An immersion controller is a device that can help you save money on your hot water bill by automatically turning on your immersion heater only when it’s most cost-effective to do so.
Off-peak immersion controllers: These controllers take advantage of off-peak electricity tariffs, which are typically cheaper than standard tariffs. The controller will turn on your immersion heater during the off-peak period, when electricity is cheaper, and heat your water for the day.
Solar immersion controllers: These controllers are designed to work with solar PV panels. They work by diverting excess solar energy that would otherwise be exported to the grid to heat your hot water. This can be a great way to maximize the benefits of your solar PV system.
How does an immersion controller work?
- A sensor that monitors the temperature of your hot water tank.
- A timer that controls when the immersion heater is turned on and off.
- A control unit that processes the information from the sensor and timer and sends signals to the immersion heater.
