hi i want to heat a tank of water in the summer. the tank will be outside. i was thinking of painting it black for the sun to heat or put a heater in the tank. i want the water to still be warm in the night if it cools down. Can you give me some ideas to heat a tank of water. i want to use the rain water for an to fill the tank.

Get a bunch of pipe and build something like a radiator, paint the pipe black and lay it in the full sun. Pump the water through it in a closed circuit with the pool.

Paint your tank black and leave it in the sun. Surround it with reflectors to direct sunlight onto it so as to increase the amount of sunlight the tank collects.

Then lay your big tank out in the sun and try to block stray breezes.

Well I can suggest you to provide outlet at upper side of tank to take out water as hot water has low density and will be available at upper outlet. Also arrange some feeder arrangement so that it will fill automatically. You can save this hot water in thermostat which will maintain its temp. for long time. I suggest you to use thermocol for that.

How big is your tank? What is the volume of water in the tank?

Buy a solar shower and lay it on the sunny side of the roof.

Or, you could just put a black plastic barrel on the sunny side of the building and let rainwater run into it. Then make a blanket cover out of closed cell foam (or buy a "water heater blanket") and cover the barrel at night.

If the house is tall enough, build a stand for the barrel (remember water weighs about eight pounds per gallon) which will let rainwater from the gutter system run in, but will let you use the barrel as a gravity shower.
