who sells solar water heaters?

[Seeb]

does anyone know a good place to buy solar water heaters components?

HPM has them but I don't about their price competitiveness.

I'm looking for thermosiphon system which eliminate the electric pump but you need a structurally sound roof. My especially like the Blazing Tube system but no vendor on island-

Other thermosiphon systems are Solahart which I first saw on house roofs 50 years ago looking like a flying saucer. And a competitor model sold by Interisland Solar. Both of these located in the Kaloko Industrial in Kona anchored by HD. I think Interisland supplies a lot of the components like Gexpro in Hilo but i think gexpro handle more electrical parts.

Some interesting stuff on eBay
The evac tubes caught my attention.

Why is it such a pain in the butt to get these things here. You'd think everyone would be selling them

Shipping empty tanks is not cost-effective.

With any luck, shipping will keep going up until local manufacturing is a better deal.

So anybody got the scoops on evac tubes. All I know is it sounds pretty interesting?

if you look on Craigslist you can sometimes run into someone selling a complete system that they didn't use or selling a used system that they no longer want for some reason. But at any rate some good deals to be had. Or just make your own!!! I'd probably use copper. Because of our climate CPVC and PEX are not strong enough and I think it will leak.

So probably under 1000 bucks you could get a decent setup from home depot. Some copper tubes 90's and T's. Material for a box/Black paint/insulation and some double pane glass or maybe a used slider off of craigslist. of course you'll need a tank and a few other things like a check valve etc...etc... not hard to learn how to solder copper. Just up the joint and the solder will get sucked in.

I did make my own thermosiphon system 20 years ago with a $200 discounted water heating panel and an old water tank that I painted matte black. It worked ok then started leaking from the joints. Maybe I didn't preheat the copper pipes enough before soldering.[!]

Also Drainpipe said they can install a thermosiphon unit. My guess is they just order it from the kaloko vendors. Those too heavy for my roof so I rather have the Blazing tube units.
