Offering a 5:1 turndown, the MagnaTherm boiler or volume water heater with Advanced VARI-PRIME™ Boiler Pump Control seamlessly matches boiler firing rate to pump flow, reducing boiler pumping costs. The units are available as a 95 percent thermal efficiency modulating-condensing boiler or volume water heater in 2, 3, and 4 million-Btuh sizes. The units have a small footprint, slim vertical design with removable top section, stainless steel heat exchanger, and multiple voltage options to easily match building service. They feature a large, easy-to-navigate color touchscreen display, which aids in quick setup and diagnostics. Up to eight MagnaTherms can be controlled in a cascading boiler bank. The systems have a unique, sealed condensate trap that does not need to be primed at startup, can accommodate up to 100 feet of vent, and meets the most stringent NOx emission requirements, the company said.
