Laars Expands MAGNATHERM Boiler Line

MagnaTherm Photo 2Laars has expanded its MagnaTherm boiler/volume water heater line, now to include 1.6, 2, 2.5, 3, 3.5 and 4 million Btu/hr sizes.

The modulating-condensing systems from Laars have 95 percent thermal efficiency and a 5:1 turndown. The systems also have a 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 the USA, the MagnaTherm meets all ASME requirements and is AHRI certified.

The boiler features an advanced VARI-PRIME pump control that seamlessly matches boiler firing rate to pump flow, reducing boiler pumping costs by up to 70 percent. This unique on-board control functionality 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.
