Johnny Said:

Are solar power water heaters obsolete? Some repairman said we should just replace it with a normal one.well?

We Answered:

Ok
Repair men are salesmen as well.
we need to make money.
but some take it to far
this guy may not know how to install solar hot water
so he will try to sell you anything he knows how to install. so he goes home with some money.

(tip 1)
I have never repaired a leak and the hot water stopped working

(tip 2)
solar hot water is available

(Tip 3)
look on top of your hot water tank and one side says cold
turn the valve on because he may have shut it off to make the repair to the pipe and never turned it back on.

(Tip 4) check all valves you can find (turn them on and off see what they do) so you know in the event you get another leak.

well you have the internet
and I have your back

James Said:

which is better for holding heat for solar power, water and granite, or just water?

We Answered:

water does have a higher SH, by a factor of 5. although since the density of granite is about 3, that means the volume SH is closer to water.

The only reason I can think of why you would use granite is that unless the water compartment is sealed, the water can evaporate and take the heat away.
