DIY solar hot water controller


the solar hot water system you can see on this blog has cost approximately £200 all in. In particular the flat plate collector was made out of mostly recycled materials! Here in the UK people regularly pay anywhere in the region of £6000 - £8000 for a system which we regard as inferior. And what's more it has a horrific amout of embodied carbon due to shipping from China. So have a go yourself and we hope this blog will assist you in your system design and construction..
below you'll find the blog area which we're updating constantly with new info regarding the controller...coming soon...a dedicated PCB!!!


glass top

harry (dad) holding glass scrounged from a local glaziers who were happy to help. it was originally a £200 sealed unit that I got for £20 because it’s seal had failed.  was destined for the skip.   because the panel only needs single glazing I’ve only used £10 worth so far so if there’s a need for a further panel then I already have the glass…talking nicely to local building suppliers will almost always pay off!!!
