hot water storage. - Page 2

Back up for when there is no sunshine next winter. It will help heat water and air for the house. Plan to run a 3" - 4" pvc line to the basement of the house from the shed.

For right now this barrel stove gets hot setting in the sun. No, wood needed. Might use it as a collector to heat water, till fall.

I plan to use the Swiftech pump for the barrel stove. The Delavan I bought at rural king. It's a 12 volt pump used to spray herbicide and such from a farm tractor. It should be able to pump water to the roof solar collectors I'm building.

Spent the day putting all the panels in one place.

This well be the power supply for the solar heated water. 270 watts 22.5 amps if the Sun is good. Hope to add 90 more watts for total of 30 amps which well max out my charger. I'm hopeful this well be enough to run the pumps and fans needed to heat the house during the winter and all hot water year round. Have a lot of work to go yet.

Working on two more panels to put on the roof.

Ran low on flashing. Pricey stuff. I have some old gutter I might try to strip over the pipe. Won't be pretty but the sun don't care.

I Read somewhere, someone used thin roof tar to paint their solar panel. I would think tar would transfer heat fairly well. Be lot cheaper than flashing.

The one thing I dread is getting the panels on the roof to heavy in one piece. I'll need to build them, than disassemble and than put them back together on the roof.

Also been wondering if I should run separate water to each panel or run the water through one panel than the other one.

I plan to have four total panels on the roof. My nephew Says to put a solenoid valve on each with a bi metal thermostat. I have early morning shadow over part of the roof.

Normally, the water should pass through each panel. Even on low sun days,
the water picks up more heat with each panel.

At least that's the way my 3 panel system was set up.
I pumped the water up into the bottom of the #1 panel, and out the top of the #3 panel.

If a shadow is cast on one of your panels in the middle of the loop, that should not have
much effect on a well insulated collector. Just a little heat loss, until the sun comes around.

Due to the side angle of early morning sun, a South facing collector does not
pick up a large amount of energy early in the morning.

Long shadows early in the morning and late in the afternoon are factors
that you just have to put up with, in many installations.

I have tree blockage before 10:30 AM and after 5:30 PM
on my backyard tracking mount. But when it sees the sun,
I get really good energy!
