A tankless hot water heater is an efficient way to heat water, they are fitted with an electric, gas, or propane-heating device. These heaters are compact in size and virtually eliminates costly standby losses, they can provide warm water at remote points of use and less water is wasted while waiting for warm water to reach a remote faucet. Tankless heaters are compact in size and virtually eliminate the wasted energy of heating a large volume of water.

The tankless hot water heater is available at the homeowner’s request, in other words, the heated water is available on call with no limitations as to the quantity you can use. For the environmentally conscious, they use far less energy and natural gas then traditional hot water heaters. Home owners can see a typical savings of up to 50 – 60 percent on their gas bill after a tankless water heater is installed. A tankless water heater is more affordable than before ($500) and significantly reduces your water heating bill.

The tankless hot water heater is gaining in popularity as more people realize that they can save them money over the long run. Unlike a typical storage tank type hot water heater, tankless water heaters do not work by maintaining a tank of water at a consistent, high temperature. They are more efficient than traditional gas or electric heaters, and can cut your related energy costs by up to 50%. And this applies to Gas Tank style hot water heaters as well.

Demand water heaters are available in propane, natural gas, or electric models. They come in a variety of sizes for different applications, such as a whole-house water heater, a hot water source for a remote bathroom or hot tub, or as a boiler to provide hot water for a home heating system. Demand water heaters do cost more than conventional storage tank-type units. The appeal of demand water heaters is not only the elimination of the tank standby losses and the resulting lower operating costs, but also the fact that the heater delivers hot water continuously.

Storage tank heaters last 10 to 15 years but most tankless models have easily replaceable parts that can extend their life by many years more. Storage-type hot water heaters lose heat all day long consuming more energy than any other job in the home except space heating.

Tankless hot water heater systems only use energy to heat water when there is a demand for it, providing instantaneous hot water whereas conventional tank systems use energy to keep the water in the storage tank hot so that it is available when needed. These hot water heaters (also called “demand” or “instantaneous”) are far more energy efficient because they heat water only when you need it.
