Igloo Cooler Based Nitrous Bottle Water Heater – This bottle heater can hold 15 lbs bottles as well as 10 lb bottles. It weighs 22lbs (without bottles) and measures 21″ high, 21″ deep, and 24″ wide. It’s equipped with a Johnson’s Controls mechanical temperature controller, two 1500 watt 120v heater elements (one primary and one backup). Functions great, the controller holds temperature really good, but it is not as easy to set as a digital type. Asking $100, probably don’t want to ship this due to costs, can pickup at my location in LaHarpe, KS or make arrangements to take to one of the MAKO or other shootout races we’ll be at this summer.
