Thats amazing getting an old boiler like that up and running again.

Nice one Derek... Glow worm boilers were our weapon of choice back in the day , the Micron and ultimate were basically the same boiler and we loved the micron as it would fit in a kitchen cupboard , I think the only repairs I had to do on these was replace the fan’s after a few years of good service due to the bearings over heating , other than that no problems with them... 👍

My Glow worm fuelsaver mk11 is 35years old 1989! Still works great. I service it yearly.

You got that up and running like nobody’s business! Well done. Great video. The amount of detail you go into is perfect. Thanks Derek 👍🏻 Asian Jon. Training.

Great video thanks Derek

We still have an Ultimate 100FF running the central heating in our house... any reason I should be looking to replace it?

[@jenlam4466]

I have Micron 50FF and would like to replace the radiators. Everyone says you might need to add pressure to the boiler but I assume this doesn’t apply to this boiler as I can’t see any pressure gauge?

[@martynlewis5901]

Don’t see many of these out there now, I have a dim and distant memory of fitting one around 2001/2002 ish. Cast iron boilers were built like tanks and would probably run forever with a little tlc every year.

Great video once again Derek..... Could we see how you replaced the olive and the insulation panel too?

[@tomkatgastraining]

Sorry it’s in the scrap yard now 😁

[@paul_my_plumbs_uk]

Could you do some LPG videos please Derek on the vids to do list 🙏🙏🙏 and don't forget to stop waffling and get on with it 😂😂😂

[@tomkatgastraining]

Will do 😜👍🏻

[@wulliest]

That boiler looks so much less fragile than a modern condensing boiler

[@tomkatgastraining]

Yes mate they are bulletproof 😜
