With the use of our state-of-the-art products, you can empower yourself and take control of your fluctuating energy costs, while making your home more comfortable than it's ever been. No matter the weather; you can save up to 60 percent on your monthly utility bills; protect the environment and greatly reduce your energy usage.
You can always buy a cheaper system, but you can't buy a better system backed by the most knowledgeable technicians in Pembroke and the surrounding area. With a coefficient (COP) of over 5 on the NEW PremiumG, every unit of energy you put into the furnace results in 5 units of energy delivered into your home. Who better to install your new GeoSmart furnace than MacKinnons? They are experts in soil conditions and fluid pumping which are major factors in the heat pump operations.
Types of Loop Systems
There are several loop configurations available. They can either be vertical, horizontal, or submerged in a nearby pond or lake. In many cases, a water well can be used instead. The best application will depend on the characteristics of your property. We can help you determine which system is best for your property.
How Does it Work?
The earth absorbs almost 50% of all solar energy and remains a nearly constant temperature of 50°F to 70°F depending on geographic location. Working with an underground loop system, geothermal heating and cooling systems utilize this constant temperature to exchange energy between your home and the earth as needed for heating and cooling.
In winter, water circulating inside a sealed underground loop system absorbs heat from the earth and carries it to the geothermal unit. Here it is compressed to a higher temperature and sent as warm air to your indoor system for circulation throughout your home.
In the summer, the system reverses and expels heat from your home into the cooler earth via the loop system. This heat exchange process is not only natural, but is a highly efficient way to create a comfortable climate in your home.
Horizontal loops are the most common type of loop system, and are commonly used in rural areas due to the land space needed for installation. An excavator will dig several trenches about six feet deep in the ground, each one up to 300 feet long. GeoSmart Energy's green geothermal pipe is placed in the trenches which are then backfilled with soil.
Vertical loops are primarily used in urban areas because they require little land space for installation. A specially designed geothermal drilling rig bores vertical holes into the ground each ranging from 180 to 540 feet deep. Geothermal pipe is inserted into each vertical bore and then the holes are filled with bentonite grout.
On properties that have a nearby lake or pond that is appropriate in size and eight feet in depth, a loop system can be submerged at the bottom of the body of water. A single trench is excavated from the home to the water and typically two pipes are inserted into it. These two pipes connect to several green geothermal pipes that are submerged at the bottom of the lake or pond.
Open loops are most commonly used on rural properties that have existing high capacity water wells. Ground water is withdrawn from an aquifer through a supply well and pumped into the heat pump, while discharged water from the heat pump is redirected into a second well and back into same the aquifer.
