any idea for a solar heater for a washing machine only ?
probably 15 -20 gallons ,
I am thinking 3-4 plastic tubes at an angle for gravity feed ,
connect the tubes at the base with an on/off drain
and at the top where the water hose is connected ,
I do not mind "caveman" quality as long as it works,
and its not that hot here near the beach in Los Angeles , 70-75F ,
so the water needs to heat for 3-4 hours before using.
And will the plastic pipe leave a smell on the clothes ?
thanks for your ideas
