Diy prototype solar thermal hot water for my Camper Vans

Описание: This is a prototype solar thermal hot water collector using stuff I had laying around in my workshop. I hope to use it in my camper vans, weather permitting!

The collector will be too small and inefficient to use in the Winter but from April onwards should easily produce a gallon or so of water for doing the washing up etc and on really warm days using a recirculating pump it may even be able to heat water in a calorifier given enough time. This version uses 15m of black domestic hose.
