Energy is expensive here in Brazil so I decided to save some money by making a Solar Water Heater. In Brazil water is usually heated instantly with 5000 watts of electricity in the shower head. This is the same amount of electricity as running your microwave for 1 hour to water for you 15 minute shower, or turning on 50 one hundred watt light bulbs at the same time. Needless to say, it really adds up on your electric bill (and is also a little scary).
I wanted to do it cheaply. In Brazil copper is very expensive so I made it with PVC. I was able to come up with a cheap back up heater for cold days – a $30 ‘bucket heater’ with a built in thermostat.
PVC is not the best conductor and it does have temperature limitations. So I did come with some ideas as how to make it work.
