Geothermal Heat Pump System

A geothermal pump is a great renewable source of energy to do the optimal heating or cooling. The system uses the natural heat stored within the earth to facilitate the heating process whereas the time of summers act as a sink to absorb the excessive heat.

Our heat pump system is a utility appliance that smartly make use of the natural heat without posing any harmful effect on our environment. The beneficial aspect of heat pump system serves the aspect of your comfort, pocket and environment on the whole.

Green Air has taken the stride of moving into the direction of renewable energy sources to let the earth restore its natural and healthy form!

What is Geothermal energy?

Geothermal energy is thermal energy generated and stored in the Earth. Thermal energy is energy that determines the temperature of matter. Earth’s geothermal energy originates from the original formation of the planet (20%) and from radioactive decay of minerals (80%). The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface.

Types of Geothermal Heat Pump Systems

There are four basic types of ground loop systems. Three of these—horizontal, vertical, and pond/lake—are closed-loop systems.

The type of heat pump system will depend upon the climate, soil conditions, available land, and local installation costs at the site. All of these approaches can be used for residential and commercial building applications.

Closed-Loop Systems


This type of installation is generally most cost-effective for residential installations, particularly for new construction where sufficient land is available.

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.

The Slinky™ method of looping pipe allows more pipe in a shorter trench, which cuts down on installation costs and makes horizontal installation possible in areas it would not be with conventional horizontal applications.

Large commercial buildings and schools often use vertical systems because the land area required for horizontal loops would be prohibitive.

Vertical loops are also used where the soil is too shallow for trenching, and they minimize the disturbance to existing landscaping.

For a vertical system, holes (approximately four inches in diameter) are drilled about 20 feet apart and 100–400 feet deep. Into these holes go two pipes that are connected at the bottom with a U-bend to form a loop. The vertical loops are connected with horizontal pipe (i.e., manifold), placed in trenches, and connected to the heat pump in the building.

If the site has an adequate water body, this may be the lowest cost option.

A supply line pipe is run underground from the building to the water and coiled into circles at least eight feet under the surface to prevent freezing. The coils should only be placed in a water source that meets minimum volume, depth, and quality criteria.

Open-Loop System

This type of system uses well or surface body water as the heat exchange fluid that circulates directly through the GHP system. Once it has circulated through the system, the water returns to the ground through the well, recharge well, or surface discharge.

This option is obviously practical only where there is an adequate supply of relatively clean water, and all local codes and regulations regarding groundwater discharge are met.
