Geothermal Heating And Cooling

What are the benefits of geothermal heating and cooling?

Geothermal heat pumps for heating and cooling residences as wellas commercials spaces have host of benefits over othertypes of heating andcooling means.These heat pumps basically use heat of the earth ornatural water bodies to cool or heat rooms. Let’s take look at their benefits.

Operation Cost in minimum: Gas furnaces are randomly used today in homes as wellas commercial areas. They are called highly efficient and their efficiency rate can reach up to 94%. Butthese not even fitto holda candle to their geothermal counterparts whose energyefficiency reaches 400%. Just imagine you will be delivered with 4 units of energy for consumption of every 1 unit of electrical energy!This is because geothermal heatpumps work by transferring heat and donot need to burn any fuel to generate heat. Itssource of heat is the ground which is absolutely renewable and free. It can reduce you electrical bills by 70%, if you convert to it from electrical, oil or propane furnaces.

Noiseless Operation:
Remember those days when you are enjoying a picnic or barbeque party on the lawn and noise from the outdoor unit of your air conditioner and heat pump constantly interrupts with revelry. The geothermal heating and cooling system does not have any outdoor unit. So there is no chance of any noise being createdby these units outdoors. They arelesslikely to undergo wear and tear due to inclement weather conditions or vandalism.

Eco-friendly: We live in a time when governments around the world are thrusting on usage of cleaner energy sources that will reduce carbon footprint. This will also save the non-renewable resources suchas the fossilfuels. The price of fossil fuels will rise even more in days to come. Geothermal heat pumps meet both thesecriteria quite aptly. These heat pumpshave been recognized by the EPA and the U.S. Department of Energy as the most environmentally friendly way to heat and cool homes. It does not release greenhouse gases such ascarbon dioxide, carbon monoxide which contribute to air quality pollution. It will also reduce dependence on electric grids. A single geothermal heating and cooling unit can cut down emission that amounts to planting an acre of trees or taking out two cars from the roads.

Longevity: The geothermal pumps have longer lifespan. Ona average a geothermal heat pump can last up to 15+ years. A life span of typicalfurnace is 7-10 years with regular maintenance. Infact, the ground loop of a geothermal pump from where it absorbs the heart of the earth has a warranty of 50 years. These loops are made of polypropylene pipe which is used to make gas lines.

Comfort: It is another big advantage of geothermal heatpumps. It helps you to maintain a comfortable ambienttemperature. The temperature below the earth is always cooler than the surface air in hot weather and warmer than the surface air in cold climates. As a result the free and rich heat source is constantlyproducingheatwithout bursting fuels to meet the needs of the thermostat.

Independence: There are areas where electricalsupply is not widespread. Such areas always have huge power deficits and cannot cope up with the power demands. In such places these ground source heat pumps are ideal for heating and cooling. You become more or less self-reliant in meeting your cooling and heating needs. This is because you are tapping a resource that you own. It willgive you riddance from the hassle of calling orwaiting for oil delivery truck. And the operational process of geothermal heat pump will never rise.

The onlyflip side of geothermal heat pump is itsinstallation cost. It can costapproximately $10,000 to $30,000. However, the price will depend on a wide range of factors like soil conditions, available area and its accessibility, system design, the amount of digging and drilling required. A 2,000-sq.-ft. home would need a geothermal unit ranging from $10,000 to $20,000. To install a system your existing duct work will also need amodification. In some areas extensive excavation is required. This isgenerally true for older homes where the whole heating and cooling design will have to undergo a change to accommodate ground source heat pumps. For newer homes the cost can be 40% less. But you are likely to recoup the buying and installation cost with energy savings.
