Worcester Bosch 23i Greenstar Juniour, expansion vessel is part of...

Got called to a customer today to look at an open vented system that had been converted to sealed a good few years ago. The old guys system has been running at a constant 3bar+ of late, and the PRV is constantly opening as a result. Suspecting that the expansion vessel was the the fault I took...
