## 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.
