Description
The Mr. Heater MH18B (Big Buddy) uses a dual system combining radiant heat with a built-in fan to create convection for more effective air circulation in enclosed spaces like cabins or garages, making it both a radiant and convective heater for better overall heating. It heats with infrared ceramic plates (radiant) and uses a battery-powered fan (convection) to push warm air around.
Factory-reconditioned and tested.
Stop worrying about the winter chill and start enjoying your favorite spaces again. Whether you are dealing with a drafty workshop, a freezing hunting cabin, or the uncertainty of a power outage, this portable heater is designed to solve your coldest problems with ease.
Total Room Warmth, Not Just Hot Spots
One of the biggest frustrations with portable heaters is that the heat often stays trapped in one corner. Fortunately, this model features a built-in fan powered by a 6v AC adapter. This system ensures that warm air is pushed throughout the entire room, eliminating cold pockets and creating a consistent, cozy environment. Furthermore, you can customize your comfort with three precision settings:
-
Low (10.8 Hours): Perfect for maintaining a steady, comfortable temperature all day.
-
Medium (4.8 Hours): Ideal for quickly warming up a workspace on a brisk morning.
-
High (2.4 Hours): A powerful blast of heat to combat the harshest freezing temperatures.
