12 Volt 300 Watt 9 3/8 Inch DC Submersible Water Heating Element

Can be used direct with batteries, solar panels, hydroelectric generators, as a wind turbine dump diversion load. You can run high voltage through the element as long as you don’t exceed the rated wattage of the element.

For example, a 600 watt element can handle a 600 watt max solar array output of 150 volts 4 amps and a 300 watt element can handle a max output of 300 watts 200 volt at 1.5 amps. As long as your panel(s) voltage exceeds the element voltage rating but does not exceed the max output wattage, you can safely use the element.

DO NOT USE GRID POWER AS IT WILL IMMEDIATELY DESTROY THE ELEMENT!

Uses:

Livestock water tank deicer (low amp draw means you won’t drain your battery as fast). For keeping dog, cat, chicken, and other domestic animals’ water from freezing.
Standard American water heater element replacement for on or off grid applications
Water preheating
Campers, Motor homes
Emergency hot water
Portable commercial, industrial machines and equipment
Runs off your car battery for portable hot water anywhere
Direct wind and solar applications
CONCRETE MIXING TRUCKS
Use for DIY solar batch water heaters
For heating motor oil, vegetable oil, or most any other oils or liquids
and many, many more uses where heat or diversion loads are needed.

Question: How many watts are required to heat one gallon of water up one degree?
Answer: It requires 2.4705 watts for one hour.

DC water heating elements are much safer than 110 volt

Note: If you have a gas hot water heater you may wish to put an electric unit ahead of it. This way the gas heater is always being fed hot water so it does not turn on as often and for shorter periods of time when it does.
