What is a Geothermal Heating and Cooling System?

The thermal energy of the Earth is captured using geothermal technology. In contrast to the summer and winter extremes of the ambient air above ground, the Earth’s temperature is nearly constant just a few feet below the surface.

More deeply underground, the temperature rises for every foot of depth. Some areas may experience higher temperatures and pockets of superheated water and steam that are much closer to the surface due to tectonic and volcanic activity.

In order to move heat in support of end uses like space heating, space cooling, and even water heating, a ground source heat pump makes use of the temperature difference that naturally exists between the above-ground air and the subsurface soil. A heat pump and several subterranean pipes make up a ground source or geothermal system. The pipes can be installed in vertical boreholes that go several hundred feet below earth or in horizontal trenches that are barely below the surface. To transfer heat from one location to another, the heat pump pumps a heat-conveying fluid, occasionally water, through the pipes.

Geothermal heat pump operates similarly to a conventional heat pump by capturing and transporting heat between interior and outdoors using high-pressure refrigerant. Geothermal systems use vast loops of underground pipe filled with liquid to transport heat.

How Geothermal Heat Pumps Work?

Buildings can be heated and cooled using geothermal heat pumps, which take advantage of the earth’s relatively constant temperature. The temperature of the earth is 50 to 60 degrees Fahrenheit at a depth of just a few feet. In winter and summer, the temperature beneath the earth is higher than the air circling over it. A system with a significantly higher efficiency called Geo solar is sometimes created by combining solar heating with geothermal heat pumps. Earth energy systems, ground source heat pumps, Geo exchange, and earth-coupled are a few terms for geothermal heat pumps.

Geothermal heat pumps utilize this energy that exists below the surface of the earth to heat and cool buildings. Since the 1940s, geothermal heat pumps have been in operation. Instead, using the temperature of the outside air to heat homes and workplaces in the winter, geothermal heat pumps use the heat stored beneath the earth’s crust.

As heat is taken from the heat exchanger by the heat pump system and pumped into the indoor air delivery system during the winter, the heat beneath the earth is used as a medium to heat dwellings. In the summer, the procedure is reversed as the heat pump transfers heat from the inside air to the heat exchanger and the system releases the heat into the ground. In order to have hot water throughout the summer, the heat pump’s heat can also be used to heat water.

Yellow furnace burner flame must be blue. Flickering and yellow flames indicate that the ratio of fuel and air is incorrect and indicate a dangerous condition in which the furnace is producing poisonous carbon monoxide.

Carbon monoxide is an odorless, tasteless gas that causes death if inhaled for a long period of time. You should always have a CO detector installed around the furnace and inside your house to warn you when CO is detected.

Main Components of Geothermal Heating and Cooling System

Geothermal systems are made of three main components:

Ground Loop

Ground loop is a plumbing infrastructure which is a closed loop or an open loop to transfer heat from ground to the house in heating mode or deliver heat from the house to the ground in the cooling mode.

Heat Pump

Heat pump is extracting heat from the ground loop or the indoor air, (depending on whether heating or cooling is required) and exchanges heat with the ground loop system.

Distribution System

In a forced-air system, distribution system delivers warm or cooled air throughout the house via duct work and using a blower fan. In hydronic systems, a network of piping filled with water distributes heat throughout the house.

Geothermal Ground Loop Configurations

Geothermal systems are either a close loop or an open loop system. The most common ground loop in Toronto and GTA are closed loop systems.

Geothermal Closed-Loop Systems

The majority of closed-loop geothermal heat pumps circulate an antifreeze solution via a loop that is buried in the ground or submerged in water and is often made of high-density plastic-type tubing. Between the heat pump’s refrigerant and the antifreeze solution in the closed loop, a heat exchanger transports heat.

One kind of closed-loop system, known as direct exchange, pumps the refrigerant through copper tubing that is buried in the ground in either a horizontal or vertical orientation instead of using a heat exchanger. The optimal conditions for direct exchange systems are moist soils and a larger compressor; nevertheless, you should avoid placing them in soils that can corrode the copper tubing.

Horizontal closed loop systems

Residential installations, especially new development where sufficient land is available, are typically the most cost-effective for this type of installation. Trenches that are at least four feet deep are necessary. The two most popular configurations involve either two pipes and four pipes configuration.

Vertical Closed Loop

Vertical systems are best for homes with limited available land. Vertical loops are also employed since they cause the least amount of disruption to the existing landscaping. Holes between 100 and 400 feet deep, spaced about 20 feet apart, are drilled for a vertical system. Two pipes will be inserted into the hole and connected together by a U-bend assembly at the bottom to form a loop. The horizontal pipe then will be connected to the geothermal heat pump using horizontal pipes.
