How does geoexchange system work?

The geo-exchange system uses a heat pump to store and retrieve heat from the earth, often called a ground- source heat pump. A conventional furnace burns a fossil fuel to produce heat, a geo-exchange system transfers heat from one place to another.

What is the difference between geothermal and geoexchange?

Conversely, GeoExchange is the accurate description for a technology that utilises the ground (Geo) to a much lessor depth than geothermal as a heat source in winter and heat sink in summer (Exchange).

How much does it cost to install a geothermal system?

between $18,000 to $30,000
On average, a homeowner can expect total expenses to reach between $18,000 to $30,000 on geothermal heating and cooling cost. This cost would cover a complete geothermal installation. The price can range from $30,000 to $45,000 with high-end ground-source heat pump systems for large homes.

How deep do you dig for geothermal heating?

It requires trenches at least four feet deep. The most common layouts either use two pipes, one buried at six feet, and the other at four feet, or two pipes placed side-by-side at five feet in the ground in a two-foot wide trench.

How much does it cost to drill a geothermal well?

Geothermal Well Drilling Cost. Geothermal well drilling costs $5 to $40 per foot or $3,500 to $5,000 per well. Geothermal wells are 4” to 8” wide, 100′ to 500′ deep, and spaced 10′ to 20′ apart. Most homes need 3 to 5 boreholes on average with 300′ to 500′ of piping per ton of HVAC capacity.

Is a geothermal system worth it?

What are the pros and cons of geothermal heating? The pros would be that they are extremely efficient and will work around 400% better than a traditional furnace. This is also renewable energy so it is good for you, good for the environment, and good for your energy bill. Your energy bill will reduce significantly.

How cold can geothermal get?

Depending on latitude, ground temperatures range from 45°F (7°C) to 75°F (21°C). Like a cave, this ground temperature is warmer than the air above it during the winter and cooler than the air in the summer.
