The Ground

A geothermal HVAC system uses the sun's energy stored in the earth, to keep your home or place of work in comfort 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 you will have a constant, natural supply of heat to keep you comfortable, even in the depths of the coldest winter.

The Pipes

An ethanol solution is circulated through a series of pipes buried underground, resulted in a highly efficient conductor of heat. In winter the ethanol absorbs heat from the ground and the warmed fluid is pumped back through the geothermal unit into the house. In summer, the heat transfer process takes place in reverse. The fluid in the pipes leaves the house in a warm state, circulates underground and is cooled as the pipes exchange heat with the cooler earth.

The Geothermal Unit

The underground piping connects to the geothermal unit installed in your house and is connected to your home's forced air (or water radiator) system. See options to the left for details on NextEnergy geothermal systems and how they are compatible with your home’s distribution system.

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

NextEnergy'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 efficiency and performance.

Water-to-Water-in-Floor

Designed for use in heating or cooling applications requiring high efficiency, the Genesis GSW is the perfect selection. Commonly used in residential applications requiring energy efficient water-to-water heat transfer, the Genesis GSW is used to pre-heat or cool make-up air; or can be installed as a stand-alone boiler/chiller in hydronic heating applications such as radiant floors and fan coil heating/cooling.

The Distribution System

Heating In Winter

After the pipes have completed the heat transfer, and the geothermal unit has maximized the heat value of the circulated fluid - the heat is then drawn off the heat exchanger in the unit and circulated throughout the house using the existing distribution system.

Cooling In Summer

In summer, the process is reversed. The hot air in the house is essentially absorbed by the geothermal unit which now circulates much cooler pipe fluid. The heat is transferred first to the pipes then to the ground outside before returning, cooled, to the house.

Distribution

The geothermal unit is connected to the home's 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. Outdoor air conditioning units, often noisy and enerty wasters, are not required.

Comfort

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 years.

The Environment

Geothermal systems use a renewable resource, the earth, which is efficient and non-polluting. Replacing a fossil fuel system with geothermal immediately cuts your household energy emissions footprint by 50%, the equivalent of taking four cars off the road. Federal and provincial governments recognize the important role geothermal plays in reducing home energy use, and have created rebate programs to facilitate installation.
