viessmann 100 or viessmann 200

[notalterna]

Hi all,

We're in the process of replacing things in the house and the back boiler has to go.

We've had 4 quotes and am planning to go with one but he installs viessmann. I've read plenty of threads on here and it seems to be highly regarded so think we'll be ok.

The main question is if there is a difference between viessmann 100 or 200? we're being quoted for viessmann 100 30kW for a 3-bed semi with 1 bathroom.

I've read the brochure and to an untrained eye they are almost identical. I'm guessing there wouldn't be much point making and marketing 2 such similar models so there must be a fundamental difference going on here?

The 200 is the better boiler.

dangermouse46 - would you like to explain why ?

The 100 is the cheaper version although personally I'm not a big fan of viessman.

Different casing, different electronics.

100 series is made for UK only, 200 series sold all around the World.

Draw your own conclusions.

Normally you would ask your Viessmann installer specialist for the differences, he should know.

Do these comments refer to the older 100, or to the current 100w (or both) ?
One reason I would consider the 100w is that at 340mm it is the narrowest boiler I'm aware of and I could fit it without having to move (or reduce) a kitchen cabinet.

This is the only country in europe where we make boiler to fit into cupboards. Everyone else makes them to work and be maintainence friendly

German customer: I want the best there is that will be reliable and last me.

English customer : I want something cheap that fits in that cupboard over there

To be fair, I didn't say anything about fitting the boiler into a cupboard, not that it matters much. The present boiler is in a 360mm space between a cupboard and a wall.

my comments weren't aimed directly at you, just generally speaking, don't take offence!

I am a accredited viessmann installer and can only urge you to go for the 200. Had another customer without hot water and heating this weekend after the spark gen on a 100 failed after 18 months.
Common fault.

Thanks everyone, will ask the viessman man about it then. I didn't want to start the process of getting the prices and then finding out he had quoted the best one for me

when I looked, there was not much difference in price between the 100 and the 200 anyway, you will probably not notice it on the complete job, and the 200 does seem to be better. It is a bit bigger but still a reasonable size.

I actually have a 100 compact, which is the non-combi open-vented one, and has far fewer internal parts to go wrong, and is even smaller.

I happen not to like combis.

From what I hear the early 100 combis had a poor component in them, and were quite unreliable, but there is a revised one out now. Time will tell.

If yours is an approved Viessmann installer, and does the job properly, and issues the right paperwork, you will get an excellent long guarantee.

Be sure to find out how many of the exact same model he has previously installed. Mine had never done the same one before (and it showed)

I am a householder not a pro.

the 200w is the better boiler. its built to last a long time, not that the 100 isn't. its just that there are millions of the 200's around the world and faults are not rare on them.
