New CombiPLUS Kit Brings On-demand DHW Capability to Vitodens 100

Equipped with expanded control logic, the popular Vitodens 100 condensing space heating boiler can now deliver on-demand domestic hot water (DHW) with the new CombiPLUS Kit. This compact, economical solution greatly expands the range of possible applications for the Vitodens 100 – a boiler already known for its versatility, efficiency and reliability.

Slightly bigger than a large shoe box (9.8” x 17” x 8.7”), the optional CombiPLUS Kit can be mounted underneath or beside the boiler with minimal piping and electrical connections, as part of a new boiler installation or as a later addition to a compatible Vitodens 100.

Generating up to 3.6 GPM of reliable on-demand DHW, the CombiPLUS Kit eliminates the need for a DHW storage tank in many lower-load applications such as apartments, condos, cottages, single-family homes or installs where space is at a premium. The compact, virtually silent unit integrates a stainless steel plate-type heat exchanger, built-in pressure bypass, three-speed DHW/space heating pump and three-way diverting valve. Built-in temperature and flow sensors ensure consistent supply, and DHW heating is managed through the boiler’s on-board control.

The CombiPLUS Kit has received Low Lead Content certification by CSA International when installed in combination with the Vitodens 100. The certification indicates compliance with the stringent requirements of the American National Standard NSF/ANSI 372, California Health and Safety Code 116875 and similar standards in Vermont and Maryland.

CombiPLUS Kits and new CombiPLUS-compatible Vitodens 100 boilers are now available through Viessmann Wholesale Partners across the U.S. and Canada. Visit or for more information.
