DC Water Heating Temperatures
How many watts will it take to heat a given amount of water?
Use the handy chart below that our General Manager David McDaris created to figure how many watts per hour you need to heat water using a DC water heating element. Whether it's a stock tank, water for chickens or other animals, fountain or a converted water heater for your home, this chart will help in sizing your water heating element.
If it's overheating you're worried about, make sure you add a thermostat to your setup. To keep water from freezing, add our freeze-stat.
How many watts does it take to heat a gallon of water?
As a general rule of thumb, it requires 2.47 watts of power to raise the temperature of one gallon of water one degree in one hour.
Formula: 2.47 Watts x 1 Gallon x 1°F in 1 Hour
