Choosing a High Efficiency Water Heater
The
tankless water heater is one such appliance that helps you save money and keeps
your house eco-friendly. What sets apart the tankless heater from conventional
water heaters? Obviously the "tankless" description implies the
greatest differentiation, but in most cases the tankless model heats water
quickly and more efficiently. Some tankless heaters may also come smaller than
conventional models, which can save you some space in the utility room. The demand water heater - with this model
the water heats instantly without the need for a tank.
The
tankless coil heater - similar to the above appliance, but your home's space
heating system warms the water. If you want to truly rely upon green resources
for your water heating, there are also solar-powered heaters on the market. You
may wish to have a professional plumbing mechanic assess your home to see if a
solar heater is your best option before you buy, however.
As
you shop for options, take note to consider the following qualifications of a
quality, high efficiency water heater. High Efficiency Water Heaters Water
heating represents about 11% of residential energy costs. Amazingly, you can
achieve a 10% reduction in water heating costs when you turn down your water
heater from 140 degrees to 120 degrees. This will not produce a noticeable
difference to your hot water usage. Typically, households are use to hot water
systems that are called "stand-by systems" -- made up of perpetually
hot water tanks, that distribute hot water as and when required. Since this
water has to stay hot, some heat will dissipated through the surrounding air. Modern
heaters with their effective insulation have made this practice obsolete.

High-efficiency
water heaters
make use of highly insulative foam such as R-19 to reduce this loss, by
positioning the form between the tank and the outer surface of water heaters. This
"EnergyGuide" has to indicate the electricity costs for that
particular high efficient heater, derived from average cost of electricity in
the United States.
It
used to be common practice to wrap around water heat tanks with blankets to
provide the external insulation. These old water heaters did not have
sufficient internal insulation, thus making the external insulation necessary
to achieve reduction in "standby losses" and subsequently the
operating costs.
Now
high-efficiency water heaters
come with built-in and high quality insulation, thus making the concept of
external insulation blanket unnecessary. Water heaters that are manufactured in
the last 10 years belong to this highly efficient category. The standby concept
in the old system heats the water all the times.
