the old up on blocks trick.
watched a utube video where the guy builds a hot water heater
out of a piece of white pvc drain pipe. HUH?
All he did was attach a jig to his table saw and rip the pipe in half length-wise ~twice~ once on each side so he now had two 10 foot ( ) which he lined
with peel and stick reflective mirror foil cut into 12 inch lengths.
the water pipe sits at one third the radius and what you have is a parabolic water heater ......the water pipe is threaded thru holes you make in the end caps with one support block in the middle. you cover
it with glass .....or lexan .... pretty cool, when the suns shining...
the hot water on demand electric tankless hot water heaters were $228 ( smallest one) at home depot.
