Propane or electric patio heater — which should I buy?

Propane models (typically 40,000–55,000 BTU) push more raw heat and work anywhere without an outlet, making them better for open or large patios; verified-purchase volume in this category is overwhelmingly behind propane towers. Electric infrared units are quieter, fuel-free, and better for covered porches, balconies, or anywhere fumes and refilling tanks are a hassle, but they generally heat a smaller, more directional zone and need a nearby outlet or hardwiring.
