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.
