Smart Home Energy 
If you have roof solar and a hot water tank, Solar iBoost+ diverts surplus generation to the immersion heater instead of exporting for pence — free hot water, less boiler use, and it works alongside battery storage.
Problem it solves
Diverts excess solar PV generation to heat your hot water tank instead of exporting to grid at low rates, cutting water heating costs and reducing boiler use.
Who it's for
Homeowners with roof solar PV and a hot water tank (immersion heater) who currently export surplus generation and want to use it for free hot water instead.
Why we recommend
A great solar diverter which is also compatible with battery storage systems (will divert surplus after battery is charged).
Savings
- Typical annual saving
- £150–£300/year depending on solar array size, household hot water use, and export vs import tariff differential
