Best combi to work on from a gas engineers point of view

[trevorbayliss]

I have seen inside quite a few combi's over the years. When ever i have an issue I always work alongside my engineer to try learn what the issue is. So I see how he changes the secondary heat exchangers , for example.

I've removed my own secondary HE and cleaned it out. I have the vaillant eco plus 837 and its doing fine at coming up to 16 y/o. On all the other boilers ive seen, removing the Sec HE would be a bit hard for me as you have to remove other bits.

Which boilers are good to work on ? I'm assuming the slightly bigger cased boilers are the ones to go for if space is not an issue.

Ideal Logic everytime

Baxi 105 e/he
Baxi duotec
Baxi 600 series
all an absolute piece of cake to work on with plenty of space to get at all the parts

Like the Logic, Vogue, Baxi 105, Vokera Flowmatic and excel
Intergas too

I’ve worked on a few, probably easiest is Vaillant ecotec pro and ecomax, the new Sustain isn’t. I also like the Potterton suprima HE which could be a rebadged one mentioned above.
