Introduction: Homemade Solar Water Heater Forced Circulation With Mini Pump
This is a project on a homemade solar water heater.
There is not a project for entertaining, has three years of use on my roof for 4 people shower and dishwasher.
260Liters water is in summer about 60-70ºC
260Liters water is in winter about 30-40ºC, my system able for reduce capacity and work with less liters.
Combination of elements planned than i used give me a result really surprising.
My system has the following advantages.
- My water bottle:
Its of plastic for food, is hot water resistant.
As plastic does not rust and does not produce lime.
Pressure is open, has a small vent tube that releases any pressure to the drum with reduce temperature, filling a floating buoy to fill with open pressure, and water fisherman pipe to collect hotter upper level.
Very good insulated with aluminum paper, polystyrene, polyurethane and cardboard.
This system is great because commercial systems always mixed with cold water while the hot water is consumed.
My system allows me close cold water on cloudy days, and botle gives me all the hot water without mixtures.
- Screen plates:
The plates are copper tubes, aluminum foil absorber domestic economic and readily available, insulate with polystyrene, polyurethane and aluminum paper,
The display with double layer polycarbonate. (not glass, glass is not good insulator of heat and is delicate to handle and easy to break)
- Circulation system:
A circulation system easy to install and very smart to get to the last degree heat.
This sistems is one differencial thermal electronic, a hot water pump brushless.
