Geothermal Residential Heating
South Australia, Queensland, New South Wales,
Geothermal residential heating and
cooling is one of the most popular options for people who want to make their
home more environmentally friendly. Some of the facts about these systems
make them a rather significant choice, however, for homeowners who are
considering upgrading to this type of HVAC. You'll have to take into account
the cost of the system and the suitability of the system for your area before
proceeding, which is something they need to consult with an expert
Generally, the most
expensive part of geothermal residential heating systems is the ground loop that
needs to be installed to provide the heating and cooling exchange with the Earth.
This loop can sometimes be open, in which cases the geothermal energy heating pump
draws water from the water table, circulates it through the home and then deposits
it back into the Earth. They also might be a closed loop that uses another medium,
generally a type of anti-freeze, to provide the heat exchange action. The latter
arrangement is more common for geothermal residential heating and cooling. While
there are some significant advantages to open loop systems, they also come with the
potentially variable water table to consider.
Advantages and Disadvantages of Geothermal Heatpumps in
Geothermal energy is a method of using the pre-existing heat of the earth to
heat a home, and it is also a method of using the earth to cool a home too. A
geothermal system relies on specialized equipment that includes a closed loop of
pipes buried vertically or horizontally into the ground, a heating pump, and even a
desuperheater that is capable of creating domestic hot water supplies.
To simplify things, it is useful to think of geothermal heat as a method totally
different than any other type of heating or cooling because it does not rely on any
fossil fuels to generate heat or provide cooling. When it does use electricity it
is simply to operate the pump or fan that distributes the air throughout the home
or living space.
What are the advantages of
using a geothermal system? There are many, and they include:
Financial Savings – Not only does the owner of a GHP (geothermal
heating pump) get to enjoy reduced costs on things like home fuel
oil, but they also reduce general operating costs by around 80%.
This is because the systems demand far less energy IN GENERAL
thanks to their efficiency and their use of the earth instead of
the air for the creation of heat;
Friendly – Clearly, it is a huge advantage to
use a system of renewable energy to heat and cool your home, and to
also create domestic hot water supplies. Because there is no need
to burn up a fuel in order to create heat, a GHP system is going to
be almost pollution free (with the exception of the electrical
supplies used to power the pump).
How Much Does Geothermal Cost?
For geothermal, the cost of installation is higher than it would be with other
forms of energy. The exact figure, however, is something that you’ll have to
consult with a professional with to find out. Some systems can be very expensive
and others can be surprisingly affordable. There will be some differences depending
upon where you live, how much of an underground loop you have to run and so forth.
Of course, if you’re simply adding a new pump or other hardware to an existing
loop, the costs will be considerably
