Gusty winds can make you anxious about your patio heater getting knocked over. This weighted base lets you focus on your relaxation while you are outside enjoying your Ellipse or Real Flame Heater. Just place this affordable accessory inside the base, below the tank (for liquid propane models) to add 1 lb to the heater's weight. This provides additional support which makes your unit more stable, especially on windy days. Carry on with whatever you are doing without worrying about the wind.
