Geothermal Heat Pump systems are one newest, most efficient forms of heating in today’s market. Although more expensive to buy and have installed, the system will more than pay for itself in the long run, saving a substantial amount in heating and cooling costs annually.
What is a Geothermal Heat Pump?
Geothermal heat pumps have been in use since the late 1940s. Geothermal heat pumps (GHPs) use the constant temperature of the earth as the exchange medium instead of the outside air temperature. This allows the system to reach fairly high efficiencies (300%-600%) on the coldest of winter nights, compared to 175%-250% for air-source heat pumps on cool days.
It is the opinion of Freeman Mechanical that a “piggyback” heatpump, paired with a high efficiency gas furnace, is the most cost effective choice for heating your home.
How does a heat pump work?
It’s simple…think of how your air conditioner works. It removes heat from inside of your home and moves it outside. A heat pump works the same way. In the summer, it acts as an air conditioner, removing heat from your home. In the winter months, a heat pump works in reverse, picking up heat from the outside air and moving it into your home.
The new heat pumps are surprisingly efficient to very low temperatures and have a much warmer discharge air than older models. Not to mention, operating for pennies on the dollar compared to other heating methods. When temperatures reach a point that the heat pump is no longer efficient, the thermostat automatically switches from the heat pump to your gas furnace, allowing your home to remain comfortable no matter what the temperature, with the least amount of operating cost.
Freeman Mechanical uses a trusted name in boilers. Well McLain has been one of the top boiler manufactures in the country since 1881. The companies quality and technology offers one of the most efficient boilers in today’s market. The Ultra Series Boiler boasts up to 98% efficiency!
This high of efficiency equates to substantial savings in heating costs in the winter season.
With optional equipment added, the boiler can double as a domestic hot water heater,
allowing for an almost endless supply of hot water while saving money throughout the
Other optional uses for a Well McLain boiler include:
Pool/hot tub heating
Driveway heater to melt ice
Residential, Commercial & Industrial Heating & Air Conditioning
While many parts of the country experience seasonal temperature extremes—from scorching heat in the summer to sub-zero cold in the winter—a few feet below the earth's surface the ground remains at a relatively constant temperature. Depending on latitude, ground temperatures range from 45°F to 75°F. Like a cave, this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer. The GHP takes advantage of this by exchanging heat with the earth through a ground heat exchanger.
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. Relative to air-source heat pumps, they are quieter, last longer, need little maintenance, and do not depend on the temperature of the outside air.
Even though the installation price of a geothermal system can be several times that of an air-source system of the same heating and cooling capacity, the additional costs are returned to you in energy savings in 5–10 years. (On average, a geothermal system uses 25%-50% less electricity than traditional heating and cooling systems.) System life is estimated at 25 years for the inside components and 50+ years for the ground loop. There are approximately 40,000 geothermal heat pumps installed in the United States each year.
