What is an Electric Hot Water System?

An electric hot water system is a water heating unit that uses electrical elements to heat and store water for household or commercial use. These hot water systems work by heating cold water from the mains supply using electrical heating elements, similar to how an electric kettle works, but on a larger scale.

The hot water system stores heated water in an insulated tank, keeping it at a set temperature until needed. When someone turns on a hot water tap, the stored hot water flows out, and new cold water enters the bottom of the tank to be heated. This process ensures a continuous supply of hot water throughout the day.

These hot water systems provide hot water for many daily activities. In homes, they supply water for morning showers, washing dishes, and running washing machines. Small businesses like cafes use them for cleaning and food preparation. Larger commercial settings might need them for industrial cleaning processes or manufacturing.

Most modern electric hot water systems heat water to around 60 degrees Celsius, which is hot enough to kill harmful bacteria but not so hot that it risks scalding. They come in various sizes to match different needs, from small 50-litre units for apartments to large 400-litre hot water systems for big families.
