Overview
Not a plug-in electric unit, the Mr. Heater Big Buddy burns propane to give radiant and forced air warmth without the need for batteries. A floor-standing tower with a carry handle, it moves between living rooms, bedrooms, garages and job sites, and the listing ships two heaters.
Two heaters in one listing means two rooms, or a garage and a workshop, can be warmed at once, each on its own heat setting. Noiseless running suits bedrooms. Against that, propane indoors calls for proper ventilation, and the listed dimensions disagree on depth.
Who it's for
Garages, workshops and living rooms without central heat are the situation the pair covers. Someone who needs only one heater, or cannot ventilate the space, should look elsewhere.
Pros and cons
- Two heaters in one listing
- Radiant plus forced air output
- Runs on propane, no batteries needed
- Carry handle for moving between rooms
- Sold as a pair only
- Indoor use needs proper ventilation
- Depth differs between specs and description
- Fuel cylinder and hose not listed
Performance notes
Room warmth depends on the heat setting chosen and on how the forced air spreads radiant heat across the space. Larger or drafty rooms thin out the output, and the ventilation the listing calls for also lets some warm air escape.
