Product Features
48V 1500W Element : These elements are made from stainless steel to prevent any corrosion so are suitable for use in virtually all types of water tank
Product Application
→ Great for use heating water in domestic hot water cylinders or water tanks in caravans,boats,workshops etc. Can also be used with waste vegetable oil in the the manufacture of biodiesel, and for home brewing etc
→ Can also be used with waste vegetable oil in the the manufacture of biodiesel, and for home brewing etc
→ These can also be used to prevent water freezing during winter months in livestock drinkers or raised ponds by connecting one to a large 48v battery recharged by a large solar panel or wind turbine, just use a basic 5 degrees c normally open thermostat and when the water temperature gets near five degrees the heater will automatically come on and warm the water by a few degrees before switching off again, one could also be used in the water storage tank in your loft if its prone to freezing in the winter months
NOTES
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.
If used as a diversion (dump) load, such an element is connected to the batteries via a charge regulator. When the regulator detects that the batteries are fully charged, it diverts the generated electricity to the element which heats water.

One thing I wish was different is that the input terminals are very close together and I have t be very careful or I will short out the power source which is a battery bank.

I received this unit and done some testing on it before fitting into my installation. It has two heating elements each element is at 3.5 Ohms and in Parallel 1.8 OhmsIf I calculate this 48Vdc , Amp: 26,666666666666664 and and 1.8 OhmsThe maximum output 1280Watts and not 1500Watts as advertised.

Happy, happy, happy - I ordered this beautiful stainless 48 volt heating element to install in a beer keg. I know some folks like warm beer - I don't; I'll be making the last water heater I'll ever need out of it. I've cut the lid out of the keg - need to drill for element and anode, design the circuit, and do a bit of fabrication and welding. Life: eats up all my time. The element has been sitting around for a week or so now - decided to test her out this evening. I grabbed a 14 awg SAE connector, a half gallon mason jar, filled it with water, crimped on some ring terminals, dropped the element in the jar, and hooked her to 50AH 48v bank. Yep - I know 14 gauge wire is way under on the current carrying capacity - just a quick test – didn't plan on taking a bath. Quick test it was – couldn't have been more than 2 or 3 minutes and the water was at 150 degrees, and I was smiling. During heating amp draw was between 25.? amps and 27.? amps - so right around 1200 to 1300 watt range. I couldn't tell if it's low on watts due to the element or my 14 awg set up. (or my 44.4 volt bank @ 47 volts) Could be something else I need to do to the circuit – I'll study up on it before I build it. Anywho – I hope it does run at 1250 watts – I think that will heat the water plenty quick enough for me, and I prefer the slower drain / amp draw on batteries. That's the best I can do ya right now – be back after build with some more data, data, processing.The element itself looks and feels (hefty) very nice. It has a substantial / solid chunk of stainless that the terminals are mounted in, and is hex machine cut for a 1 1/2” wrench. The threading below looks to be 1” npt. Nice pliable (silicon ? Teflon?) eighth inch washer around the threads.So far – 5 Super Novas for The DERNORD 48V 1500W Water Heating ElementThanks for Reading - Have an Incredible Life!
