Water Heaters Energy Efficient is needed for most
of household. Consumers have a tendency to purchase their heater based on size.
You may find yourself buying what ever is available, instead of what is best! Actually
the First Hour Rating (FHR) is more important to consider. The FHR represents
the amount of hot water that the unit will deliver during a busy hour. There is
a wider selection of water heaters for consumers to choose from.
Advances in technology
have developed the environment friendly tankless water heater, but even the
traditional tank heaters now have energy efficient models. Since it is estimated
that up to 30% of a regular household's energy budget is used on heating water,
it is easy to realize that shifting to an eco-friendly model will pay for
itself in the long run.
The most energy efficient water
heaters are generally gas fired. Electric resistance is an expensive way to generate
heat and not as environmentally friendly. Before you make the final decision, check
with your utility company to see if they have any incentives that may make electricity
more attractive.
When you have a limited budget or
when the household have several places that have to be supplied with hot water
at the same time, a storage tank water heater ins your ideal choice. The tank capacity
must be based on how many gallons your household needs during the peak hours of
use. You must also look at the energy factor (EF) and avoid buying based on cost
and size. A higher EF rating means better energy efficiency and better insulation
on the tank which is also important.
The next type is a heat pump water
heater or desuperheater. With this type the electric is used to move the heat from
one place to another instead of actually creating it. The heat source comes from
the heat in the outside air or the area where the unit is located. This type is
not very common and harder to find.
Solar water heaters use the sun
to heat your water. They are very expensive and hard to calculate the cost because
there are so many factors that affect it. These would include the amount of sun,
where you live, which way your roof is facing and the amount of hot water that
you use. If everything is right though they offer a virtually cost free hot water
from a renewable energy. Seems like solar power was hot, then cold and now it seems
to be making a comeback. There seem to be many opinions out there for and against
solar power. The drawback is that you must have some type of backup system for when
there is no sun.
