The product is aimed at RV, camper and marine owners who need a simple, low-wattage solution to prevent fresh, grey or black tanks from freezing; the single biggest reason to buy is the built-in thermostat that automatically powers the pad between 41F and 59F so it runs only when needed. The pair of pads and long 10 ft cord make them convenient for many tank layouts, and the 45W output keeps drain on household or shore power modest while preserving access to stored water.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermostat control:\u003c\/strong\u003e Built-in thermostat turns the pad on at 41F and off at 59F so it prevents freezing without continuous power use.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh efficiency heating:\u003c\/strong\u003e Closely arranged heating wire and 6mm thermal insulation help retain heat and focus warming on the tank surface.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature protection:\u003c\/strong\u003e An internal protector cuts power above 158F to guard against overheating and the protective foam uses flame-retardant material.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide application:\u003c\/strong\u003e The 12 in x 18 in size fits many fresh, grey and black water tanks in campers, trailers, motorhomes and boats.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReady to install:\u003c\/strong\u003e The pads include a 10 ft power cord and can be attached in a few steps for most tank locations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnergy conscious output:\u003c\/strong\u003e 45W per pad provides modest heating that is compatible with 120V shore power without excessive draw.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe Kohree heating pad is best for recreational vehicle owners, boat owners and anyone winterizing tanks up to about 50 gallons who wants a low-maintenance, thermostat-controlled pad that powers only when temperatures fall.
