Re: Question?
I've looked into this but haven't jumped at anything yet. The closest things I've seen have been either on openenergymonitor (looked too complicated for me) or I found a thread on a forum: http://www.electriciansforums.co.uk/central-heating-systems/23969-immersion-heater-pv-electricity-15.html (jumping into the middle of it!) in which some people seemed to be offering to sell a semi-ready-built system for a reasonable price.
