Tankless Water Heaters Resources
Tankless Gas Water Heaters - more energy efficient
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..
