Mr. Heater Portable Heaters: Trusted Warmth Anywhere You Need It

Mr. Heater has been delivering safe and reliable heat since 1957, and nowhere is that legacy more evident than in their lineup of portable heaters. Whether you're warming an ice fishing shanty, a job site trailer, a hunting blind, or a campsite, Mr. Heater has built a reputation as North America's most trusted name in portable propane heat.

The Buddy Series: An American Icon

At the heart of Mr. Heater's portable heater lineup is the iconic Buddy series — a family of radiant propane heaters that has become synonymous with portable warmth. The lineup spans multiple sizes and output levels, from the compact Little Buddy designed for personal use in small spaces, to the versatile Portable Buddy, to the powerful Big Buddy for large enclosed areas. The Tough Buddy extends this family further with a rugged design built for demanding outdoor and worksite environments.

What sets the Buddy series apart is its patented radiant heating technology. The Portable Buddy, for example, delivers 4,000 to 9,000 BTU of output and can heat up to 225 square feet — connecting directly to a standard 1 lb. propane cylinder, or to a larger 20 lb. cylinder via an optional hose and filter. Ignition is handled by a built-in Piezo sparking mechanism, meaning no matches or external igniter required.

Safety Engineering You Can Rely On

One of the most compelling reasons to choose a Mr. Heater portable heater is the brand's commitment to safety innovation. The Buddy series features a patented Oxygen Depletion Sensor (ODS) that continuously monitors air quality and automatically shuts the unit off before CO₂ reaches unsafe levels. Combined with an accidental tip-over safety shut-off, these heaters are among the few portable propane models certified safe for indoor use in enclosed spaces with proper ventilation — a distinction that makes them ideal for tents, RVs, garages, and emergency shelters.

• Oxygen Depletion Sensor (ODS): Automatically shuts off the heater if oxygen levels drop
• Tip-over safety shut-off: Kills the flame instantly if the unit is knocked over
• No electricity required: Fully self-contained, perfect for off-grid or emergency use
• CSA certified: Indoor-safe when used as directed with proper ventilation
• Swivel regulator: Adapts from a disposable 1 lb. cylinder to a larger remote gas supply

Versatility Across Every Application

Mr. Heater's portable heater range extends beyond the Buddy family. The lineup also includes tank-top heaters, forced air propane heaters, and cabinet-style heaters that scale output to the demands of larger open spaces such as construction sites, barns, patios, and warehouses. With BTU outputs ranging from a few thousand up to 30,000 BTU and beyond, there's a Mr. Heater solution suited for intimate personal spaces and expansive work environments alike.

With decades of proven performance in the field — from ice fishing shanties to emergency relief efforts — Mr. Heater portable heaters represent a rare combination of thoughtful engineering, practical portability, and safety-first design.
