Mega Flow with damaged baffle -

[Dannypipe]

Had a job booked in today to change a pressure/temp relief valve on a indirect Megaflow cylinder.

When I took the old valve out, I was careful to keep the probe under the baffle plate so I could feed the new one under it too. However something didn't look right about it, so I pulled the valve out completely and felt in the hole with my finger.

What I felt can only be described as waxy, it was white and broke away. I fed my small camera into the hole to take a look inside, but it was hard as the steam kept fogging the lense.

Anyway I'm fairly confident that the baffle has totally degraded, which would explain why the temp/pressure relief valve was weeping.

Has anyone else come across this. I'm going to call the manufacturer tomorrow to see if its covered in the warranty.

If not it's either a new cylinder, or I may drain the cylinder, take out the lower immersion heater and hoover out all the bits and bobs, and then fit an external (white) expansion vessel.

Any thoughts appreciated, sorry to have gone on a bit!

I don't know if what you say may be the case Danny but there is definitely a big problem with megaflows loosing their charge in a very short period of time.
So much so i refuse to use them anymore and fit anything with an external vessel and have fitted lots of vessels to existing ones.
It would be interesting to hear what they say but i doubt they will admit to a problem.

I have been using Range Tribunes or Ariston Primo's for the past few years. No problems with either one. Both cost around £550 + vat for a 210 litre.
You can get the Tribune prepiped and wired too which can save a bit of time.

ARGH, just wrote a long conclusion to this thread, and when I clicked 'post' it messed up and I lost the lot! So I'll retype the main points.

The guy at Heatrea Sadia said that the 25 year warranty didn't start until 2002. Before that it was a ten year warranty.

So I'm going to cut in an expansion vessel. They advised me that this is ok, and gave me the correct size for the cylinder.

Still I think MegaFlows are over priced, and I'll continue to fit Stelflow in future. Less than half the price and my merchants always hold a good stock.

Cheers for the answers,

Danny

I've fitted a few Stelflows now with no problems.
