Despite being very capable, it’s small and compact because Viessmann knows that a boiler shouldn’t take up any more room than it needs to.

It’s wall-mounted so you could fit in your pantry and because it’s small enough, it could go into a kitchen cupboard as well.

You can also access all your presets so if different family members are getting up at different times, everyone can have hot water for their shower or bath.

Wireless remote control is also available for this type of boiler.

The exact measurements are 700 in height, 400mm in width, and 350 in-depth. As you can see, it’s a medium-sized boiler with a truly impressive performance. Viessmann Vitodens 100 w Boiler Review Compare Boiler Quotes
