The Trojan 66B Stock Tank Heater offers a thermostatically controlled heating solution that uses LP Gas or Natural Gas instead of electricity in your stock tank. Our 66B offers a powder coated, heavy steel casing and a control & burner assembly that is designed to stay lit and is easily removed for servicing. Adjustable brackets allow the 66B to be mounted to most metal, poly, wood and concrete tanks. The Trojan 66B Stock Tank Heater keeps a 3 to 5 foot radius of drinkable water around the heater at all times. Includes propane hook-up kit.
