Wiring hot water systems, who should do this?

The wiring of any machinery, product or system should be done by an electrician. Although, other tradespeople are also qualified in being able to set up wiring for hot water systems. If you are planning to change the size of the tank or the style of the hot water system, then you should get an electrician to analyse the wiring, contact information here, to make sure the system is functioning properly and is able to deal with the change in power load.

If you are in the process of replacing your hot water cylinder than you should make sure an electrician is in attendance. Especially if you are moving towards a system that requires a higher-pressure unit. Older cylinders often have a lower pressure unit and the old wiring would be suited for that cylinder. However, the newer cylinders would have a pressure unit which is higher and would require new wiring as the old wiring would to be too weak to safely power the higher load of the new cylinder. Old and weak wiring on a new cylinder can lead to electric shock, fire and the water not being heated at all.

Water heater next to a house

An electric hot water system, also known as an electric hot water heater works mostly like a natural gas storage system. The cold water is piped inside the tank through the cold-water pipe. The water inside the tank is then heated. The heated water then escalates to the top and is released through the hot water pipe when a hot tap in the house is turned on.

Installing these systems is quite a common job for electricians.

There are three parts of the electric water heater that crucially depend on proper wiring of the system. They are the electric supply tube, the upper heating element and the lower heating element. These three parts are what generates the heating of the water inside the tank. Both the upper and lower elements depend on proper wiring so that they can perfectly heat the water to the temperature that is set on their respective thermostats. The lower thermostat obviously sets a temperature for the lower element and the upper thermostat sets the temperature for the higher element.

Many electric hot water systems do not store any hot water, rather they operate by heating the water when the hot tap is turned on. So, as soon as a hot water tap is turned on at any bathroom or sink in the household, the hot water system begins to heat the water that has come from the cold-water pipe. That is why when you are on any of the upper floors of a house it takes around fifteen seconds after you turn on the hot tap for hot water to come out of the faucet.
