I am looking to replace my solar hot water heater only. I have asked several companies for estimates but they all seem to want to sell me the whole system. Little bit nervous not sure where to buy as my home stores don't seem to have decent pricing or knowledge. I have replaced a conventional water heater before but not sure what steps to take for solar. Thank you very much in advance for any help that can be given.
I live in Sunny Arizona this is what I have now.
17 year old 82 Gallon State Solar/electric water heater w/ Goldline differential. Don't think I need such a large tank since I am only one person and don't use much hot water. I am open to just getting a conventional water heater w/ timer but would like to replace solar heater if I would get ROI in a decent time.
I guess questions that I have are what would you do conventional 40 electric w/ timer or replace solar unit? I am only one person.
Where can I find out more on how to replace solar unit. What all the pipes are and steps.
Local stores only have one solar model its pretty expensive what are my options. Don't think I want to spend more than $800.
If I detach glycol lines on top will it dump all over? Where do I get replacement glycol?
Do I need to replace differential? If not how do I make sure its set up correctly. It has been messed with in the past.
I have pictures of what I have here:
