Well what can I write about water heaters. Well they heat water. Sorry, a bit of a Homer Simpson type answer about them but it shows you how interesting water heaters can be.
They are not really something you can get too exited about but they are something we cannot easily do without. We all want hot water. We need it to wash and bathe in and we need it to clean with. Some of us want to use it to warm our pools up, wash our cars, heat our homes or sit in our hot tubs but at the end of the day we all want hot water and the only easy way to get it is to use a water heater.
So thinking about it then, what types of water heater are there? Well there are four main types but most of us will only need to use one. I have three but I tend to use only one at a time, two at the most.
Solar water heaters. These types of water heaters rely on the power of the sun to heat your water. How efficient they are depends on the amount of sunlight they get so this usually depends on where you live. The more sunlight the better and the more intense the sunlight the better and if the climate is hot in the first place then the water is sort of pre heated to ambient temperature...
