Donner Power Electric Patio Heater Review

Some models produce up to 38,000 BTUs of heat, which is enough for a medium-sized deck or patio. They are powered by a standard 20lbs propane tank and feature a built-in safety valve.

Most patio heaters are freestanding or wall-mounted, and they stand between 7-8 feet high. They plug into a standard 230-volts electrical outlet.
