Tankless-water-heaters have been popular in Europe and Asia for many, many years,

but in United States have become popular only recently.

What is a tankless water heater?

It is also call is “on demand” water-heater -increased energy efficiency 10% – 50 % .A tankless unit provide hot water only as it is needed This results in energy savings of from 14% to 50% depending on the size.

The traditional storage tank  heaters keep
large quantities of water heated whether or not  is about to get used. Storage tank  heaters also reheat water that has not been used but has cooled inside the tank. On the other hand, a tankless  heaters only expends energy to heat water as it is used. The energy savings from using a tankless water heater instead of a storage tank unit are approximately 20% of your energy bill that goes to heating water.

Types of tankless gas heaters

Tankless water heaters are physically smaller than conventional tank heaters and are generally wall mounted.There are two types of tankless-water-heaters:

- Point of use – water-heaters are designed for dedicated use, meaning they supply a single faucet,

shower or appliance. “Point of use” tankless-water heaters are smaller than whole house models and fit easily

in a bathroom vanity cabinet or linen closet.
- Whole house tankless-water-heaters will heat water for all needs throughout the house. These water heaters are larger than “point of use” heaters and are best situated in basements, garages or, depending on the climate where you live, outside.

Tankless-heaters can be fueled by gas (natural or propane) or electricity.

Your fuel choice will affect the heater’s price, cost to operate and flow rate.

Gas  heaters are generally larger than electric units and cost more initially, but since gas
is cheaper than electricity, gas powered tankless heaters are less expensive to operate. They can also generate larger flow rates, making them a more effective whole-house choice. If you’re considering a gas-powered tankless-water-heater choose a model without a pilot light to save energy and reduce operating costs.

Electric heaters are less expensive up front but cost more to operate. They also have lower flow rates than gas-powered units, so they’re better suited for point-of-use needs unless your home’s required flow rate doesn’t exceed its power. To maximize energy savings, look for tankless units with modulating controls that increase or decrease the amount of energy required to heat the-water depending on the flow rate.

Many tankless heaters qualify for the $300 Federal tax credit, so will get a well deserved break in that direction. Tankless-water-heater will last up to 20 years twice as long as conventional tank heaters. Add in their energy efficiency and lower operating costs . In most cases , the savings are even more if the  heating unit is installed outside.While a tankless-gas-water-heater is quite an investment, it will pay for itself over time. The best part is that once it has paid for the investment, you willkeep saving money each month..
