An electric hot water system is a hot water tank that uses power to heat water just like a electric kettle does. Smaller under bench tanks are great for the office while bigger tanks are made for the home. Electric hot water systems have a thermostat built into them and this controls the electric element that heats the water when the temperature of the water gets below preset temperature that its set at. Always have the temperature on any storage hot water system above 63 degrees Celsius due to legionnaires disease. The electricity heats the element and this in returns heats the water within the system. Once the water is heated thermostat turns the power off to the element and that’s it. That is simplest way can explain how a electric hot water heater works


Why choose a electric hot water tank?

Even now days some homes, offices even caravans and rv’s don’t or can’t have gas connections so electrical is there only choice. A lot of older homes had a choice of either electric or wood fired hot water systems called donkies. Even now days there are still a lot of wood fired hot water tank set ups around the place as a lot of people going away from using electrics for heating or at the very least running solar to help with the cost.

Unless building a new home a lot of the time it’s not worth changing over from a electric to any other type of hot water system due to cost of install. Most steel hot water tanks have a life span depending on water quality of around 10 years so working out the cost of changing over to another resource and the cost of power you will have to do the sums.


Some brands of electric hot water systems.

There is quite a few different brands and sizes of hot water systems on the market these days and picking one can be hard. Most times when the tank gives up the ghost more then likely just replace same as whats there. If in australia once you start to change sizes and different types ie going from electric to gas or 125 ltr to 300 ltr say then by law there must be tempering valve installed in the hot water line to control the temperature to the bathrooms and ensuites. Below is a list of some major brand hot water heating systems
