I inherited a solar water heater from a previous Chinese owner. The solar water heater has some trouble now. Its within the 3 year warranty. Company name on the heater is Sunfire located in Capitol Heights (http://www.sunfire-solar.com/), Maryland. When I call the company, first thing they say is that they never sold solar heater to an english speaking person!!
I told them the situation and they asked me to call the technician who installed the product since he took the money when the product was installed. The technician says that he trained the other folks and he is no longer a partner. Basically, I am getting a run around.
So I asked the current company which is Solar Supplies International Inc to come and fix the issue. They are asking for $250/ for the gas and work even though the product is under warranty.
Not to mention the need to explain the issue 10 times since they hardly speak english.
I thought of doing the work myself and find out that the assistant tank is having some issue with the valve. So I get the piece out and go look for one in Home Depot and other local plumbing companies.
No one carries such part.
Only place you can find them on internet is Alibaba.com to be shipped from China.
Basically, the solar water heaters are shipped from China and these small businesses install them with random warranty and will not guarantee the work.
You are stuck with this $10,000 elephant that is expensive to maintain compared to cost reduction you get from it.
I am still in search for the part and a decent reason why they have an assistant tank first place.
But in my opinion, dont buy these made in china solar water heaters.
