WHY USE OUR SYSTEM?
Ground Source Heat Pumps (GSHP) all do the same thing – they all pull warmth out of the ground for heating, and pump heat into the ground for cooling. But there are different ways of doing so.
An open system draws ground water into the heat exchanger and discharges it back into the environment; closed systems cycle coolant through the ground loop. Closed systems are more efficient and don’t interfere with ground water supplies. We use a closed system.
Some installers lay a horizontal field of coiled pipes, usually not an option for residential customers. Our vertical installation takes less space and has the lowest impact on the surrounding environment.
Most Earth Energy Systems use water or a water-antifreeze mixture. Because the heat has to be concentrated before it can be removed from or used to warm up your home, these systems also need a secondary heat exchanger. We skip this step by circulating the refrigerant directly between the ground loop and the heat exchanger.
Direct Expansion systems greatly enhance efficiency and have lower maintenance requirements. It’s the most efficient and cost-effective way to do the job.
And best of all, our system uses a chlorine-free, non-ozone depleting, environmentally-friendly refrigerant.
SOME OF THE BENEFITS OF EARTH ENERGY SYSTEMS…
COST-EFFECTIVE:
The more you are paying to heat and cool your home or business now, the greater your annual savings will be, and the faster you will recover your initial investment. Because of the high and ever-increasing cost of oil, natural gas and electricity, the average homeowner putting in a new system can expect to recover their initial investment in somewhere between five and ten years.
Payback is even faster for larger-scale installations. Office buildings can recoup their installation costs in the first year, because an earth energy system is often cheaper to install than conventional heating and cooling equipment. Arenas and curling rinks using Ground Source Heat Pumps show a payback period in the 1-5 year range, while high schools tend to fall into the 4-6 year range. According to Natural Resources Canada, the average payback period for commercial installations is approximately 6 years, “with most falling in the 4 to 8 year range.”
RESPONSIBLE:
Earth Energy Systems have an exceptionally low environmental impact. The ground loop is installed in boreholes - just like an artesian well, except that nothing is being pumped into or out of the ground. The drilling area is small, and all of the exterior piping is buried. The system can use modern, non-ozone depleting refrigerants in accordance with the Montreal Protocol; and in a DX system, it never comes into contact with air or water.
EFFICIENT:
Geothermal heat pump systems are one of the most efficient means of heating and cooling your home or business. In Canada, earth-energy systems can provide savings of up to 60-75% when compared to using fossil fuels and electrical systems for heating and cooling. During the cooling season, the system can scavenge heat from your house to produce domestic hot water, basically for free.
COMFORTABLE:
An electric or fossil-fuel furnace produces hot air at about 50-60ºC. This can create “hot spots” throughout a building. Earth energy systems produce warm air at about 35ºC, for a more comfortable environment; and because they operate best when they operate continuously, there are no sudden blasts of hot or cold air. Two-speed compressors and multi-speed fans are the most efficient of all systems, providing only as much heating or cooling as you need. With automatic thermostatic control, you get heating and cooling when and where you need it. And the compressor is quiet and sound-insulated, avoiding the noise usually associated with outdoor air conditioners.
RELIABLE:
Earth energy systems may be the most reliable heating and cooling technologies available. The ground loop has a life expectancy of 25-30 years or more. All of the control components are solid-state. The only significant moving part is the compressor, and this generally lasts for upwards of twenty years.
In a recent study of service and maintenance at 38 commercial installations, only six corrective actions were required per 100 years of unit operation.
Direct Expansion earth energy systems are quieter, more reliable, longer-lasting, and have lower maintenance requirements.
All of the equipment is underground or indoors, out of the reach of weather and mischief-makers.
There’s just a lot less to go wrong.
