Smallest Installed Footprint

The MVB’s compact design allows for easy installation in the most challenging equip- ment rooms. It’s easy to handle and install, but still user friendly to service. The MVB has the smallest installed footprint of any vertical boiler, only 5.4 square feet. The MVB con- tains all of it’s components to the inside of the cabinet, so there won’t be any fans or valves hanging off the cabinet that need extra clearance. The compact design fits through a 30” door opening making it the perfect choice for those hard to reach retrofit projects.
