The cheapest solar boiler

Step 2 Modifications and Operation

Modifying water connections
basically what we have to do is connect directly to the departure of water tank shower and black paint of the water tank, that is to better absorb heat from sunlight

mode of operation
all you have to do is close the valve “B” step in that do not reach the normal supply of water to the shower, so only use water from the water tank.
the valve “B” must be open when no one was to bathe for refill the water tank.
