Hey guys!

ive build my own solar heater and I’m using an old copper low pressure geyser as the storage. It works super well- but mounting it to work on thermosyphon alone isn’t easy (still need to keep it out of view). So I want to add a tiny solar inline pump that will turn on when the sun is out and help circulate the water.  I can find a number of options at quite a price but I need the most basic system- no switches or anything. Just a pump that can connect directly to a small solar panel and circulate. 

Thanks for any advise!

You get small 12v DC pumps that run off a 10w solar panel that should do the trick.

Thanks for your reply. Any particular place to look for one? 

Google? Try TAKEALOT and the other online stores. I'm not sure who physically stocks them.

Thanks. Yeah I’ve googled ALOT. but I’m not super clued up of what little motors can run on solar direct or not.  The solar websites available obviously have them. But sometimes the price negates my electrical bill 

You need a nice hot shower before you go out to save the planet, so cost should not be a consideration!

Try Sanitary centre

Thanks for the replies guys. I ended up finding a pump and a panel on bidorbuy for a great price. I’ll report back on how it works once I get it. 👍
