Benefits & Considerations Efficiency: Heat pump water heaters perform up to 3 times more efficiently than standard water heating systems. Safer: Heat pumps don''t require burning fossil fuels or fuel storage, eliminating the potential release of carbon monoxide. Longevity: These systems last longer than standard systems and cost half as much to operate.
When you add a solar cell to the water tower / turbine / pump scheme, what you essentially have is a solar power system employing a water tower as an energy storage device. Such a system could store collected solar energy by pumping water up into the tower, and when the sun isn''t shining, the system can still produce power from the turbine.
