Recycled Pet Bottle Solar water heater
Recycled Plastic Bottle Solar Water Heater DIY Project
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.
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.

how much time it is required to get hot water?
Will it work as instant water heater?
