combi 90 , worst boiler ever?

[tamz]

First time I've serviced the thing.

Next year if I do it I'll make sure I've got scalebreaker with me.l

Ye can get them out with a toffee hammer. A wee dunt and they come out easy enough depending how they've been running right enough. I'd one that took me a good half hour to pull them.
On the bright side , at least you can put them back in.
It could be a warmflow. They come out no problem cos they are melted away lol

Combi 90 sounds like a warmflow. Money on not enough expansion. Same with most leaky sealed systems. Lack of maint or p poor installation.

Nope. Worst boiler ever was the Myson Midas B.

Are / were they the ones you made least money out of?


Or are they the ones that Plumbers dumped on your counter and said

" I want a warranty replacement" - yes, the entire boiler

In fairness, it was a gas boiler - when I posted I missed the fact that this was the oil/solid fuel forum. The Myson Midas B was an experimental combi back in the late 80's - it was the first to use twin pumps instead of a diverter valve.

Cutting edge technology back then! I sold 36 of them onto a local site, and 34 of the 36 failed on installation. The Myson engineer more or less lived on site for about a month.

Oddly enough, the fan flue version - the Midas SI - worked fine.

Buderus have to be right up there with the worst. I remember fitting them for southampton city council. They were packing up quicker than we could fit them! They decided in their wisdom to stop using them and started fitted isars instead!

if you want stupid baffles, try getting rayburn ones out with just a length of steel wire to do it with, has to be the most stupid design!!!!!

 

[Roger Welton]

and the oil nouvelle ones that crumble as you try and encourage them out, tapered baffles into a tapered opening, there's an idea
