The Master MH-220T-SDR is a 220,000 BTU forced-air heater that runs on K-1 kerosene, #1 diesel, Jet A or #1 fuel oil. It heats up to about 5,500 sq ft, so it suits large job sites, warehouses and unheated workshops rather than a garage corner. SilentDrive is Master's quieter forced-air design, and a built-in thermostat lets you set a target temperature instead of running flat out. Against smaller torpedo heaters it trades portability for output; against propane cannons it avoids tank swaps but needs a fuel supply and venting.
