According to TacticalIntelligence.net, common issues with Mr. Heater Big Buddy heaters include blocked regulator and control valves, noisy and weak fans, leaking hoses, and fuel inefficiency. Once destroyed, the heaters are similarly unrepairable.
The regulator and control valve on the Big Buddy Heater can become clogged by residue created owing to the high PSI from the propane tank when used with the 20-pound tank. Rather than simply shutting off the heater, this can be prevented by turning off the tank first and allowing the fuel left in the pipe to burn fully. This obstruction can also be avoided by using a gas line filter. If the user’s instructions are not followed and the valves and regulator become clogged, the heater is permanently destroyed and there are no repair possibilities.
A battery- or AC-powered fan propels heat in the Mr. Heater Big Buddy heater. This fan has a noisy motor, and consumers have complained that it isn’t powerful enough to circulate heat in larger rooms.
Hoses that leak are caused by a chemical reaction between the rubber and the gas, which results in an oily residue. The hose can be changed with one that contains a pressure lowering regulator to eliminate this problem.
The Big Buddy Heater is inefficient since it uses one- or two-pound propane tanks that must be replaced on a regular basis. To minimise carbon monoxide poisoning, the alternative 20-pound tank requires a properly-maintained hose and regulator, as well as the tank being located outdoors.
