Don't let the temperature stop you from entertaining outdoors: This patio heater has what it takes to keep everyone happy. Its 47,000 BTU output warms up a range of about 10', and is powered by a 20 lb. propane tank (not included) that fits right in the base of the heater. Plus, it features a wheeled design that makes it easy to move exactly where you need it. There's also a safety shut-off in the event that it tips over.
