Geothermal Heat Pump Systems use the Constant Temperature of the Ground
Geothermal Heating and Cooling is often referred to as Geoexchange, Geothermal, or Ground Source Heating and Cooling. Geothermal heating & cooling is not to be confused with a geothermal power plant. A geothermal power plant generates electricity using the core of the earth. We are talking about using the crust of the earth to heat and cool a home or building.
Ground temperatures are a constant 55° all year no matter what the weather’s like outside.
Geothermal works because the ground beneath our feet is warmer then the outside air in the winter and cooler in the summer. Inserting a series of small pipes into the ground allows heat to be transferred to and from your home. In this process heat is not created, it is transported thereby eliminating the need to burn fuel.
Yes, Geothermal Systems are possible in your neighborhood! In fact geothermal systems are used in almost every state in the USA. Ideal candidates are homeowners who currently burn expensive heating oil or propane.
Two Pieces to the Geothermal System
Winter Operation: The underground pipes, called a ground loop, circulate water which absorbs the heat from the earth and returns it to the indoor heat pump. The heat pump extracts the heat from the liquid then distributes it throughout your home as warm air. With the heat removed, the water is re-circulated to collect more heat from the ground. This cycle keeps your home warm (and can even pre-heat your home’s water supply) while vastly reducing the need for fuel or other costly non-renewable resources.
Summer Operation: The indoor heat pump takes the hot air from your home and extracts the heat. This leaves behind cool air to be distributed throughout your home’s vents as air-conditioning. The removed heat from the air is absorbed by the water in the ground loops and then rejected into the cool earth. In this case, the water is warmer leaving the home then when it returns.

Heat Pump – the unit inside the house that moves the heated or cooled air.
2.
Ground Loop – the underground pipes that transfer the hot or cold energy that connect to the heat pump.
This is not a new technology – nor is it a science experiment. The EPA has acknowledged geothermal systems as the most energy efficient, environmentally clean, and cost-effective space conditioning systems available on the market. Geothermal heating and cooling is also the standard in many European nations. In Sweden and Switzerland for instance, more than 75% of new homes have geothermal. If you currently spend too much on electricity, oil, or propane to heat your home, then it is a good idea to explore what switching to geothermal can mean for your bottom line.
...and is most attractive in the following situations
Now is a great time to switch to geothermal – a 30% Federal Tax Credit is available on the cost of the entire installation – not to mention the premium comfort of the most efficient heating and cooling system on earth.
Geothermal Tax Credit Information – Federal, State, & Local
There are many Federal, State, and Local incentives and loans for installing geothermal. The largest incentive is the Federal 30% Tax Credit on the entire geothermal system. For a complete list of local incentives click on your state.
Geothermal System Installation Example
Here is a step by step process for an instillation project in Pennsylvania
step 1
Allied performs a site check prior to all geothermal jobs to address any and all concerns a customer might have. Here, protection of the brick patio was a major concern for us and the customer
step 2
Allied handles all phases of the permitting process – from application to pick-up
step 3
Reinforced mats are placed in an overlapping fashion to help distribute the weight of the drill rig, reducing the risk of cracking or settling the pavers. Borehole location is white flag in foreground
step 4
Rig backed onto mats to access borehole
step 5
Mats have also helped to catch mud and keep the yard mess to a minimum. Note silt fence in background, keeping mud from running free
step 6
After loops are installed and rig is pulled out of driveway, crew hoses and scrubs down the driveway
step 7
Very thorough cleaning!
step 8
Note rig off the property, clean condition of driveway, and not a single paver cracked or sunken
step 9
Beginning of horizontal pipe trenching, and mobilization of mini excavator, also calls for reinforced mat placement
step 10
Crew in trench performing heat fusion of HDPE pipe
step 11
Completed reverse-return 2-loop header before back-fill
step 12
Supply and return lines stubbed into house foundation wall and sealed
step 13
Plumb and insulated interior lines running to multiple circulating pumps
step 14
Hose kit lines plumbed with ball and check valves from circulating pump to geothermal unit
step 15
Beginning yard restoration after a rough grade with mini excavator and hand rake by the crew
step 16
Finished yard restoration with straw laid for erosion protection and to facilitate seed growth, and no changes to existing grade conditions
step 17
After a couple months, your yard will look just as it had before the drilling!
