Solar iBoost+ Wireless Solar Immersion Heater Controller
Product Description
The Solar iBoost+ Wireless Solar Immersion Heater Controller is the UK's top-selling PV immersion diverter, trusted in over 150,000 homes to harness excess solar energy for free hot water heating. This intelligent system automatically detects surplus power from your solar PV or wind setup and diverts it to your immersion heater, reducing reliance on gas or electric boilers and slashing energy bills. With wireless communication between the sender clamp and main unit, it's easy to install without extra wiring. Featuring a clear savings display, programmable timers, and boost functions, it's ideal for UK households with hot water cylinders, promoting net-zero living by maximising self-consumption of renewables. Compatible with battery systems and optional remote monitoring via the iBoost+ Buddy.
