Immersion heater optimisers detect when you are exporting energy to the grid and send it to the immersion heater in your hot water cylinder to give you free hot water. The feed in tariff export payments are paid at 50% of what you produce no matter what you export so using as much as you can yourself will maximise your payback. The system is very simple to fit and works via a wireless link from near your meter to your hot water cylinder.

The iBoost+ can also link to a wireless “Buddy” which allows you to monitor when excess power is available via a traffic light system so you know when to turn on appliances to maximise your free electricity usage.
