Product Description

The Viessmann Vitodens 100-W B1KF is a hydrogen-ready condensing gas combi boiler that's efficient, reliable and quiet. It's an updated version of the previous B1KC model.

How efficient is the Vitodens 100-W combi boiler?

This is one of the most efficient combi boilers available on the market. It has a 94% efficiency rating which makes it an ErP A-rated boiler for heat and water.

Is the output rating suitable for my home?

This combi boiler has a central heating output rating of 25 kW, making it well suited to homes with 10-15 radiators. It also has a domestic hot water output of 31.7 kW so that it can meet the demands of homes with 1-2 bathrooms.

Are any other options available in the range?

Should you need an alternative output for your new combi boiler then the Vitodens 100-W range also includes central heating outputs of 296 kW and 32 kW.

Is a combi boiler suitable for my home?

Combi boilers are a great option for properties with limited space as they're cost-effective units that don't need to be installed alongside any additional tanks or cylinders. As they don't store hot water in a cylinder, they are limited to how much water they can deliver so are best suited to homes with 1-2 bathrooms.

How long is the warranty period?

Featuring a 5 year warranty as standard, this can be extended to 12 years if installed by a Viessmann Trained Installer.

What are the key features of the Vitodens 100-W combi boiler?

The Vitodens 100-W range of boilers are all hydrogen-ready, which means they're ready to continue heating the home should the gas network switch to a hydrogen blend (20% hydrogen and 80% natural gas).

Vitodens 100-W boilers have a user-friendly touchscren digital display, include a stainless steel heat exchanger and a modulation range of 1:6, both of which help to lower your heating and energy bills.

As with most Viessmann boilers this range of boilers is compatible with LPG if you aren't connected to the gas mains.

How big is the Vitodens 100-W combi boiler?

Weighing in at 38kg and measuring 700x400x360mm (HxWxD), you'll be able to hide this boiler within a standard kitchen cupboard.

Note: The Viessmann 100-W B1KF is an updated version of the B1KC which included outputs of 26 kW, 30 kW and 35 kW.
