Gas water heaters are an economical solution. A gas water heater will also help save space in your home. Some of the advantages of gas systems include water supplied at higher flow rates, reliable service for 10 years or more, great energy savings, and low operating costs.
Electric water heaters also have their advantages. While gas systems can be limited to certain areas of a home or building, electric water heaters can be installed most anywhere. Electric water heaters generally require less parts.

Demand (tankless or instantaneous) water heaters have heating devices that are activated by the flow of water, so they provide hot water only as needed and without the use of a storage tank. They don't produce the standby energy losses associated with storage water heaters.
How Tankless Water Heaters Work
Tankless Water Heaters or demand water heaters heat water directly without the use of a storage tank. Therefore, they avoid the standby heat losses associated with storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, demand water heaters deliver a constant supply of hot water. However, a demand water heater's output limits the flow rate.
Typically, demand water heaters provide hot water at a rate of 2–5 gallons (7.6–15.2 liters) per minute, and gas-fired models have a higher hot water output than electric models. They come in a variety of sizes for different applications, such as a whole building water heater, a hot water source for a remote bathroom or hot tub, or as a boiler to provide hot water for a heating system. Demand water heaters can also be used as a booster for dishwashers, washing machines, and a solar or wood-fired hot water system.
Demand water heaters may be installed centrally or at the point of use, depending on the amount of hot water required. The largest gas units, which may provide all the hot water needs of a small commercial building, are installed centrally, while a small electric unit acting a as a booster for a remote bathroom or laundry may be installed in a closet or under a sink.
