DERNORD 12V 150W Immersion Heater Submersible Water Heater Element Stainless Steel Heating Element with 1 Inch NPSM Flange - desertcart.com

Review: Great low voltage heater for science experiments! - I used this for my son's science experiment which required heating a tank of water and regulating the temperature to a specific value. This worked great, no leaks thanks to the silicone gasket, and was a safe, low-voltage component. we coupled it with our own homemade temperature controller and it worked great! Would purchase again for any similar needs in the future. The heater is made from high quality materials, stainless steel and has the heating element brazed to the terminals for what looks like a long-life component that should last many years. Note: This heater comes with NO NUT, so you need to purchase one separately if not threading into an existing housing with threads or a nut already in place.

Review: A cheap quick way to supplement hot water. - A cheap Quick Way To Supplement hot Water. just install this element in either the top or lower port to supplement the temp I just used A HF. 4 panel kit about 100 watts. And set up the contact bars to run in series. (Solar Panel current is closer to 24 vdc and travels better A long distance from the source than 12 to minimize loss. ) when you set it up keep in mind you still want to leave the second 220 V element attached as the back up if you don't have enough solar to keep up. we don't use A lot of hot water so I initially installed the low voltage element in the lower port through the existing thermostat and set it at 150 deg. F and Set the top 220 V 2500 watt element at 220 deg. I set it up like this to test everything .the 40 gal. tank held enough hot water to run the dish washer and 2 showers. until finally cooling to lukewarm. so i went to check on the heater and realized i had forgot to turn the grid power breaker back on. I would suggest if you do this at first use a 3500 watt 240 v element in the bottom port set at 140 deg. and use the low voltage element in the top port. and install a mixing valve this maximizes capacity uses less than half of grid power and greatly extends hot water capacity.

## Questions & Answers

**Q: I would like to top mount the element, but a small amount of the tube won't be covered with 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.
