Would You Like To Save $20/mo. with DIY Solar Water Heater?

I save $20/mo. on our water heating bill by installing a solar pre-heater made of 200′ of garden hose on my roof. From Amazon I bought two 100′ GILMORE 3/4 inch FLEXOGEN hoses (withstands 500 psi pressure), laid it out n garage roof, hooked it to the cold water pipe that goes to gas waterheater. Now all cold water to the waterheater is solar pre-heated. I installed 3 shut- off valves, in case I want to take the solar heater out of the system. One at the beginning of the garden hose loop, one at the end, and one in the coldwater line between the beginning of the solar heater loop and the end. It cost me $140 for the hose and less than $60 for the rest.
At $20 savings in gas a month, it will have paid for itself in l0 months. To use mostly solar-heated water, we don’t use hot water before 10 or after 4.
I did this 3 months ago and the gas waterheater hasn’t been on since. The solar heated water is 135F, and the gas waterheater is at 125F. We always get 135F water at the faucet

so you designed a heat exchanger, not too shaby. however it is time restricted and therefore not functional.
