How Does A Hot Water Cylinder Keep Water Hot?
If you own a hot water cylinder, it is important to be aware of how it works. It can provide much-needed assistance with maintenance and saving energy. At its most basic level, a hot water cylinder works by heating up water that sits inside an insulated tank. The water is heated by an energy source, usually either electricity, gas or solar power.
Once the water reaches the desired temperature, the cylinder switches off the heating element but retains the heat energy stored in the water due to the thick insulating outer jacket. This keeps the hot water hot until you turn on a hot tap and draw it out of the cylinder.
