Geothermal heating and cooling systems utilize the earth’s temperature to remove heat from buildings during the summer months and supply heat in the winter months. In summer, heat pumps are used to extract heat energy and deposited deep in the ground, later used to increase the efficiency of your system during the winter months. In effect, Saskatchewan homeowners can save approximately 50 to 60 percent annually on heating and cooling costs.

The Ground

A geothermal system uses energy from 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. Meaning that you have a steady supply of heat to keep you in comfort, even in the depths of the coldest winter.

The Ground Loop (Pipes)

Geothermal systems use a series of pipes buried in the ground called a ground loop. An ethanol solution is circulated through the pipes to make them highly efficient conductors of heat. In the winter, the ethanol in the pipes absorbs the heat from the ground and, now warmed up, the fluid is pumped back through the geothermal unit in the house. In the summer, the heat transfer process takes place in reverse. The fluid in the pipes leaves the house in a warm state, but after circulating underground is cooled as the pipes exchange heat with the cooler earth.

The Geothermal Unit (Heat Pump)

TThe underground loops connect to the main geothermal unit installed in your house, and connected to your home's forced air (or water radiator) system. Compatible with your home's distribution system.

How it works

 

 

Combo system

A combo geothermal system utilizes forced air as well an hydronic heat pumps to maximize home comfort.

traditional Forced air

A forced air heat pump is similar to a traditional furnace. It connects to duct work and circulates heat and cool air throughout the house.

in-floor heat

An in-floor (hydronic) geothermal boiler produces heated glycol which is circulated through pipe in a concrete floor. A great option for a heated garage or basement floor.

Vertical Ground Loop

A vertical loop field is the most typical installation process for a geothermal heat pump. The average vertical loop for a house could fit in a regular front or backyard. During a vertical loop field installation, a series of holes are drilled, each between 100 - 150 feet deep. Piping is fed down these holes and connected in a header pit. The piping is then grouted in the holes to achieve proper thermo-conductivity to the surrounding earth. Once all of the pipes are connected outside of the home, they are fed through a header trench into your home and connected to the geothermal heat pump. The average vertical loop takes 2 - 5 days to complete.

Horizontal Ground Loop

A horizontal loop installation usually occurs in more rural areas or yards with lots of space. Horizontal loops require a significant amount of land and disturb more area than a vertical loop. The average horizontal loop is approximately the size of a football field. The trenches are 8 - 10 feet deep to ensure the loop is safely below the frost line. Horizontal systems can be installed using an excavator or other ground moving equipment and can be installed in 2 - 5 days.

More Advantages of a Geothermal Heating System

Requires No Maintenance

With a properly installed geothermal heating system, the loops buried in the ground can last for decades without requiring maintenance. The rest of the geothermal system is located indoors, so it is not exposed to the elements that might cause wear and tear.

Adds Value to Your Home

With more and more potential home buyers looking for residential properties that have energy saving features such as geothermal, Saskatchewan homeowners consider a geothermal installation to be an investment rather an expense. This type of heating and cooling system can actually add value to your home, should you consider selling it in the future.

No Negative Effect on the Environment

Geothermal heating systems use heat that is already stored under the ground, so the energy produced is fully sustainable and has no negative effect on the environment. Saskatchewan homeowners are doing their part to protect the environment by equipping their homes with geothermal systems.

Requires Very Little Space

Most of the components of a geothermal system are buried in the ground and the rest can be installed in the basement or garage, so the entire system doesn't take up much space.

maximize your savings

A geothermal system is a smart investment for Saskatchewan homeowners. Considering that energy costs continue to rise, homeowners can benefit significantly from saving 40 to 60 percent annually on electricity bills. In as little as a few years, you will be able to recoup the costs you incurred for the installation of your geothermal system.

faqs

  • What is a geothermal heat pump?

    A geothermal or “ground-source” heat pump is an electrically-powered device that uses the natural heat storage ability of the earth and/or the earth’s groundwater to heat and cool your home or business at very high efficiencies.

  • How does a geothermal heat pump work?

    Like any heat pump, it moves heat energy from one place to another. A geothermal heat pump is like a refrigerator because they work using the same scientific principle. By using refrigeration, the geothermal heat pump removes heat energy stored in the earth and the earth’s groundwater and transfers it to the home.

  • How is the heat transferred from the ground to my home?

    The earth can absorb and store heat energy. To use that stored geothermal energy, it is extracted from the earth through a liquid circulated in the ground via a loop. The energy is transferred to the heat pump heat exchanger where the heat is used to heat your home. In the summer, the process is reversed, and indoor heat is extracted from your home and transferred to the earth through the liquid circulating in the loops underground.

  • Do I need separate geothermal ground loops for heating & cooling?

    No, the same loop works for both. When changing from heating to cooling, or vise versa, the flow of heat is reversed by a mechanism inside the unit.

  • How long will my loop last?

    Properly installed, these pipes will last over 50 years.

     

  • Will the loop effect my lawn & landscaping?

    No, research has proven that loops have no adverse effect on grass, trees or shrubs. Most horizontal loop installations use trenches about 3 feet wide or less. This, of course, will leave temporary bare areas that can be restored with grass seed or sod. Vertical loops require less space and result in minimal lawn damage.

  • Are there any rebates available for geothermal?

    No, at this point in time there is no provincial or federal rebate programs.

     

     

  • Are there any other loop options?

    There are two other loop options that miEnergy does not offer or recommend for its projects:

    Lake or pond loops

    A pond loop field can be installed when the property is located near a large body of fresh water such as a pond or lake. In Saskatchewan, our harsh winters require geothermal loops have access to reliable sources of energy.  If the body of water does not have the proper capacity, it will not be able to generate the energy needed to sustain proper heat throughout the winter. Also, there are environmental policies restricting the excavation of trenches from the body of water to the structure.

    Open Loops

    An open loop requires an ample source of groundwater. A well is drilled into a water source; it is circulated to the heat pump - where heat is extracted - and sent down a return well where it re-enters the water source. Open loops are less common because they require a significant and constant water source below the surface.

     

    With vertical and horizontal ground loops, miEnergy can be confident your geothermal system will operate correctly for the lifetime of the system.

  • How long will my equipment last?

    Just like any other mechanical system, the equipment will need to be replaced eventually. The manufacturer suggest a life-span of approximately 25 years.

  • Does my system come with warranty?

    Yes, all of our heat pumps come with a direct-from-manufacture warranty. The warranty is a 5 year labor and electrical with a 10 year on all major refrigeration components.

  • Do I need a supplemental source of heat?

    No, a properly designed and installed geothermal system will provide 100% heating and cooling. The system will also produce approximately 50% of your domestic hot water.
