https://sites.google.com/site/solarsu… I was in need of a cheap way of reducing my electric bill In 1972 We were behind over a $1000 dollars on their electric bill because they lived in an (All-Electric Home) and his electric bill was $240 dollars per month. He had to find a way to reduce his bill or, lose his home. I made my first (Batch type) solar water heater in 1972. I made my first (Thermo-siphon type) solar water heater system in 1973 1: Do not mix metals, the deterioration of different types metals can be accelerated by allowing them come in contact with other types of metals. 2: One problem with a thermo-siphon system is that the collectors can get hot enough to blow a temperature relief valve. 3: The tilt angle has a major impact on the solar radiation incident on a surface. The winter tilt angle of 65˚ degree will drop the summer and rise the winter to about 145˚f to 160˚f of equal temperature. You can stop it from Blowing it’s Stack with the winter tilt angle of 65˚ degree. 4: Thermo-siphon can only transfer heat “upward”. Orientation is much more important for thermo-siphon. Also, thermo-siphon can fail because of a bubble in the loop, and require a circulating loop of pipes. 5: No bents in the flow-tubes, for water to pool. 6: The thermo-siphon system will not work, if the flow-tubes don’t have a upward flow all of the way too the storage tank and a down ward flow from the storage tank, with no bends in the tubing for water to pool. The most difficult part of learning how to solder would be.
What works for me is to first clean the pipe end and the inside of the fitting with a combination of wire brush, fine sandpaper then apply flux. Insert the pipe end into the fitting. Heat the pipe and fitting until solder touched to the side opposite the heat source melts and it will instantly fill the entire void between the pipe and fitting. Allow to cool until solid and then use a damp rag to wipe the joints.
The new 4′ feet x 8′ feet flow tubes made in 2013 this year.
Open loop systems are the simplest to design and construct. The size here in north Alabama of about 30 sq. ft. of solar panel with sheet metal heat absorbing fins and 80 gal. water storage tank, mounted at least two feet or more above collector flow-tubes. My personal view is that the single, serpentine path is likely to perform more consistently it gets the water up to a usable tank temperature better than the parallel type of connection. My existing solar hot water heater has performed flawlessly for forty years so I will stick with a proven design. It’s simple and easy to construct, no hassle to maintain. A thermo-siphon system requires neither pump nor controller. The system rely on the principle that hot water rises, and cooler water sinks. Adding absorbing fins to the collector flow-tubes, helps collect more heat to the flow-tubes. As the sun heats the water in the collector during the daylight hours, it will rise to the tank above it. The solar heated water flows from the tank when ever hot water is used within your home. Water can freeze in a panel on a clear night with temperature below 32˚f. Dad has some more tolerance in his system as his panel is located in his sun space. So freezing water in his pipes will not happen until maybe 20-25˚f (roughly). He drains about 1 to 2 gallons of water out the flow-tubes. Heat Exchangers do lose about 30 to 50 percent of the heat. Here’s What A Do it Yourself Thermo-siphon Solar Water System will do for you It’s, the best investment you can ever make. We have 4 at home Faith and Me, Dad and Mom. Now Me and Faith take a bath every day I, will stay in the shower for over 30 minutes then, Faith will do the same, all between 6:30 p.m. and 8:00 p.m. Dad will take a bath or shower at 8:00 a.m. to 9:00 a.m. and my Mom maybe at 10:00 am and every day at least two full washer of clothes. We all have hot water and the dish washer gets used at least four times a day.
