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.

Will that be a problem? Denord please.** A: Yes it will . Needs to be covered with water at all times to keep it from overheating . Overheating will damage the unit .needs to be at least 4to6 inches under water at all times .p **Q: What if you have lower amperage? instead of 12, maybe 3-5 amps. will it still work? just not get as hot?** A: Its 12 volts, not 12 amps. If you have 12v and 3 - 5 amps you will get maybe 36 - 60 watts. It won't get very hot. **Q: Can this be used hooked straight to a 100w solar panel?** A: 150w element 100w panel no offense do the math. It will heat but at 12v 150w takes 4 hrs to heat 5 gallons of water so I doubt your getting a solid 5 hrs full output. Not recommended but might limp through. **Q: Is the internal wire heavy enough to connect 24v and get 600 watts (i.e. double the amps)? Thanks!** A: Hi, I don't think it's possible, you would shorten life to the resistance. I recommend that if you are going to use 24V, connect them in series. ## Frequently Bought Together - DERNORD 12V 150W Immersion Heater Submersible Water Heater Element Stainless Steel Heating Element with 1 Inch NPSM Flange - Beduan 1" Female Bulkhead Water Tank Connector Stainless Steel Thru-bulk Fitting - DERNORD Cast Pipe Fitting Stainless Steel 304 Hex Locknut NPT Female 1" (Pack of 1) --- ## 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.jp/products/745444007-dernord-12v-150w-immersion-heater-submersible-water-heater-element-stainless](https://www.desertcart.jp/products/745444007-dernord-12v-150w-immersion-heater-submersible-water-heater-element-stainless) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-29*
