Still got my old Baxi back boiler installed in 1976. Still working. Just in the process of changing it to a modern boiler. Not a lot to go wrong with the old back boiler as long as it’s serviced. But heho, let’s get into the 21st century. Don’t even know why I watch your videos (as well explained as they are) as I’ve just retired. 😂😂 Keep up the good work for the next generation.

Same here,I retired 2 years ago. My elderly mum, still has a Baxi back boiler installed way back when I was a lad.(1971?) My brother manages her care now as she suffers from dementia.

Great video. Love how clearly you explain it all. Only ever come across one and ended up taking it out.

Turned off a 1969 Baxi BBU last week AR, The customer had a conservatory built 6 year ago vent bricked over it passed f/f and spillage no signs of soothing actually in really god condition like new, Customer said other engineers have been and never issued a notice or mentioned ventilation nor did they go in the loft, I really wonder how these guys sleep at night.

Really well explained be interesting how you work on a baxi Bermuda back boiler

[@tomkatgastraining]

Love the baxi Bermuda so easy to work on and you knew it would go back together again

My own boiler, not a plumber/gas fitter, is a Worcester 9.24 electronic open flue combi. 1989

Gravity circuits! Hot water dose wat.... lol

[@simonwalton6856]

I'm a bit confused there because surely what you've done is the same test twice , because you put the smoke in the same place, one with the alliance not running and one with it running? Shouldn't the flue flow go at the base just past the burner at the start of the primary flue?

[@tomkatgastraining]

No you test at the draft diverter not at the burner. The flue flow and spillage are different test like I say in the video
