SOLAR HOT WATER 2 DIY USING BLACK WATER HOSE SOLAR WATER HEATER SUN POWER

Part 2 of a 2 part series showing how to install a cheap cost effective solar hot water heater. http://greenpowerscience.com/

This is the concept. Anything black or very dark colored ab- sorbs solar radiation or heat energy. Any- thing light colored or mirrored/shiny re-
flects the heat back up into the atmosphere. This process involves placing several feet of black hose in the sun and circulating a liquid inside the tubes to leach the heat out. This heat is then released inside a water tank for heating water or radiator system to warm your home.
HOM MUCH ENERGY?
It is estimated that the sun produces 1000 joules of heat energy per square meter (about 3.3 feet by 3.3 feet). 1 Joule equals 1 Watt. So 1.5 square me- ters (the size of a small kitchen table) equals 1500 watts or one hair dryer. It is not possible to retain 100% of the solar energy. This is where the word efficiency comes into play. While black objects absorb much of the sunlight’s heat, some is lost due to reflection, atmospheric leaching and wind. Realistically we will be capturing about 60% of the solar heat.

    After 10 years the poly tubbing holding up strong and the only issues have been the connector that popped loose from moving the thick heave tubing. Works great and saves about $20 a moth on average. That is $4,000 over the years for one days labor and free materials or $200 retail for the tubing.

  2. interesting … except for the fact that your car cover was very shaky … even Florida gets 'windy' weather. dont know if your shed will stay up or even in your yard.

  3. Nice, my father did this for our in-ground pool in the 70's with 2 inch tubing on the bungalow and house roof. He moved a lot to the house roof coz it was tiled and stronger than the tin roof as there was a LOT of water up there! It was also turned off with an in-line tap in summer coz the water got too hot in the pool and even in winter it kept the pool a nice temp…. 🙂 Guess he's just a smart guy!

  4. A large salt company had pools of salt water on a salt river and had the water dyed a dark green. I questioned why they had chosen that color to evaporate the water and was told their studies found the green water dissipated faster than black. Green gets hotter they said. I only logged in to comment to help improve the design. Peace.

  5. I like the idea. However, having lived in FL for years, I can tell you that car port is going to be very unstable in a bad storm and a total loss in a hurricane. I saw a shed or small pole barn near the house, why not use that? Or even better yet, the roof of the house? Or an old satellite dish?

  6. Any info. is  helpful, but  this  could use some detail ~  and  less of the brainless chit-chat.
    eg. Do do you get ~ and maintain a  thermo-syphon within  the  COILED pipe.
