Product Description

The Vitodens 100-W System Boiler offers compact dimensions, low weight, and quiet operation—all of which integrate seamlessly into any living space.

The modulating ratio of these boilers is up to 1:6 over the entire output range. In smaller apartments and well-insulated homes, this high ratio makes these boilers particularly suitable for use. With fewer appliance start-ups, there is less noise and stress placed on the appliance, thus extending its overall life.

How suitable is a regular boiler for my home?

For a complete and comprehensive installation of a regular boiler, there is a need for a lot of pipework. The reason is that the installation needs extended systems such as the feed tanks, extension tank, and a hot water cistern.

That said, if you have adequate space in your home to accommodate the installation of all these extension systems, you are good to go with a regular boiler. Also, if your home currently has an installed, regular boiler, installing another one is suitable for your home. However, if your home lacks any of the above two, you should probably consider installing a system boiler instead.
