Recycled plastic bottle solar water heater is an effective and zero fuel consumption way to heat the water for domestic purposes. It can be made by following easy steps and using simple recycle material and can fulfill the need of an average house.

Material required for making of Recycled Plastic Bottle Solar Water Heater

  1. 1.5 liter transparent soft drink bottles
  2. Wood for making of frame
  3. Aluminum pipe
  4. Rubber Gas pipe
  5. Black paint
  6. Handsaw and Hacksaw
  7. Electrical tape

Working

Transparent bottles create green house effect and heat the water flowing in the pipes. The flow rate of water must be adjusted according to the required temperature at the outlet.  The flow rate is  0.33 liter/min to raise the temperature of water from 20 Degree Celsius to 60 degree Celsius. The working of the heater depends upon the atmospheric temperature and duration of solar radiation. The optimum output is between 11am to 2pm and the average is 160 liter per day with the average temperature of 45 degree Celsius.

  • thanks,
    i have some questions.
    how much time it is required to get hot water?
    Will it work as instant water heater?
    Can you make video of the complete project instead of pictures?
    I have understood the frame but can you please show it with the storage tank and till we get the hot water.
