This is a terribly inefficient (and therefore environmentally harmful) way to make hot water, but the good news is you can save hundreds of gallons of oil per year by switching to a solar powered water heater, and powering it with solar.

How unpressurized solar water heater works
1. Unpressurized solar water heater of all glass evacuated tube collector integrated with storage tank, are ideal for use in houses and other applications where cheap, reliable hot water supply is required. They are simple, economic and practical.
2. As the specific gravities of hot water and cold water are different, cold water goes downward and hot water goes upward.
3. When cold water in evacuated tubes is heated, it becomes lighter and goes to the water tank, while cold water in the tank goes down to the evacuated tubes
4. Through this circulation, the cold water in the water tank will be gradually heated.
