Well then - look at there non combi range - most of the Pros and cons
are likely to be much the same. But you could easily look at the
Viessmann with weather comp.

:-) I have just fired up a 30kW Viessmann in the cottage. I'm not yet
familiar with the controls. Weather comp yes. Different temps. for hot
water and heating, yes I think. You can certainly switch off the heating
for summer. Clear display.

I have a 30kW condensing boiler and new flue for anyone offering an
appreciative home. 5 years old (2 years work and 3 resting). Potterton
precision.
