Product Description

The Viessmann Vitodens 100-W B1KC 35 is a condensing gas-fired combi boiler and the most powerful unit in the range, with an output of 35 kW.

How efficient is the Vitodens 100-W B1KC?

Viessmann are well known for manufacturing highly efficient boilers and this model is no different. Thanks to an efficiency of 94%, making this an ErP A-rated boiler, installing this boiler could help to lower your heating bills.

Is the output rating suitable for my home?

This Vitodens 100-W boilers has a 35 kW output for central heating and domestic hot water, making it suitable for installation in properties with around 15 radiators and 2 bathrooms.

Are any other outputs available in the range?

A boiler that's too powerful for the demands of your home will see your heating bills. So, if this 35 kW model is too powerful then Vitodens 100-W B1KC combi boilers are also available in outputs of 26 kW and 30 kW.

Is a combi boiler suitable for my home?

Combi boilers are single cost-effective heating systems that don't need to be installed alongside any tanks or cylinders. This means installing a combi boiler will save space around your home. However, this limits the amount of hot water they can deliver so if your property has 2 or more bathrooms then you may want to consider a system boiler.

How long is the warranty period?

Available with a 5 year warranty as standard, this can be extended to 10 years if installed by a Viessmann Trained Installer.

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

To make this boiler so reliable and efficient, it features a backlit LCD touchscreen display, a modulationg ratio of 1:6, and stainless steel heat exchanger.

How big is the Vitodens 100-W Compact?

This is a compact boiler that can be installed within a kitchen cupboard thanks to dimensions of 700 x 400 x 350mm (HxWxD).
