How does an immersion heater work?
An immersion heater works similarly to that of a kettle. Within the hot water cylinder, which is the main body that stores the water, is an electric resistance heater element. This element is “immersed” in the water, which is where it gets its name from.
How does a dual-element water heater work?
With a standard electric water heater, one heating element is used to warm up water inside the tank (in a natural gas system, this is accomplished with a burner). With a dual-element water heater, there are two heat elements – one on the top and one toward the bottom of the tank.
What is a dual immersion cylinder?
A dual immersion cylinder has 2 elements, one at the bottom for using with off peak electricity to heat a full tank of water cheaply and a short one at the top to heat a small amount of water on expensive electricity if necessary as a top up. The top element is usually wired to a switch marked "Boost". Thanks.
Are immersion water heaters any good?
It has been said that they are not the most affordable options, especially for family homes, where you need to have access to a lot of hot water at all hours of the day.

How does a dual element immersion heater work?
Each element has its own thermostat, and only one element runs at a time. The top element turns on first to start the warming process. Once the water in the top half of the tank reaches the set temperature, the top element turns off, and the bottom element turns on to heat the rest of the water.
Why do I have two immersion heaters?

Should I leave my immersion heater on all the time?
Do not leave your immersion heater running all the time. No matter how well-insulated the immersion tank is, it will still lose heat and the drop in water temperature will cause the immersion heater to run repeatedly (like your kettle coming back to the boil over and over again).
Do both elements on a water heater run at the same time?
Only one element will come on at any one time. This is known as a flip/flop system. On a 240 volt water heater, there will always be 120 volts to both elements. The thermostat will direct the second leg of the 120-volts to the element to complete the 240 volts required to energize the element.
Why does my house have two water tanks?

Why does my hot water heater only have one element?
Water heaters that are 20 gallons or less typically only have one heating element. Water heaters 30 gallons or more are dual heating element systems. If only one heating element is working in a dual heating element system, the water heater will not produce as much hot water.

How long does it take for water to heat up in an immersion heater?
Depending on the type of immersion heater you use, it could take between one and two hours for water to heat up. This is why using insulating layers can be very beneficial as they will maintain a warm temperature and decrease heating-up time.
Why do you leave the heater on all the time?
This is why some homes will leave their heaters on all of the time so they will always have access to hot water.

This will save you money as you will not have ...
