48 volt 1000 Watt DC submersible Water Heater Element With FREE THERMOSTAT

Increased surface area reduces water heating time! Heat water faster with these curved water heating elements!

Our DC Water heater elements come in a variety of styles and power ratings, Our elements are primarily used for wind turbine and solar panel diversion "dump" loads, to shed excess power for heating water for FREE, Dc Water Heating elements can also be used for stock tank heaters or to heat outdoor pet water and so much more! All uses are powered by low voltage which has its safety advantages over high voltage heaters.For more uses keep reading! Comes with a free thermostat of your choice. See Below!

Application Ideas
* Livestock water tank deicer (low amp draw means you won't drain your battery as fast)
* keeping dog, cat, and other domestic animals water from freezing
* Standard American water heater element replacement
* 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
* and many, many more uses where heat or diversion loads are needed

Element Specifications

  • Low Voltage submersible Water Heater Element
  • Tube diameter is 8mm
  • Tube length is 7 inches (177.8mm)
  • Foldback length is 3.94 inches (100mm)
  • Overall length is 8 5/16 inches
  • Fits standard water heaters with a 1" NPT or your own custom heater tank.

You can use a simple two or three prong standard ac cord to hook up the unit direct to your battery, solar panel, or other low wattage power source or generator. Hook several units together in parallel to increase the wattage. The heater is safer for people and pets because of the low voltage. Low voltage has little effect on the body unlike higher voltage ac units that short out and electrocution can occur.

Choose your Thermostat! Choose between  120, 140, 160, 170,180,190,or 200 degrees Fahrenheit OR our ANTI FREEZE thermostat  which will keep your water between 35 and 55 deg F. DC thermostats are  for 48 volt DC water heater systems .This thermostat is on until the temperature reaches its rated Temperature. ! No relay needed! Opens circuit on overheat, effectively cutting power to the heater (normally closed contacts). DC thermostats are  for 48 volt DC water heater systems.

Thermostat Features:

  • 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). 
  • Heat ratings are averages (+ or - 3%) 
  • Non. Pos. / Neg. polarity

Remember NEVER to heat your animals water with a high voltage 110 Volt heaters as this practice regularly kills an estimated 20,000 animals annually once the high voltage heater gets a crack in the electrical insulation material! Great for dogs, cats, horses, cattle, etc.

WARNING: If you run ANY of these elements dry and without water the heating element will burn out!!!!!! You MUST always have them submerged in water at ALL times when they are powered up!


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
  • 180 F = 82.22 C
  • 190 F = 87.778C
  • 200 F = 93.33 C
