By Canadian Consulting Engineer
The new MagnaTherm from Laars is a 95% thermal efficiency modulating-condensing boiler or volume water heater available in 2, 3 and 4 million BTU/Hr sizes. MagnaTherm offers a 5:1 turndown, small footprint, slim vertical design with removable top section, a stainless steel heat exchanger and multiple voltage options to easily match building service. Designed and made in theUSAby Laars, the MagnaTherm meets all ASME requirements and is AHRI certified.
The boiler features an advancedVARI-PRIME pump control that seamlessly matches boiler firing rate to pump flow, reducing boiler pumping costs by up to 70 percent. No other boiler offers on-board control functionality that balances combustion, air flow and water flow to optimize boiler efficiency.
A large, easy-to-navigate color touch screen display results in quick setup and diagnostics. Up to 8 MagnaTherms can be controlled in a cascading boiler bank.
The system has 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.
