We’re always on the look out for simple, fun solar projects and this is one, that, with a little imagination could be put to good use.
If you are off grid then this could be a great way to supplement your hot water supplies.
A solar water heater heats up the water from the sun’s radiation giving you the option to then use this hot water in your home.
The basic method of heating water with the sun consists of a series of pipes that are contained within a darkened glass fronted frame. Water flows through the pipes into an insulated tank in a continuous loop until the water is hot enough for use.
The frame is placed in a sunny spot to maximise the level of collected sun and heat.
Let’s take a look at one option for a DIY home solar heater project.
You’ll need to get or make a frame, size is up to you, but it will need to be about 2 inches deep.
The back of the frame should be made from some metal sheeting, corrugated sheeting is fine and this should be painted matt black.
You will need some high temperature water tubing (PEX plastic or similar) it needs to be flexible as you’ll be bending it around. This tubing should be black or you should be able to paint it matt black.
Now, taking the tubing you need to place it in the frame, against the metal backing, winding it backwards and forwards in an ‘S’ shape. Try to get the ends of the tubing at the same end of the frame ( ie at the top or bottom). Make two holes in the frame so that both ends of the tubing stick through the holes.
