Product Description

The Viessmann Vitodens 100-W Compact 35 is a condensing regular gas boiler with an output rating of 35 kW, making it the most powerful model in the range.

How efficient is the Vitodens 100-W Compact?

A 94% efficiency rating and ErP A-rating for heat show that this is a very efficient boiler that could help to lower your heating bills.

Is the output rating suitable for my home?

A 35 kW output rating means that this boiler is best suited to larger properties with up to 20 radiators.

Are other options available in the Vitodens 100-W range?

This is the most powerful regular boiler in the range so if you're looking for a lower output then 13 kW, 16 kW, 19 kW and 26 kW models are also available.

Is a regular boiler suitable for my home?

Unlike combi boilers, which heat water directly from the mains, a regular boiler is fed water from a tank in the loft and stores on hot water in a cylinder. While this does mean that they can meet high demands for hot water, they do take up a lot of space.

If you don't already have a regular boiler installed in your home, then a system boiler (which also needs a cylinder but takes water from the mains) would be a more appropriate option.

How long is the warranty period?

As standard, Vitodens 100-W regular boilers come with a 5 year warranty but this can be extended to 10 years if installed by a Viessmann Trained Installer.

What are the key features of the Vitodens 100-W Compact?

This boiler comes recommended by the Energy Savings Trust thanks to being so efficient which comes as a result of a number of features, including an inox Radial heat exchanger. While this is a 94% efficiency boiler, it is able to deliver efficiencies up to 97%.

How big is the Vitodens 100-W Compact?

As the name suggests, this is a compact boiler with dimensions of 600 x 375 x 340mm (HxWxD) and has been designed for wall-mounted installation.
