Why Should You Buy Viessmann Boilers?

Equipped with a Viessmann stainless steel heat exchanger for lasting performance and reliability, plus a fully modulating MatriX Plus cylinder gas burner, the Vitodens 100-W wall-mounted gas condensing boiler is the perfect combination of value, quality and Viessmann technology. 


Its compact design, zero clearance to combustibles and extremely quiet operation make the Vitodens 100-W an ideal choice for even the smallest spaces. Plus, with a limited residential lifetime warranty, you can be sure your investment will deliver long-lasting value.

Benefits of a Viessmann Boiler :

Outstanding Versatility

  • The Vitodens 100-W offers the right solution for every demand, including space heating or all-in-one combi options; multiple venting options and boiler software that adjusts automatically for vent length with no added coding; and flexible fuel options, with the ability to switch from natural gas to propane at the push of a button, no conversion kit required.

  • Installation, service and maintenance are designed to be fast and easy with all pipe connections located at the bottom, and serviceable components easily accessible from the front. The adjustable user interface control panel can be moved easily from bottom to top to accommodate different height installations.

Domestic Hot Water To Fit Your Family‘s Needs

  • The new Vitodens 100 is available as a B1KE model combi, offering an outstanding continuous draw rate of up to 4.7 GPM † plus added cost savings with the energy-saving on-demand design, or as a B1HE model non-combi boiler.

  • For more hot water on demand, the B1HE (non-combi) makes an excellent pairing with Vitocell DHW tanks. With an integrated indirect circulator, this combination delivers highly efficient, dependable hot water and space heating for families. A DHW recirculation pump can also be used with a range of scheduling options that match your lifestyle (with regular use, B1HE models).

Save, Learn and Have Peace of Mind From Anywhere

  • The Vitodens 100-W offers an integrated WiFi interface, which allows the system to connect directly to the internet allowing for seamless integration with the ViCare App for smartphone or tablet. Once ViCare is connected, homeowners can remotely connect to their boiler and utilize on-demand DHW recirculation, DHW scheduling and temperature control, and visualize fuel usage and cost-savings.

  • With ViCare, homeowners can connect directly to their preferred contractor for scheduled maintenance, preventative service and emergency messages, maximizing reliability and peace of mind that their home‘s heating is up and running from anywhere.
