M255 PE - Water Capacity: 90 gal. - Weight: 1,297 lbs
Maxim M255 PE thermal output rating: 182,504 Btu/hr (53.5 kW) - maximum
Thermal Output Rating*: Manufacturer's Rated Heat Output Capacity: 190,000 Btu/hr
Annual Efficiency Rating*: 96.2% (lower heating value), 89.2% (higher heating value)
*Performance is a product of the combustion rate, combustion efficiency and heat exchange efficiency with a single fuel load without refueling.
Results vary based on wood species, wood quality, wood quantity and moisture content. Efficiencies are determined under the same test conditions
using higher heating value, lower heating value and annual fuel utilization efficiency (AFUE).
