Hot Water Systems Explained: Everything You Need to Know
A hot water system works by heating water and storing it or heating it on demand, so that hot water is ready whenever a tap or shower is turned on. Most systems use either electricity, gas or solar energy to heat the water, with a thermostat controlling the temperature so it stays within a safe and comfortable range. Depending on the type installed, the water might sit in an insulated tank ready to use or it might pass through a heating element the moment it's needed.
