The newer Viessmann Vitodens 100-w is said to be a great improvement
compared to the earlier Vitodens 100.

That's interesting.

However I would spend a little extra and get the Vitodens 200.

Any particular reason?

Yes. Why?


Curiousity...

I had it on my plans to install a heat only 100 (now 100-w).

Just wondered if I'm missing something with the 200. I can't see it on the
face of it though.

Cheers
