Looking for Mr. Heater F274805 Big Buddy propane alternatives? You might want more heat or a different form factor. The original Big Buddy is a compact 18,000 BTU unit that fits small spaces.

These alternatives were chosen because their specs overlap with the original’s propane fuel type and safety focus, while offering higher BTU outputs or different sizes. This list compares 6 similar picks to help you find the right fit for your specific heating needs.

Comparing Mr. Heater Big Buddy Alternatives
Amazon Basics 46,000 BTU Propane Patio Heater
The Amazon Basics unit delivers 46,000 BTUs, far exceeding the Big Buddy’s 18,000 BTU output. It stands 91.3 inches tall, making it a freestanding patio heater rather than a portable box. It weighs 40 pounds and includes wheels for mobility. You gain significant heat for larger commercial patios but lose indoor safety certification.

Choose this if you need raw power for outdoor decks and do not require compact portability or indoor compatibility.
Mars Explo 50,000 BTU Propane Patio Heater

It includes wheels for movement but weighs no specific amount in the data. This model is designed for large outdoor gatherings on gardens or commercial decks. You sacrifice the Big Buddy’s compact size and indoor safety features for massive heat output. The Big Buddy fits in a garage; this unit requires a large patio. Pick this if you prioritize heating power for open spaces over safety sensors for enclosed rooms.
