A Core One Mechanical Group Inc. system makes use of the largest source of energy available – the ground beneath your feet.
- The Ground
A geothermal system uses the energy of the sun, stored in the earth, to keep you in comfort all year round. Even in the winter, when a blanket of snow covers the ground, the earth’s temperature remains approximately 10°C (50°F) at only six feet below the surface. This means that you have a steady supply of heat to keep you in comfort, even in the depths of the coldest winter.
- The Pipes
A series of pipes buried in the ground. An glycol solution (antifreeze) is circulated through the pipes to make them highly efficient conductors of heat. In the winter, the water and glycol solution in the pipes absorbs the heat from the ground and, now warmed up, the fluid is pumped back through the geothermal unit or heat pump in the building. In the summer, the heat transfer process takes place in reverse. The fluid in the pipes leaves the building at a wram state, but after circulating underground, is cooled as the pipes exchange heat with the cooler earth.
- The Geothermal Unit
The underground loops connect to the main geothermal units installed in your building, and is connected to your building air distribution systems, (or water radiator) system. Compatible with your buildings distribution system: See options to the left for details on Core One Mechanical Group Inc. geothermal systems.
- Forced Air
As our top performer, the Tranquility 27™ forced-air heat pump delivers the highest efficiency ratings in the industry. Self regulating two stage technology allows the Tranquility 27™ to operate at the most efficient speed for all weather conditions. Equipped with an electronic variable speed fan motor (ICM2), the Tranquility 27™ controls system air flow to assure high operating efficiency and superior dehumidification.
- Water to Water
Core One Mechanical Group Inc.’s new Tranquility THW™ water-to-water R410A high temperature heat pump provides high temperature output (140°F), internal controls, and factory-installed options. The Tranquility THW™ includes a special high temperature scroll compressor coupled with heat exchangers designed specifically for water heating, which results in unmatched efficiencies and performance.
Designed for use in heating or cooling applications requiring high efficiency performance, the Genesis GSW is the perfect selection. Commonly used commercial applications that require energy efficient water to water heat transfer, the Genesis GSW can be used to pre-heat or cool make-up air or can be installed as a stand-alone boiler / chiller in most hydronic heating applications such as radiant floors and fan coil heating / cooling.
The Distribution System
- Heating In Winter
After the pipes have done the heat transfer, and the geothermal unit has done its work maximizing the heat value of the circulated fluid, the heat is then drawn off the heat exchanger in the unit and circulated throughout the building using the existing distribution system.
- Cooling In Summer
In the summer, the process is reversed. The hot air in the building is essentially absorbed by the geothermal unit which now circulates much cooler pipe fluid. The heat is transferred first through the refrigerant piping, then through the building groud loop piping, then to the ground outside before returning, cooled, to the building.
The geothermal unit can be connected to the buildings existing heating/cooling distribution system, whether it’s gravity or forced air, water-based (typically with radiators) or water-to-water in-floor radiant.
- Low Maintenance
Cleaning the electrostatic filter once a month is all that’s needed to keep the system in good running order.
- Quiet Operation
Pumps quietly circulate fluid through the heat exchanger. No combustion or forced-flame noise is heard. An outdoor air conditioning unit, (Condensers) often noisy, is not required.
Geothermal systems eliminate indoor temperature swings and humidity changes that often occur with traditional systems. In addition, the occasional odour caused by combustion of fossil fuel will also be eliminated.
- Long System Life
Geothermal units have a life expectancy of at least 20- 25 years.
Geothermal systems use a renewable resource, the earth, which is efficient and non-polluting. Replacing a fossil fuel system with geothermal immediately cuts your operating cost and energy emissions by nearly 50%, the equivalent of taking four cars off the road per heat pump. Federal and provincial governments recognize the important role that geothermal plays in reducing building energy use, and have created rebate programs to facilitate installation.
