Does an immersion heater stay on all the time?
This is a very common myth. But in fact, you really don’t need to be heating your water all the time. Your immersion heater or boiler will heat up hot water which is stored in a tank. As long as the tank has a good insulating jacket, it will keep the water hot all day, without needing to be constantly reheated.
Do immersion heaters turn themselves off?
An immersion heater with thermostatic control will automatically turn itself off when the water reaches your desired temperature. Then turn it back on if the temperature cools too much.
Can I put a timer on my hot water cylinder?
The Honeywell Hot Water Timer lets you set your hot water cylinder to heat during daylight when your solar system is creating electricity, reducing the draw on the grid and saving you money in electricity bills – especially for those big-ticket items such as swimming pools and spa pool.
How do you use immersion heaters efficiently?

Why does my immersion heater have two switches?

Do immersion heaters use a lot of electricity?
Immersion heaters use electricity to heat water, which is considerably more expensive than gas. For example, 1 kW of gas will cost you around 4p, while 1 kW of electricity will cost around 15p. That means a 6 kW immersion heater would cost 90p an hour to operate, substantially more than operating a gas combi boiler.
Should I leave my immersion 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).
