The Monday Experiment
Today’s experiment involves learning how much heat comes from a little plastic panel!
Now of course this will be old hat to those who have done this before but apart from heating up the hosepipe in the sun this is as near as we’ve gotten to heating the hot tub. What you see above is a plastic sheet with tubes in it, a small 12v pump, currently running off a battery but will be run off the sun (that side is already sorted – I have plenty of spare power) – and a bucket full of water.
