On High, it consumes 0.319 gallons of fuel an hour, while only consuming 0.25 gallon an hour on the High-Medium setting. On the Low-Medium setting, it consumes 0.16 gallons of fuel an hour, while the Low setting provides minimal consumption at only 0.12 gallons per hour.
The Monitor 441 promises 93 percent efficiency in its owner's manual. However, this doesn't factor the loss of heat from condensation, which places the true net efficiency of the 441 at 87 percent. The amount of heat generated depends on the setting the 441 is on. On the High setting, the 441 has a rating of 43,000 BTU an hour, for an overall output of 40,000 BTU an hour.
