What is A Geothermal Heat Pump?

A geothermal heat pump or a geothermal system may also be called a "ground-source heat pump". These geothermal systems work in a relatively simple fashion: The ground below the frost line (usually between 4 and 5 feet) typically has a constant temperature of approximately 50 degrees year round.

The geothermal system takes heat from the earth and the heat is transferred to the air in your unit during winter time and the exact same process is reversed during the summer months.

Piping in loops is buried below the earth's surface either horizontally or vertically. The ground loop of piping is attached to a pumping module inside the facility where a mix of water and liquid antifreeze is then circulated throughout the system.

When the liquid mix then moves through the pipe loops during the cold months, the geothermal system will absorb the heat from the ground. Once the heated liquids reach the heat exchanger they are converted through the refrigerant process and converted to warm air that then can be circulated throughout the facility.

Your system during the summer months or warmer time of year reverses the process with a simple flip of the systems switch.

Significant energy savings

Geothermal systems are great for the environment because they can save on heating bills up to 50% and can save up to 30% on air conditioning bills. Keep in mind that heat from the ground is "free", and the only need for electricity is for the circulation of the heat or cool air throughout the building. Utilizing these types of systems in Washington, DC Montgomery County, Prince Georges County Maryland and in general the mid-Atlantic region is wise because of the protections to the environment and of course the financial savings.

Changing over from conventional systems could allow you to reap a full return on your investment in as little as 2-7 years. Your trained technician from Harvey Hottel can provide you with a better estimate on potential payback.

Should you wish to go one step further for additional energy savings, you can add an attachment to your geothermal unit called a "desuperheater" that will connect your geothermal heat pump to you water heater. When the energy from the geothermal heat pump isn't utilized, the geothermal system will divert it to your water heater so will you will be drastically reducing the cost of gas or electricity to heat your home or buildings water.
