## Description

Product Features 12V 150W Element : These elements are made from stainless steel to prevent any corrosion so are suitable for use in virtually all types of water tank Product Application → Great for use heating water in domestic hot water cylinders or water tanks in caravans,boats,workshops etc. Can also be used with waste vegetable oil in the the manufacture of biodiesel, and for home brewing etc → Can also be used with waste vegetable oil in the the manufacture of biodiesel, and for home brewing etc → These can also be used to prevent water freezing during winter months in livestock drinkers or raised ponds by connecting one to a large 12v battery recharged by a large solar panel or wind turbine, just use a basic 5 degrees c normally open thermostat and when the water temperature gets near five degrees the heater will automatically come on and warm the water by a few degrees before switching off again, one could also be used in the water storage tank in your loft if its prone to freezing in the winter months NOTES If you have a gas hot water heater you may wish to put an electric unit ahead of it. 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.

## 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.

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. We used this one: https://www.amazon.com/gp/product/B06X3TVD81/ref=ppx_od_dt_b_asin_title_s01?ie=UTF8&psc=1
