Water Overheat and Freeze Thermostats
Use these thermostats with our DC water heating elements if you need to regulate the temperature of the liquid you are heating.
The first option is our 35 degree F freeze thermostat which keeps water and other liquids from freezing. It turns on your element before the liquid freezes at 35 degrees F (closes the circuit) and turns it off (opens the circuit) when the liquid's temperature reaches 55 degrees F. Therefore, your liquid will never freeze but you won't drain your power by heating it over 55 degrees.
- The thermostats remain on until the temperature of the liquid reaches the rated number. For example, the 140 degree thermostat will remain on until the temperature reaches 140 degrees F.
- All of our thermostats can handle 50 amps at 12 volts! No relay needed! (Can handle all voltages from 12 to 220 volts, AC or DC)
- Opens circuit on overheat, effectively cutting power to the heater (normally closed connects).
- Simple in-line wiring system
- Connections are 1/4" spade terminals
- The heat sensor (reverse side) must be firmly mounted on the side of tank with screws or silicone caulking
- Uses a simple and typical "loop" circuit to interrupt power to wiring harness on overheat (Use 10 gauge wire for loop circuit).
- Approximately 1 x 1 x 1 inches in size
Heat ratings are averages (+ or - 3%)

Fahrenheit to Celsius conversions:
- 35 F = 1.66 C
- 55 F = 12.77 C
- 120 F = 48.88 C
- 140 F = 60 C
- 170 F = 76.66 C
