One of the most energy efficient water heating methods is the heat pump water heater. This method is proven to be two times more efficient over the standard electric water heater.

Tankless. A tankless heater heats the water as you use it. It doesn't store hot water and keep it hot day and night whether any is used or not. The water is heated almost instantaneously, and the heater will keep the hot water flowing as long as the water is turned on.

A large energy saving one. It will keep lots of hot water and will use less energy when not in use.

There is no single answer to this question. Water heaters with Energy Star certification are your best bet. However, the important considerations are what you need. If you get the right size, set the right temperature, and insulate your water heater, that will make more difference than the specific brand. The most energy efficient hot water heaters are tankless. Check your local Home Depot or Lowes for pricing and installation information.

Water is a pretty exclusive liquid. Boiling it will leave behind almost anything that's mixed in. After boiling all the water, there will be all the dried salt residues and probably several other substances, too. Distillation is the most efficient way to get pure water.

The Fahrenheat Electric 5120 BTU Baseboard Heater is very energy efficient. Because of its "baseboard" design, it is not necessary to use a powerful to disperse the heat. It uses natural radiance, which saves on electricity costs.

The difference between a mobile gas water heater and a standard gas water heater is that a MH unit will use an outside air intake for combustion. That is the most important difference.
