wow, I thought this post had died a death!! I paid normal over the counter prices, for someone in the trade buying regular then I'm sure they'd get a good discount!! I don't rush a job, particularly if I've never done it before. The plate exchanger wasn't a direct swap and required some pipework...

That's sounds like half the workforce!!! The other half are pot bellied bald headed geriatrics.... I'm not sure which category I fit into??!!

I've just come off the 12 hr shifts but don't know the chap. Mind you, I'm stuck in outpost better known as B Site... Anyway, how dare you suggest we drink tea and sit down all day!!! I'd have you for slander..... If it wasn't true.....

Jftr, my day job is sticking jet engines together....it pays the bills... ;-)

I've spent maybe 10 hours in total on it and nearly half of that on the diverter valve issues. I'm neither expert nor engineer so took great care and time to not rush things. I paid public prices for the parts when trade get them alot cheaper. Someone who does this for a living on a daily basis...

:lol: Sorry old boy, you couldn't be further from the truth. He spent all of 2 mins looking at the boiler, diagnosed a faulty gas valve and a quote of £300 to change. He also said it would be better to change the combi than repair it...

Well, the corgi (gas safe?) guy I called out didn't want to fix it. I dont like to waste peoples time so I fixed it myself...

A medal would be nice but I'm happy with the satisfaction that I doubt that any heating engineer would have gone to this length to save an otherwise good work working boiler... :D

I've spent the last two days working on my Worcester 280 combi. The symptoms were hot/cold DHW and occasional tripping out. I replaced the secondary heat exchanger for a plate exchanger (a Worcester upgrade) and put a new expansion vessel in. I fired it up last night and CH was good but had...

Diverter valve is ok but noticed the expansion vessel is completely empty...is that good or bad? I'd have thought there'd be some water in there!!

The original was a white bottle type but the replacement is a plate heat exchanger. Apparently this is a more efficient upgrade. The kit comes with plate HE and associated pipework required to fit this mod. The connections are correct, the thing virtually falls into place and all looks good to...

I've just changed the secondary heat exchanger for a plate heat exchanger on my Worcester 280. I also changed a u/s expansion vessel as the bladder had perforated. Initial testing proved good (see previous topic!) but just found a bizzare fault when drawing hot water. Previous topic...

New plate heat exchanger and expansion vessel fitted and under test as I type. A few strange noises and a couple of leaks at first but all now stopped. It seems to be working better already but i'll need to address them leaks! Edit: There's a rushing water sound, not too dissimilar to when a...

I've got the expansion vessel and HE out. Something tells me water shouldn't flow out of the schrader valve?? :?:

I've not noticed it rise when cold but tbh the heatings been on most of the time! I know what you mean about the plate exchanger, the mains pressure is higher than the system pressure . Perhaps the hole/crack is small enough that at cold it's sealed and only opens when heated? I'm changing it...

Hi folks, further to my recent post (suspected faulty gas valve and scaled/sludged heat exchangers) I've run a sludge remover thru the system but noticed the pressure does not return back to the previous pressure at cold. I've reset it twice now to 1 bar (filling loop is off!) but when the...

Thaks for the confirmation, I couldn't get my head around adding a cleaner to dirty water! Any comments on my drain/fill method? I'll be draining it fully at a later point to fix a slightly wet joint but didn't see the point of draining it fully just yet til I'm ready to do the work...

I wouldn't add Fairy Liquid to dirty dish water so for the sake of an hour or so it can only get a bit cleaner? :wink:

I'm looking to run a sludge 'remover' to my combi system before changing the secondary heat exchanger and had this idea in mind: (Worcester 280) Put hose pipe on a down stairs drain point and open. As the system empties open the filling loop to replenish as it drains to minimze air locks and...

Hi folks, sorry for the delayed response! I've checked a few electrical connections and the burner seems to ignite fine now so £300 on a new gas valve would have been a bit of a rip off I think! I've had a search on here and a bit of a google and I think i'm going to have a look at the secondary...
