The VMP™ is Fulton’s Vertical Multi-Port design convection heating boiler, available for both steam and hot water applications. 

 Inside the VMP, a series of heavy-walled large diameter schedule 80 flue pipes are welded to the top and bottom heads in the pressure vessel. These pipes are surrounded by water. The water-backed design reduces start-up time and creates even heating throughout the boiler. 

 With such a rugged design, the VMP offers exceptional value over the lifetime of the boiler, with fuel to steam efficiencies up to 84%.
