An immersion heater is essentially an element that inserts into your hot water cylinder as either a primary or secondary heat source. In a direct hot water cylinder, it is typical to find at least two immersion heaters to heat the water to the required temperature. While indirect cylinders generally make use of one, making them an ideal back up if your boiler or primary heat source was to fail. With the option to switch on and off, immersion heater thermostats are a convenient method for aiding up heat recovery times for all your hot water needs.
