But you have changed your mind about going with your friends to a summer vacation like going swimming or camping out in the woods. So, what you are looking forward is to make your idle time productive. How about making your own DIY solar water heater? Bear in mind that winter is just right around the corner and it is the next in line with autumn and summer, right? Your family will certainly need all the hot water for that season and heating up water using electricity is a waste of money so, why not build your own solar water heater and heat all the water you want?
