SOLAR HEATING SYSTEM CONSTRUCTION LOG
PROGRESS
REPORT:
October
11: Plumbing solar heat exchanger etc.
The plumbing is
taking forever! There is so much planning and
so many parts!
I am so ready to have all this stuff working!
At least the
weather is staying warm enough that I don't need it yet.
Here is the solar
collector plumbing loop mounted to the wall
with all those
gauges, valves and pressure tank showing.
To the left is
the 80 gallon storage tank that will keep the
solar heated
water hot until needed. The ideal ratio is 1.5 to 2
square feet of collector surface per gallon of tank storage capacity.
(Note that I later added 2 collectors to
improve this ratio).
The big stainless
cylinder in the right image is the heat
exchanger that
will transfer the heat from the glycol filled
collector closed
loop to the water tank plain water.
It is a Secespol
model B130 and you can see a brochure
of the product
line here.
To the right of it you can see the
El-Sid SID10PV
solar powered water pump with it's wires sticking out.
Here it is close-up:
These are extraordinary
pumps with no moving parts (except the
impeller), made
of bronze, and engineered specifically for PV operation.
It requires only
20 watts of solar power when used anywhere north
of Florida.
(10 watts in the southern climes).
We have been overrun
with hundreds of ladybugs in the
last few days.
They swarm around the doors and windows,
as bugs go they
are pretty benign - and cute!
