How these alternatives compare
DR. Infrared 35-Inch Mounted Electric Patio Heater
The DR. Infrared 35-Inch Mounted Electric Patio Heater replaces propane with standard electricity. At 8 pounds, it is significantly lighter than the 13-pound Big Buddy. Its 35-inch size is much larger than the Big Buddy’s 16.7-inch length, but it mounts to walls or ceilings. This unit lacks portability since it requires a fixed power source. It offers a remote control, which the Big Buddy does not list. Choose this if you want a permanent, cordless-free solution for a covered patio or garage. It is not suitable for open outdoor spaces or areas without electrical outlets.
Hykolity 50,000 BTU Propane Patio Heater
The Hykolity 50,000 BTU Propane Patio Heater delivers nearly triple the heat output of the Big Buddy. At 32.5 pounds, it is heavier and much larger, standing 87.3 inches tall compared to the Big Buddy’s 12-inch height. This unit is designed for medium outdoor spaces requiring intense, focused warmth. It sacrifices the compact, indoor-safe design of the Big Buddy for raw power. You should pick this alternative if you need to heat a larger deck or yard. It is not ideal for small rooms or users who need a lightweight, easily storable heater.
Mars Explo 50,000 BTU Propane Patio Heater
The Mars Explo 50,000 BTU Propane Patio Heater matches the Hykolity in heat output but differs in build. It weighs 48 pounds and measures 32 inches in height, making it a stable, robust option for large patios. This model includes wheels for movement, a feature absent in the Big Buddy. It prioritizes stability and raw power over the portability and indoor safety certifications of the Big Buddy. Select this heater if you need intense heat for commercial decks or large gardens. It is not suitable for small indoor spaces or users seeking a lightweight, compact heating solution.
Jocoevol 18,000 BTU Portable Propane Cabinet Heater
The Jocoevol 18,000 BTU Portable Propane Cabinet Heater matches the Big Buddy’s heat output but differs in form factor. It weighs 18 pounds and stands 23 inches tall, making it taller and heavier than the Big Buddy. This unit is designed for medium spaces needing cordless propane heat. It offers adjustable heat output and robust safety features similar to the Big Buddy. However, it lacks the compact, low-profile design that makes the Big Buddy easy to store. Choose this alternative if you need a taller, standalone propane heater for outdoor use. It is not ideal for users prioritizing minimal footprint or indoor versatility.
Pasapair 1500W Carbon Hanging Patio Heater
The Pasapair 1500W Carbon Hanging Patio Heater uses electricity instead of propane. It weighs only 6.38 pounds, making it much lighter than the Big Buddy. This unit mounts to ceilings, saving floor space entirely. It provides instant heat for covered patios where you are seated. Unlike the Big Buddy, it is not portable and requires a fixed power source. It is best for small, covered gatherings.
