When more people know they can save them money in the long run, the tankless hot water heater is gaining popularity. Unlike a conventional hot water heater style storage tank, tankless water heaters don’t operate by holding a water tank at a constant, high temperature.

Water heaters with demand are available in propane, natural gas, or electric versions. They come in a range of sizes for various applications, such as a whole-house water heater, a source of hot water for a remote bathroom or hot tub, or as a boiler to provide hot water for a home heating system.

The benefit of demand water heaters is not just the reduction of standby tank losses and the resulting lower running costs but also the fact that the heater constantly provides hot water.
