Solar Water Heater

Anyone have solar hot water experience?

Looking at hot water for outdoor shower. I have done a couple of outdoor showers over the last year.

The customer wants a direct passive system. I am thinking of going with the six foot solar tubes daisy chained to get 40 gallons.

40 gallons at 135 degrees? Should run a normal shower (unless your my wife).

Ive made solar pool heaters out of black poly pipe before. First one was a house I rented yrs ago and the pool heater was dead. Rent was cheap and I didnt want to risk a rent increase by asking the landlord to get the heater fixed. Plumbed a roll of 1-1/2 poly into the return. Worked like a charm.

Poly pipe in direct Sun, looped on the roof or on the ground makes scalding hot water for an outdoor shower.

On-line I have seen many designs. I liked a design that incorporated condensing coils into a solar oven type design.

Granted poly laying in the sun makes some pretty hot water, but I am concerned about maximum temps for poly pipe and water toxicity.

better a butyl-based material with enough additives to tolerate long sun exposure

I have seen outdoor showers that use a coil of poly laying in the sun to heat up the water. It was on the side of a shed at a house on the beach so they could wash off the sand. It worked pretty well.
