High-Efficiency MagnaTherm® FT Firetube Boiler

High-Efficiency MagnaTherm® FT Firetube Boiler


Modern heating appliances are expected to respond to a dynamic range of operational demands, all the while maintaining optimal performance with ultra-high efficiencies.

The MagnaTherm FT meets the challenge by deploying a powerful array of solution based design considerations and proprietary control algorithms. This powerful array of capabilities results in a boiler that performs optimally under all manner of variable conditions and offers exceptional efficiency and reliability.

All in, the MagnaTherm FT is the ideal commercial boiler for use in full-flow variable primary systems or can be deployed to maximize primary-secondary installations via the Laars proprietary Vari-Prime® Delta-T control.
