Don’t sacrifice your health by not getting air filters for your home. Air filters are essential in our homes because they prevent unwanted particles to get in contact with us that may cause us harm.

How does a geothermal heat pump work?
ge·o·ther·mal: of or using the heat of the earth’s interior
Above the ground we can expect to experience dramatic temperature changes throughout the year. However, just a few feet below the Earth’s surface the temperature remains more constant at around 50 to 60°F. A geothermal heat pump takes advantage of these more mild temperatures through a series of pipes and a heat exchanger.

In winter, when ground temperatures hover around 50° F, these systems pump fluid underground through a series of buried pipes, called a loop. The fluid becomes naturally heated, circulates back into the home, and an electrically driven compressor and heat exchanger concentrate the Earth’s energy and releases it inside the home at a higher temperature.

In summer, the process is reversed. The underground loop draws excess heat from the house and allows it to be absorbed by the Earth. The system cools your home in the same way that a refrigerator keeps your food cool – by drawing heat from the interior, not by blowing in cold air.

As with any heat pump, geothermal and water-source heat pumps are able to heat, cool, and, if so equipped, supply the house with hot water. Some models of geothermal systems are available with two-speed compressors and variable fans for more comfort and energy savings. They are smaller than a traditional heating/cooling unit and can easily be retrofitted into any home.

Did you know the earth can heat and cool your home while saving on energy costs over the long term?

Just below the earth’s surface, the temperature remains relatively constant throughout the year by absorbing half the sun’s energy. Geothermal heat pumps tap into this natural ground source of energy reducing heating costs up to 60%, and cooling costs by 25% in summer months. GHP’s have three components: a ground heat pump, a closed pipe system, and the air delivery system. Buried in the ground is the closed loop, which is a continuous loop of polyethylene pipe. It’s filled with water or an anti-freeze solution and connected to an indoor heat pump, forming an underground loop. The system circulates water through underground pipes that ultimately carry water through the home’s air transfer unit. In the heating mode, the liquid in the pipes is cooler than the ground. In the cooling mode, the soil is cooler than the liquid.

Geothermal technology has been around for a while, but is gradually becoming more popular. A geothermal system costs about twice as much as a conventional heating and cooling system; however, the energy savings combined with the new tax credit on these systems, most people make their investment back in three to five years. In Florida, that could mean a savings of up to $40 a month on air conditioning bills.

These systems are extremely durable, and when properly installed, this tubing will last fifty years or longer.
