Whether RV-ing for the love of it, living in a park unit or camping, many people are using their vehicles throughout the entire year. A common problem is that water holding tanks may freeze up in cold winter weather. As water tanks turn to ice, basic RV necessities such as toilets, showers, and sinks fail to function. The solution is simple. Protect your water tanks in freezing temperatures with the Madison Accessories Tank Blanket. The Tank Blanket is an auxiliary heating device designed to be applied to the exterior of a holding tank in RV’s, Motorhomes, camping trailers, and/or other commercial vehicles. Simply stated, it is an electric heating blanket for your various water tanks. The Tank Blanket is made up of a laminated heating element, a thermostat switch and a rubberized backing material with an outer aluminum layer. The entire inner layer, opposite the aluminum outer layer, is covered in a Pressure Sensitive Adhesive that allows the user to “stick” the heater blanket onto the tank.
