Worcester 25si or Viessmann Vitodens 100 26kw?

[sunflowers8]

Hi

I've decided to install one of the above combi boilers and wondered if anybody has any thoughts on either and advise which, in your opinion, is the better option, please?

Many thanks.

Hi. When you say 'install' do you mean hang on the wall yourself or have a GSR install for you?

My preference would be the V but it really depends on your requirements.

 

[IDCHAPPY]

Go for a Viessmann, not that I've worked on them but they get good reviews

 

[Ermintrude]

Agree. Owt but worster poop

 

[Geyser]

I'm off worcester gas combis at the moment. To many leaking heat exchangers, electrical faults and cut hands. No experience on viessman but I hear good things. I'm giving atag a go where space allows!

Haha I wish I could install it myself but sadly not.

I have a small 3 bedroomed, 1 bathroom house.

Make sure system is clean and have central heating filter installed !

 

[Ermintrude]

Stan u fitted many wb filters? Never fit wb anymore but filter and conny warmer looked ok

 

[SafeGasInstall]

no , never fitted even one tbh ! I have installed many magnaclean 2 and the new one ! Just the look of the wb one is making me not to even think about installing it ! I did quote on a job to install one as boiler was going to be fitted in utility room , but guess what .....did not get the job

 

[townfanjon]

Viessmann all the way !!!!!!!!

Haha sadly I'm not that skilled!

I live in a three bedroom semi with one bathroom.

Have had quotes of £1,800 for them both which includes a clean, filter and digital stat.

I note the the comments made about WB and wonder why all the plumbers who've been round and have all rated them top?

 

[Howsie]

Probably because they are making more money off them.

 

[SafeGasInstall]

Simply because there customer service is excellent and boilers are really well build !

I dont say Viessmaann are bad just personal choice always is WB !

 

[SafeGasInstall]

Also make sure your central heating gets power flushed !!!

Viessman or ideal logic I could not bring myself to soil my hands with a plastic fantastic wb yuk.:smug:

 

[Roger Welton]

Anything but WB

 

[woodsy]

Agree , definitely not wb - fitted my first Veissmann before Xmas, the 100w system boiler and was very impressed with it.

 

[Roger Welton]

Only thing that puts me off the viesmann 100 is the rubber hoses on primary hex, they seem to attract sludge to them like a magnet.

People slating Worcester lol, but the viessman has rubber hoses lol?!! We all know what happened to vaillants leaky rubber hoses...

 

[Jimbob]

I've been fitting viessmann 100w's for a few years, and yes the rubber hose would be my only real criticism. But I've only had one go around a year after installation. But 7 year warranty which is extendable to 10 isn't bad!

 

[Jimbob]

And the best new thing is combined condense and discharge... So less work

 

[Roger Welton]

I do like the condense/ prv on the WB1C and wish more manufacturers would do this.

Not sure this complies with installation standards. Thought PRV discharge had to be in metal to withstand pressurised steam and condensate had to be in plastic due to the acidic nature of condensate.

Hiya sunflowers8 your question is often asked and all the experienced fitters below will give you their honest opinion based on their wide practical experience.

However as you are not qualified to fit my advice is thus -
1. Dont tell the c/h outfit you choose what boiler to fit its up to them !
2. get a few quotes from local fitters - some on here maybe
3. Make sure your fitter is registered and maybe affiliated to the manufacturer
of the boiler he recommends then you will get extended cover

If you qualify you may get a one free-

but as you asked I dont do models of boilers but tend to go for a brand -
Vaillant all day long...no comebacks from my point of view as an installer

Despite the cynicism of the forum members sunflower, Worcester Bosch continue to be market leader for the nth successive year, with a market share significantly greater than their nearest rivals.

You have picked little and large here - Veissman's turnover in the UK is vanishingly small compared to Worcester. Inevitably, engineers will come across many more failed worcesters than failed viessmans - simply because the installed base of Worcesters is 100 times larger.

 

[ggman]

They're both made of expensive German plastic!!!!. Viessman 100 has as well very long rubber hoses.
Go for the Viessman 200, expensive but better built.

 

[Ray Stafford]

They're both made of expensive German engineered composite polymer material

There ya go ggman - I fixed your typo for you.

 

[sunflowers8]

Thanks again so much for all your comments. Invaluable as always.

I might be fitting a freebie in a close relatives on the Eco. To be honest am in two minds really, he was going to buy a Valliant but he qualifys for this now
