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. Technical Details Voltage:36volts Wattage:1200 watts Item Weight:11ounces Product Diameter: 8mm Tube length: 7.5 Inch Screw Type:1"NPT Color:White 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. ## Features - 36v DC heater connects with batteries, solar panels, hydroelectric generators and wind turbine dump - 1" NPT flange fits USA standard water tank or your own custom heater tank - UL and cUL listed to the safety standards - Stainless steel surface has electropolish - Supplied with silicon sealing washer which is flexible and waterproof ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Dernord | | Package Dimensions | 28.6 x 7.5 x 4.2 cm; 307 g | | Material | Stainless Steel | | Voltage | 36 Volts | | Wattage | 1200 watts | | Batteries included? | No | | Batteries Required? | No | | Item Weight | 307 g | ## Images ![36V 1200W Stainless Steel Heating Element Immersion Heater Submersible Water Heater Element with 1 Inch NPT Fitting Double U Type - Image 1](https://m.media-amazon.com/images/I/51J2y-YRIJL.jpg) ## 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Boiled a lake *by D***E on 29 March 2025* 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. ### ⭐⭐⭐⭐⭐ Go green, use the power of light *by G***E on 1 September 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 30 July 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. ## Frequently Bought Together - DERNORD 36V 1200W Stainless Steel Heating Element Immersion Heater Submersible Water Heater Element with 1 Inch NPSM Fitting Double U Type - Beduan 1" Female Bulkhead Water Tank Connector Stainless Steel Thru-bulk Fitting - DERNORD 48V 1500W Submersible Water Heater Element Immersion Heating Element --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/280417533-36v-1200w-stainless-steel-heating-element-immersion-heater-submersible-water](https://www.desertcart.us/products/280417533-36v-1200w-stainless-steel-heating-element-immersion-heater-submersible-water) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-25*
