Please forgive my sounding nosey. The reason was to get an idea of the natural resources that may or may not be present for you to utilize. An example might be manure. A pile of manure, with a pipe coiled inside of it, covered with black plastic could heat water. These type of things.
Yeah, electrical fires, I here that a lot. If an electrical fire is caused, it happens because somebody, someperson, didn't adhere to the NEC or lightning struck. I have actually seen where two neutral wires on a 120 vac, 20 amp lighting circuit in a steel box in the ceiling where not made properly and they got hot enough to smoke badly. This scared the people in the house and they called the fire department which in due course, pulled their meter and would not give it back until the electrical was corrected and inspected. All of that could have been prevented simply by someone twisting those two neutral wires together tightly before screwing on a wire nut. It was in a box though and that is what probably kept any wood from catching on fire. An arc fault breaker would have helped also but the house was old enough not to require them according to NEC. Another example is where somebody changed a 15 amp fuse on 14 gauge wire to a 30 amp fuse. There was nothing left of that home. In a sense, this made the 14 gauge wire the "fuse" but instead of blowing harmlessly encased in glass and metal, the wire got hot enough to set wood on fire and burn the house down. I could go on all night with these examples. The reason I am bringing them to your attention should be obvious. In the wrong hands, even small amounts of electricity can be extremely dangerous. Just look at the world today and why there is such a thing as non-polluting renewable energies. Ok, enough said about that.
It is possible to safely heat water with a deep cycle battery bank.
http://www.survivalunlimited.com/diversionloads.htmBut lets think about this for a minute. Take a look at the SJH12600 element. Thats 600 watts at 12 vdc or 50 amps at 12 vdc. It claims to be able to heat 15 gallons from 75F to 120F in 5 hours. 5 times 50 = 250 amphours at 12 vdc nominal. That would mean nothing less than 4 - Trojan T-105's wired in series/parallel for a total of 440 amp hours at 12 vdc nominal. After heating 15 galloans of water it would more than 50% dead. To replace that with PV in your region it would need a PV array of no less than 600 watts at 12 vdc nominal and 5 hours of clear sky's and sunshine to reach 100% for the next 15 gallons. Also there is the need to change the thermal switch because the ones on your water heater are not rated for 50 amps at 12 vdc and the size of the wire would have to be no less than #6 awg cu. and it would need protection with a fused disconnect rated for 12 vdc nominal.
How many thousands of dollars are we looking at here for 15 gallons of hot water per day if lucky?
It would not be environmentally benign as solar power but, but maybe you should look at the cost of having a gas fired water heater and an LP. or Nat. gas service installed. Then as time and money allow, having a proper solar thermal water heater installed to reduce dependence on that gas. Who knows maybe even an air handler or radiant hydronics to heat the home. One thing is for certain, all of this renewable energy stuff is extremely expensive but before there prices come down the established energy infrastructure will raise theirs.
You know pour water in, cap off& heat it up. pump out with air ?? isaac thank you
