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.
