Finally completed solar hot water system.
Not having any working samples to look at,
it took some time. I customized
design for existing conditions and soldered
all copper. System is calculated to
estimated consumption, local solar azimuth
and winter sun solstice to maximize the
performance throughout 12 months.
Main components are:
*40 evacuated glass tubes on collector
*closed loop 3/4" insulated copper piping
for heat transferring glycol mixture
*two circulation pumps and valves
*additional 80gallon hot water tank to
existing 95ga hot water boiler
*temperature difference controllers
We have had 100% solar domestic hot water for three weeks by now. There is
constant reserve of 140...150 degree Fahrenheit hot water. Con Edison inspectors are
expected to pay a visit soon to see why my house natural gas consumption is irregularly low :-)
Hope to see more of these systems on the rooftops in NYC to cut down overall
fossil fuel consumption. Plus it PAYS OFF!
Here is a Iphone snapped pic of collectors with my son Tormi.
Special thanks to Jimi, Kadri and Tormi for help.
