Intelligent Immersion Ltd - Alton

I have been running the WiFi version of this since 2014, during the months of April/May to September it diverts sufficient surplus solar generated electricity to heat the hot water tank in our 4 bed semi so I can turn off the overnight heating element. It paid for itself in around 2 years. It is very responsive to changes in solar generation or household load so will cut in or out when the sun comes out from behind a cloud or the kettle goes on. I bought the version with two add-ons - an extra relay which I use to divert the solar surplus to a panel heater in the kitchen via an Energenie smart socket once the immersion tank is up to temperature plus an additional energy monitor which tracks consumption of our night storage heaters. Finally I can track generation and consumption activity via either via an online portal or through an app. Although there is a bit of configuration to do at the time of purchase, UK based technical support is readily available. In summary, the unit operates flawlessly to the extent that I have bought a second one which is installed in a rental property, the only fly in the ointment is the web based portal , it provides the information you need but is not as polished as it's competitors however to it’s credit it does allow other systems to be controlled which is how my Energenie smart socket is turned on and off.
