Yes, the V100 is the watered down version for the UK market. The V200
and V300 are more rugged and have better/more options available.

Hmm - I'm intrigued by the "more rugged" bit.

I was looking at the 100 as it's a) tiny; b) simple - I only need heat on an
open vented system into a heatbank. I doubt it's even going to modulate.

Weather compensation is likely to be moot as that could be better
implemented at the heatbank (ie don't fully charge the whole store in
summer.

Or does weather compensation allow the boiler to run more efficiently at
lower outputs in modulating mode?

The 100 has a stainless steel heat exchanger (I presume many decent boilers
do) - so are there any weak points left?

Oooh I don't know much about heat stores.

Don't get me wrong the Vitodens 100-w is a very nice simple boiler.

That sounds like my sort of boiler:-)

How do they organise by-pass? Or is it not required?

My under floor system is split into 3 separate circuits each having a
local thermostat. There are no radiators at present and no towel rail.

At some future date, I may decide to feed an additional radiator load in
an adjoining room.
