Many variations can be done at Reimers to give customers advantages in floor space or mounting. Heavy steel framing is made in-house to fit the design. Any boiler or hot water system may be used in the framed package. When closed blowdown tanks are used the need to vent outside is eliminated. Condensate return options are available for any model to recover energy costs. Have Reimers assemble and mount the whole system, it is a cost saver for you not to do it at the site location. Just move the assembly in to place and connect a power source. When an electric boiler system is needed Reimers has a size that is ASME and UL approved.
