Benefits of Earth Energy Systems

The operating costs of earth energy systems are much lower than the cost to operate a combustion furnace with an air conditioning unit. However, the cost to install a complete earth energy system can be higher than the cost to install furnace and air conditioning unit. On average, an earth energy system can save two-thirds of the cost to heat and cool with electricity.

Earth energy can provide heating in winter, cooling in summer, and year-round hot water for home use. A single system performs all necessary functions and requires only a flick of a switch to reverse the unit for a seasonal change.
 
An earth energy system can reduce greenhouse gas emissions by more than two-thirds compared to similar systems that use carbon-based fuel. However, the reductions depend on the source of electricity that is used run the system's components. It is becoming more important to reduce greenhouse gases because of international efforts to reduce global warming and climate change.
 
Earth energy systems provide constant low-level heat, which eliminates the need to change thermostats at night. Another benefit is the absence of draughts that are common with conventional forced-air heating systems.
 
Earth energy systems do not produce the odour that is found in natural gas, oil or propane furnaces. That makes earth energy systems perfect for highly-insulated buildings or for people who are allergic or sensitive to noxious gases and poor air quality.
 
Earth energy systems are located inside a building, which eliminates the adverse effects of nature and any accidents or vandalism, thereby increasing the system's life and efficiency.
 
No penetrations through the building's walls or roof increase energy performance and reduce the risk of structural damage.
 
Because there is no combustion, earth energy systems cannot explode and there is no need to store fuel. Insurance companies often provide a discount on policies that use earth energy.
 
If you install an earth energy system in a commercial or industrial building, you eliminate the need for a flat roof and cooling towers. That allows architects to increase the aesthetic appeal of the building's design.
 
Earth energy systems can deliver heat to one room and simultaneously provide cooling to an adjacent room. This is extremely useful in institutional buildings such as schools.
 
In commercial or industrial buildings, earth energy systems reduce the need for mechanical space. That allows space to be used for more productive purposes. In many cases, the cost savings from reduced overhead space in the ceiling and the mechanical room can offset any increased cost for the installation of the system.
