[@Carl-re6zb]

Thank for sharing mate.. The tip about bracing the return pipe and chassis is appreciated as it's always the bug bear when changing the hex. Top man and keep up the great work.

If you are not qualified you should not be even taking the cover off the boiler.

Always good to have a go at gas, what could possibly go wrong?

What was the reason for changing hex

[@Stu_Gilbert]

Top video dude 👍 nice one

[@jmqmin]

Fantastic video. Can I ask, what was the reason for changing the heat exchanger?

[@theriac.]

Great video. Can you tell me how long it took from start to finish? Thanks

[@Martindyna]

Nice video. Apart from a leak are there any other reasons to change out the main heat exchanger ?

[@charliewillis8527]

It amazes me why people take them out much cheaper to repair iv made a tool to remove the bottom baffles but had one yesterday cleaned it as best as i could but couldn't get the botto. Baffel to drop right down so had to replace the heat exchanger

Legend pal

[@plumberdan5720]

Great video, when you staining on the top of the junior kebab heat ex is it due to the red burning seal failing or the heat ex leaking heating water? Everyone says different things?

[@grannyring]

Heat exchanger water seal failed nothing to do with the Red burner gasket

[@plumberdan5720]

@@grannyring thanks for your reply, some engineers say that and others say its the red burner seal leaking POC

[@Carl-re6zb]

Water leak around the rim of the hex causes 'crusting' usually caused by poor water quality. Leaking seal will probably be 'reddish' in colour. 'Kebabing' usually caused by low water in system , but not dangerous. Just dissimilar metals causing rippling. If in doubt, just test around top of hex with a gas sniffer or analyser probe to determine if 'poc' escaping.

[@Carl-re6zb]

Water leak is AR as no 'poc' but requires renewing. Can be left on until new part fitted Leaking seal causing 'poc' escape, is AR or ID. Needs to be isolated until repair done.

[@grannyring]

Water leak is AR you sure about that ! Usually down to poor water quality overheating and run dry from a failed or neglected expansion vessel

[@micmac69]

I think unless the baffle has been removed after a couple of years then are a sod to get out!
