## Description

DERNORD 36V 1200W Stainless Steel Heating Element Immersion Heater Submersible Water Heater Element with 1 Inch NPSM Fitting Double U Type - desertcart.com

Review: Boiled a lake - Fairly solid. I would say that it's a little underpowered for application (bought 50x through company to boil an acre large lake), but after a month and $10000 spent on electricity it worked like a charm! Lifespan: Does not run out given that you keep it in distilled water. Ease of installation: Very easy, even a child could do it. Fit: Large, easy to fit.
Review: Go green, use the power of light - I split these and made two out of one. With each one being 600 watts. Using a 80 gallon water heater. Also added a 3/4 element. Plenty of hot water.

## Questions & Answers

**Q: No instructions... Is there a positive and negative? Does it not matter? I'll be wiring this directly to a solar panel.**
A: It doesn't matter.

**Q: Can I use this for a 24v 1200watt dump load?**
A: Yes you can use 24v but it will only use 460 watts.  Power equal volts^2 / resistance. These are 2.5 ohm elements, 1.25 ohm when in parallel.

**Q: Too many products these days have no instructions or product info... Does this product come with either?? Thanks**
A: As far as instructions I'm not sure what you are looking for. It's a 36vdc heating element, you connect the 2 power wires and it does the rest. The box has the wattage, voltage, and dimensions on it. If you are looking for amperage its 1200W / 36vdc = 33.3 amps. This isn't perfect but it is very close. For the pipe connection you apply a form of thread sealant and screw it in, then check for leaks. Hope this helps

**Q: When you connect direct to solar panels. Is higher volage from panels a problem. The panels I am looking are 40 volt.**
A: You should be fine using 40v panels.  Wire in parallel and watch your amps more than the volts.  36v 1200w element has a 33amp limit, so add up the amps produced on your panels and don't exceed that......and don't forget to protect the whole thing with a 40amp fuse or breaker in there.

### ⭐⭐⭐⭐⭐ Go green, use the power of light
*by G***E on September 1, 2021*

I split these and made two out of one. With each one being 600 watts. Using a 80 gallon water heater. Also added a 3/4 element. Plenty of hot water.

### ⭐⭐⭐⭐ Element lugs WAY too small and WAY to close together
*by T***Y on July 30, 2021*

This is a 36v, 1200watt element. That means the max amps on the wire could be 33amps. To run 33amps DC any distance at all, you're gonna need #8 wire minimum, and maybe heavier. The PROBLEM is the lugs on the element are TINY....haven't measured, but they look like 3/16" studs (or smaller), and WORSE, they are very close to each other. Try to find a lug to go on the end of a #8 wire with a small enough ring or spade connector that it doesn't bridge the small gap between the positive and negative studs on the element......REALLY had to do ! Most are made for 1/4" and go up from there. I finally found some ground lugs at an electrical supply store that take a #8-14 size wire, and mounted them on the element studs to for a place to connect the wire. Whoever designed this sure didn't take into consideration HOW THE HECK TO ACTUALLY CONNECT WIRES TO IT !! Edit: After 3 weeks, the RELAY I had wired between the panels and the element failed. I used a relay (rated at far more amps than my panels put out) controlled by the tank thermostat to control water temperature. I thought initially the element had failed, but it is fine. Waiting on a Bosch relay instead of the cheap one I had from you-know-where. Right now, I'm running six 175w 5a panels into this element in a 28gal tank. My panels are West facing and only get about 1/2 day of sun, but the tank temperatures are running in the 175 degree range with little water used. I'm well pleased with this element.
