I would go for the Vaillant ecoTec. Why do you want to replace your current one?

ur lucky to get 16 yrs ...but having said that worcs were good then ...NOT now ...300 vans on road fixing etc and the waiting time is ....3 weeks for non radical faults...its always a tricky area best boiler
but on a manufacturer basis ...for standard stuff ..Vaillant ..its the Audi of boilers ...I run a Honda Tourer Earth Dream ...
No doubt u will get plenty of really good advice on UKPF later
we are totally independant and tell,it

Vaillant..... overpriced tat.

They use to be good

Heat exchanger blocks at the mere sight of magnetite.... so does the pressure sensor.

In you own personal opinion of course.

Then flush, inhibit and install a MagnaClean

My 2 pence;

Vaillant or Worcester Bosch for me, been fitting them since 2008 and see no reason to change. Reliability has been excellent, shame really as you get less repeat work haha.

Thanks, I didn’t think of that. What would I do without people like you?

Continue to accuse every Vaillant boiler of blocking with magnetite easily which is a bull**** comment?
I'm not sure, just a guess

Okay, thanks for that. I haven’t learnt anything after all this time.

Longest warranty for the cheapest price.

Also, 2 showers on a combi?

 

[jck]

I also have a WB combi CDI 35 (greenstar version) that is now 14 years old, eventually the aluminium heat exchange will fail on the condensation side, it is still OK now but when it will does eventually die , my current list for replacement consideration is a) Atag Economiser 39 b) Intergas Xtreme 36 c) Baxi 636 d) Ideal Vogue C40 (but plastics questionable) e) WB Classic CDI 42 (simplest change, but plastics issues and lack of opentherm). My house uses Evohome for zone control of each room (really like this system) , I have very soft water with excellent supply flow (> 20l/min ) and pressure, and I want to use Opentherm on next boiler. The Atag is probably my current favourite on the list due to excellent DHW flow, good opentherm implementation, excellent efficiency, Stainless steel HX, lack of internal plastic. But I don't like the interface on the Atag boiler (would much prefer to see one like the Vogue), or the location of the expansion vessel, and I would also like to have the central heating turn down of the Intergas (my number 2 choice , behind Atag because of flow) .

 

[king of pipes]

I have a atag economiser in my own home nice boiler well put together but has its faults not the quietest of boilers the solenoid on the gas valve clunks really quite loud it's more like a small commercial boiler , the one control dont even go there dumped mine got the nest now way superior , weather comp didn't work for us simply not warm enough, vogue is a nice boiler but plastic casing and internal components let it down its interface is great though , baxi 636 hmmmm jurys out on that one , intergas extreme look great but untested fitted a few other models and all performed exceptionally well choose a p5 installer 10 warranty worth considering , wb classic the grandad of the bunch serviced one I fitted 4 years ago today still like new fully stripped it other than I bit of aluminium oxide in heat ex still years in it , my next boiler intergas without a doubt.

[Harvest Fields]

I fitted the economiser for a customer, had massive issues with the one controller. Ended up putting in a Hive FOC

 

[DGT plumbing]

They all have there faults some just have more faults than others. Every engineer will have a story about how crap that boiler is whatever you buy after you've bought it.

 

[Jerry]

And still no comments on 2 showers from a combi?

If the customer insisted, I would fit an Ideal Vogue Max Combi with a 12-year guarantee.
However, I am a real fan of the twin pipes in the heat exchanger on the Intergas. Half the components and you can have hot water if the pump fails. Also works on a gravity fed system too.
