Replaced an old Potterton boiler with a Vitodens 100-W Combi 5 years ago, best thing I've ever done, and its now payed for itself.
It's been running like a dream, halved my gas bill and electricity bill dropped by about 30% with the high efficiency pump.
A lot of these reviews on here reflect the quality of installation, and not the boiler manufacturer, so always use a Viessmann Trained Installer, that's my little piece of advice.
