Does the Gasland MHA18BN hold a 20-pound propane tank inside?

Yes, the Gasland MHA18BN is designed specifically as a cabinet heater that operates with a 20-pound liquid propane cylinder. The upright cabinet structure encloses the 20-pound fuel tank behind the burner, keeping it contained and off the open floor. This setup eliminates loose cylinders and trailing fuel lines in a crowded workspace. Verify your tank collar width against the cabinet opening dimensions in the product manual before securing your cylinder.

Which heater is easier to transport between job sites?

Mr. Heater portable models are substantially easier to transport. The Mr. Heater Big Buddy weighs between 13.01 and 14.11 pounds with dimensions around 11.02 x 17.72 x 17.13 inches or 16.7 x 11.2 x 12 inches, while smaller options like the 9,000 BTU Portable Buddy weigh only 7.1 pounds. The Gasland MHA18BN measures 17.5 x 15 x 21.7 inches and is built to house a heavy 20-pound tank, making it much better suited for rolling across a single garage floor than lifting into a vehicle.

How do the heat settings compare for heating up to 450 square feet?

Both models are rated to warm spaces up to 450 square feet at their peak output of 18,000 BTU, but Mr. Heater offers more staging flexibility. Mr. Heater Big Buddy models provide three distinct settings at 4,000, 9,000, and 18,000 BTU per hour. The Gasland MHA18BN delivers radiant warmth up to 18,000 BTU for the same 450-square-foot footprint. Having lower BTU stages on the Big Buddy helps you maintain steady comfort on milder 2026 workdays without overheating your shop.

Do either of these propane heaters require electrical power to run?

No, neither heater requires an electrical connection to generate warmth. The Gasland MHA18BN requires no electricity and runs purely on liquid propane, ensuring full heat output during winter storm blackouts. Mr. Heater radiant heaters also burn propane independently of the electrical grid. If you prefer a supplementary electric option for a small workbench rather than running open fuel, plugging in a low-wattage space heater can warm your immediate seating area cleanly.

What built-in safety shut-off features protect your workspace?

Both heaters incorporate low-oxygen sensors and automatic tip-over shut-offs. The Gasland MHA18BN carries CSA certification, using its integrated tip-over switch and low-oxygen system to cut gas flow if bumped or if room oxygen drops below safe levels. Mr. Heater models such as the Little Buddy feature tip-over switches and oxygen depletion sensors, and units like the Big Buddy NF are rated for indoor and outdoor use. Always check that your workshop provides the fresh air intake listed in the manufacturer guidelines.

Which heater works better for mobile shelters and outdoor trips?

Mr. Heater units are better suited for mobile setups due to their compact footprints and lighter weights. Carrying a 13.01-pound Big Buddy is straightforward when packing gear for outdoor projects or remote sheds. The Gasland cabinet design is bulkier and built specifically to keep large tanks organized inside workshops. If you want a dedicated, externally vented heating solution for a van build or enclosed trailer rather than a portable propane unit, a diesel heater for camper installations provides a permanent dry-heat alternative.
