The Lava Heat Italia Alto Liquid Propane Gas Patio Heater can be utilized all year-long in the comfort of your outdoor environment. The Alto patio heater generates infrared radiant heat rays which heat objects rather than the surrounding air, keeping you cozy and warm by the pool, spa or on your deck long after the sun goes down. Infrared heat provides efficient, clean burning performance and uses less fuel while providing ultimate comfort. The Alto can be operated for up to 10 hours with a 20 lb. propane tank (LP tank not included). It has solid steel construction, weighted base, integrated table, swing door for easy tank access and a push-button electronic ignition. The built-in Safety-Tilt switch shuts the unit off if it tilts or falls over.
