DIY solar hot water controllerthe 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!!! the analogue ‘lash up’…here’s the first attempt…it’s not pretty but it sort of did the job that was required of it (thanks to tony)…there’s an analogue sensor (can’t remember which one) and an ADC and that feeds into the parallax propeller chip which decides whether to turn on the wilo pump or not using delta T.
