Hot water & underfloor heating from solar panels using willis heater and solar diverter

A video showing how I've temporarily set up my Solar PV / solar panels to heat up the pressurised hot water cylinder and wet underfloor heating system when there's excess solar pv. I have set this up in my future workshop, it's where I am temporarily living whilst I continue to work on the abandoned coach house.
The solar is diverted using an "eddi solar diverter" & heated into the UVC with an immersion heater or pumped around the under floor heating using a willis (replica) heater.
This is the simplest & lowest cost method of doing this I could find and it was super enjoyable setting it up,
although I'm looking forward to doing it all properly.
