Vaillant, Worcester-Bosch, Viessmann boilers

WB only have the cheaper alloy heat exchanger.

Are Ali-alloy exchangers still an issue, or has it been resolved?

Would the choice of boiler be made more easy if it were restricted to only those with SS mainXs?

That hasn't prevented my WB boiler from running perfectly fine for the past 13+ years.

40 years repairing boilers worked for four manufactures still spend most days repairing worcesters would not put one in my house or any of my customers, and the vast majority engineers that I know that have to repair them think the same.
Plastic manifolds that leak very badly designed cheap materials aluminum and plastic.

Best advice I can give customers is Baxi or Main Stainless steel copper and brass all parts  can be changed in under 30 minutes much better design and also cheaper.

Worcester Bosch have a wonderful marketing department.

I can't say I've had a brilliant experience with Baxi but I think I had a dodgy boiler from the outset.

My 16-year old GlowWorm is still running perfectly.

It's only required a new mainX, both hydroblocks, pump, PCB, 4 P2P exchangers and a filling tap. Oh, and an auto by-pass. And two flow switches.

The casing is immaculate.

Sounds like Triggers brush

Baxi and Intergas are my preferred choices,  Intergas most won't have heard about but they have a lot less parts to worry about than any British boilers and are one of the most reliable brands in Europe.

Baxi because my old 105e lasted 16 years with just one new PCB in all that time and swapping it for a Duo-tec was as easy as lifting the old one off the frame and fitting the new one straight onto the old frame.

WB have lost a lot of respect in the industry ever since they became Bosch, the old Worcester boilers deserved their reputation, they were bullet proof. The new Bosch ones are no better than any others now, not bad but not as good as some, they are still the easiest boiler to sell though because it's a household name, and people listen to their cousins daughter who tell them they are the best, it's hearsay but still sells the boilers  and will continue to do so.

To be fair they've been Worcester Bosch for almost 30 years now and combi boilers weren't that much of thing prior to that.

I’ve posted before on this issue, but our Vaillant ecotec pro28 is now nearly 8 years old, it had a few problems in the first 3 years, all sorted under guarantee.

But........it’s performance is awful.  Take today, it’s cold, it’s 3° outside.  The boiler came on at 4pm, just over 2 hours ago and yet it’s just bumbling along at 54° ish on the display, when it’s max is set at 73°.  The radiators are hot-ish, certainly nowhere near boiling.  I’m calling for 22°, so why doesn’t it crank up into the upper 60’s at least and get the radiators boiling hot?  I’ve basically had enough of it and it’s replacement next year won’t be another Vaillant.  Looking at the Ideal Logic C30 as a possible replacement.
