solar water heater for ML
Hi Ml, I have some photos of our new solar water heater for ya :) (ignore the ugly roof which seriously needs replacing)
There are two solar panels with the tank at the top there
You can see the copper collectors behind the glass here
Closeup of the glass, this is the new solite glass that they use now
this is the inlet and outlet pipes - (nice work the way they just punched a hole to put the pipes through, pffft)
Basically how it works is the water circulates through the collectors and into the tank, out of the tank and back through the collectors and just keeps recirculating by thermo syphoning. The tank is always full and there is an inlet and outlet valve so whenever you use the hot water there is more water going back into the tank and somehow this creates pressure to push the water out. There is also an overflow pipe in case the pressure builds up too much in the tank and that runs down the outside wall of the house just below.
