Heat and cool your home while reducing your carbon emissions. Ground-source heat pumps (GSHPs), also known as home geothermal, use the underground temperature of the earth to draw heat to warm your home more efficiently, which can reduce heating costs by up to 50 per cent. In the summer, it reverses the cycle to keep your home cool and comfortable.

Who Can Participate

Using a participating contractor, Ontario homeowners who live in a detached home, townhouse or semi are able to take part. The rebate is also available to homeowners of new custom home builds. If you are a landlord, you must obtain permission from your tenants.


What You Get

Receive up to $20,000 in rebates for an ENERGY STAR® Certified GSHP which can save you up to 50 per cent on heating costs. Rebates are available for three models:

Horizontal closed-loop heat pump:

Receive $2,000/loop ton up to $15,000

If your home is located on sufficient land this heat pump may be the most cost effective for you. Pipes are laid in trenches, which requires minimum 600 feet of ¾” or 1” HDPE pipe per ton or 500 feet of 1-¼” HDPE pipe per ton.

Pond closed-loop heat pump:

Receive $2,000/loop ton up to $15,000

Have a property with a pond? If it’s the right size and depth this heat pump may be the most cost-effective. Heat pump pipes are laid at least eight feet below the pond surface and connect to your home.

Vertical closed-loop heat pump:

Receive $3,000/loop ton up to $20,000

This heat pump is most often used where there is less space available or soil is too shallow or difficult to trench. Pipes require minimum 200 feet of borehole and 400 feet of ¾” or 1” HDPE pipe per ton or 180 feet of borehole and 360 feet of 1-¼” HDPE pipe per ton.

Already have a heat pump and looking to update? Receive up to $4,500 to replace or repair your ground-source heat pump. Systems must be at least 20 years old.

Receive up to $750/ton of heat pump when replacing an existing ground source heat pump system or $750/loop ton for ground loop repair.

Benefits

Reduce your carbon footprint; ground-source heat pumps are the most eco-friendly space heating on the market.

Moving heat uses less energy than generating heat, making heat pumps more efficient than traditional heating systems.

No need for a dehumidifier. A ground-source heat pump’s cooling cycle provides dehumidification, allowing you to save on energy use.

Geothermal 101

While air temperatures rise and fall throughout the year, the temperature a few feet below ground is a constant 10-15°C. That’s why a Ground-Source Heat Pump (GSHP) can heat, cool, dehumidify and supply hot water efficiently, no matter the season.

Taking heat straight from the source

GSHP collect natural heat from below the earth’s surface using a continuous loop of plastic piping. Depending on the size of the home, property and soil conditions the pipes are placed vertically or horizontally underground.

During the heating cycle, water mixed with anti-freeze is pumped through pipes buried in the ground outside your home. Through a heat exchanger the earth’s heat is delivered as warm air through ducts in your home.

On the cooling cycle, the system works in reverse, removing heat and humidity from your home and transferring it back into the ground – just like an air conditioner only much more efficient.

Get in the loop

GSHP are sized in loop tons. An average home might require a three-ton (three loop) system, while a larger home might require a six ton (six loop) system.

An investment for today and the future

Underground components of GSHPs can last up to 75 years and indoor components about 25 years. A new system typically pays itself off in energy savings in five to ten years.

Ground-Source Heat Pumps Offer More than air

Depending on the system, GSHP can do more than heat and cool. Some systems can heat water which can reduce water heating bills. They are also dehumidifiers, taking away the need for a separate system.

The scoop on EER and COP

Qualifying GreenON Rebates ground-source heat pumps must meet minimum Energy Efficiency Ratio (EER) and Coefficient of Performance (COP) rating. What are EER and COP?

  • Coefficient of Performance (COP): COP measures heating efficiency; the ratio of total heating capacity to electrical energy input. Look for efficiency ratings of 3.1-4.9

  • Energy Efficiency Ratio (EER) efficiency ratings: EER measures cooling efficiency; the ratio of the total cooling capacity to electrical energy input. Look for efficiency ratings of 16.1-25.8

Minimum ratings required for each eligible GSHP system:

 
Closed Loop Ground-Source Heat Pump – Horizontal Loops
Closed Loop Water to Air System Minimum 17.1 EER and 3.6 COP
Closed Loop Water to Water system Minimum 16.1 EER and 3.1 COP
Closed Loop Ground-Source Heat Pump – Vertical Loops
Closed Loop Water to Air System Minimum 17.1 EER and 3.6 COP
Closed Loop Water to Water system Minimum 16.1 EER and 3.1 COP
Closed Loop Ground-Source Heat Pump – Pond Loops
Closed Loop Water to Air System Minimum 17.1 EER and 3.6 COP
Closed Loop Water to Water system Minimum 16.1 EER and 3.1 COP

Go with a pro

GSHPs require specialized design and installation. Be sure to obtain quotes from at least three contractors or suppliers to compare and check references.

Questions to ask your contractor:

  • What energy savings can I expect from my new system?

  • Which rebates do I qualify for?

  • Will a GSHP handle my total heating and cooling needs or will I need supplementary heating?

  • What is the warranty coverage and maintenance schedule?

  • Who will be responsible for landscaping work after the loops are completed?
