Is solar water heating system worth installing?
I am thinking of getting solar water heating system. I have heard some negative comments on usability and ongoing maintenance. I would like to hear from anyone who has any personal experience in solar water system.

No solar water heating on account of the fragile glass tube systems normally used.
We get hail storms every year that would probably wreck them. Would need something that can hold up to nasty weather here.
I did obtain a roughly 1 meter by 1 meter piece of glass that's about 8mm thick.
Might be able to do something with that.

I would stick with PV solar to capture energy. Get a heat pump water heater to use the electricity efficiently.

I already have a heat pump water heater.
An old R-22 charged ecotech unit from the early 2000.
When it dies I will pull it out and take it to the local hvac shop and rebuild it because you can't get them build like this any more.
Unless some one starts building new add on units like my old ecotech in the mean time.

I tested my utility water performance.
At no flow utility pressure sits at 65 to 68psi.
Turn the water on Utility delivers just over 10gpm at the end of a 30 foot 3/4 inch garden hose. On the other end of my house the water pressure was reading 40psi.
I also have a little fire hose nozzle to put out grass fires, water trees and what not. It does close to 7.5 gpm at 55psi on the other side of the house.

I would like to be able to efficiently exceed utility performance.
