Geothermal Heating: 10 Common Questions Answered

February 24, 2026

Are you considering a geothermal heating system for your home? This innovative and energy-efficient technology has many benefits, but it also raises a few questions. In this article, we’ll answer 10 of the most common questions about geothermal heating, so you can learn whether it’s worth the investment!

HOW DOES A GEOTHERMAL SYSTEM WORK?

A geothermal heating system works by tapping into the natural heat of the earth. This heat is transferred to a fluid that circulates through a series of pipes, either in an underground loop system or within a water source. The fluid then warms a heat pump, which transfers the heat into your home, creating a warm and comfortable living environment. At Link ClimateCare, we can help you determine if geothermal is the right fit for your property and professionally design and install a system that delivers reliable, energy-efficient comfort for years to come.

WHAT ARE THE PROS AND CONS OF GEOTHERMAL HEATING?

One of the main benefits of geothermal heating is that it is highly efficient, using only a small amount of electricity to transfer the heat from the earth to the building. Additionally, geothermal systems have a long lifespan, typically lasting 15-30 years or more. On the downside, the upfront costs of installing a geothermal system can be high, and the systems require a significant amount of space for the loop or water source.

HOW MUCH DOES IT COST TO INSTALL A GEOTHERMAL HEATING SYSTEM?

On average, the cost of installing a geothermal heating system can range from $25,000 to over $40,000, including labour and equipment. The true cost will depend on factors such as the size of your home, the system you choose, available land and water, the soil type on your property, and more.

ARE GEOTHERMAL HEATING SYSTEMS MORE ENERGY EFFICIENT THAN TRADITIONAL FURNACES?

Yes, geothermal heating systems are highly energy efficient, using only a small amount of electricity to transfer heat from the earth to the building. In fact, geothermal heating systems can be up to five times more efficient than traditional heating systems, which makes them a great choice for homeowners looking to save money on their energy bills.

DOES GEOTHERMAL HEATING REQUIRE MAINTENANCE?

Like any heating system, a geothermal system will require some maintenance over its lifespan. This may include cleaning the heat exchanger, checking the fluid levels, and replacing parts as needed. However, the maintenance requirements for geothermal systems are generally lower than those of traditional furnaces and boilers.

DOES GEOTHERMAL HEATING WORK IN COLD CLIMATES?

Yes, geothermal heating systems are effective in cold climates, including throughout Canada and Ontario. In fact, these systems can be especially useful in areas with harsh winters, as they provide a reliable and efficient source of heat. Despite air temperature fluctuations, the temperature about 1-2 m underground stays relatively constant at around 12 °C.

WHAT GOVERNMENT REBATES ARE AVAILABLE FOR GEOTHERMAL HEATING SYSTEMS?

Fortunately, there are multiple options for government rebates, grants, and tax credits when you make the switch to geothermal. For instance, the Canada Greener Homes Initiative provides grants of up to $5,600 for eligible retrofits and access to interest-free loans of up to $40,000 to help you start the process.


Your provincial and local governments may also offer incentives for switching to greener energy sources.


DOES A GEOTHERMAL SYSTEM REQUIRE BACKUP HEAT?

Generally, a geothermal heating system requires only a small amount of backup heat, on extremely cold days. Unlike an air-source heat pump, geothermal heat pumps use a more consistent source of heat, ensuring their efficiency is maintained. This guarantees comfortable, year-round warmth for your household.

HOW LONG DOES A GEOTHERMAL HEATING SYSTEM LAST?

Geothermal heating systems are designed to be long-lasting, with a typical lifespan of 15-30 years or more. This means that once you have installed a geothermal system, you can enjoy the benefits of this efficient and sustainable heating technology for many years to come.

ARE GEOTHERMAL HEATING SYSTEMS WORTH THE INVESTMENT?

To fully evaluate a geothermal system’s investment potential, you must consider factors like installation cost, energy needs, and long-term financial goals. However, for many homeowners, the benefits of geothermal heating, including increased energy efficiency and reduced carbon footprint, make it a smart investment in the long run. Plus, with government incentives and assistance, the upfront costs can become much easier to manage.

A smart thermostat is more than a convenience; it’s the control centre for your home’s biggest energy loads. In a typical Canadian house, space heating and cooling account for about two-thirds of total energy use, so smarter control directly shrinks bills and emissions. This guide explains how smart thermostats work, where savings come from (obvious and hidden), key compatibility checks for Ontario homes, and how to choose with confidence.  From Dial To Digital: How Thermostats Evolved Early bimetal dials simply turned systems on and off. Programmable units added time-based setbacks, letting Canadians automate lower temperatures overnight or when away. Now, smart thermostats build on that idea with learning schedules, occupancy sensing, remote control, and energy reports. These features are also standardized under Canada’s ENERGY STAR program . With smart thermostats, control isn’t limited to the hub on your wall. You can access it via smartphones and device apps, wherever you are, as long as you have internet. Why An Eco-Friendly Control Centre Matters (Not Just Appliances) Because heating uses ~63% of the average home’s energy and cooling adds a bit more, precise setpoints and schedules have an outsized impact. An ENERGY STAR-certified smart thermostat adjusts to energy-saving temperatures when you’re asleep or away, and Natural Resources Canada (NRCan) notes that typical users can save around 8% on heating/cooling costs with smart control used properly. When you pair that with energy-efficient upgrades such as a new furnace (or even better, a heat pump), savings add up! 3 Obvious Ways A Smart Thermostat Saves Energy Automated scheduling & learning: Builds routines that avoid heating or cooling an empty home. Remote access: Change setpoints from your phone if plans change. Actionable feedback: ENERGY STAR models provide usage data so you can spot waste and fine-tune settings. With kilowatt hours saved, that translates to more money in your bank. The Less-Obvious (But Powerful) Savings Demand response participation: Ontario’s Peak Perks uses brief, opt-out thermostat adjustments on the hottest weekdays to lower provincial peak demand, improving grid reliability and cutting peak-time emissions intensity. More than 200,000 residents enrolled by January 2025. System-friendly operation: Features like gradual temperature recovery and adaptive algorithms can reduce short-cycling and overshoots that waste energy, especially with variable-speed equipment. Where A Smart Thermostat Helps Most Furnace/AC systems: Easy wins from learned schedules and setbacks; look for ENERGY STAR certification. Air-source heat pumps: Pairing with a compatible smart thermostat maintains comfort and elevates efficiency; NRCan explicitly recommends smart control alongside heat pumps. Electric baseboard or in-floor electric heat: You need a line-voltage smart thermostat (120/240V). Standard low-voltage (24V) models, like many popular Wi-Fi thermostats, are not compatible. Provinces, including Ontario, have performance standards (CSA C828) for line-voltage thermostats, and NRCan is considering federal regulation . Hydronic/radiant systems: Because boilers and radiant systems respond slowly, setback depth and timing should be conservative. Smart controls allow fine-tuned, gradual changes. Real-World-Based Canadian Setpoints For the winter, Statistics Canada and ClimateCare guidance align with keeping 20–22 °C while home and awake, and 16–18 °C when asleep or away. These are settings a smart thermostat can automate consistently. During the summer, add about 3-4 degrees to that guideline. Features That Signal Eco-Performance There are countless models of “smart” thermostats out there. Some, on Amazon and other sites, might look like they comply with Canadian standards, but often don’t when the price seems too good to be true. That’s why you should look for: ENERGY STAR Certified: Ensures baseline capabilities like learning, occupancy features, and energy reporting verified for Canada. Occupancy/room sensors: Avoid over-conditioning unoccupied spaces; remote sensors improve comfort with fewer runtime hours. Demand-response ready: Eligible for offers and programs such as Ontario’s Peak Perks (check the model list). Integration with heat pumps: Look for controls that manage auxiliary/backup heat intelligently to prevent expensive electric strip heat from taking over. Compatibility And Installation Checks Not all smart thermostats are compatible with all systems. These considerations should be taken into account when purchasing: System voltage: Confirm 24V low-voltage (common for furnace/ AC /heat pump) versus line-voltage (baseboard, electric radiant). Choose the right class of thermostat. C-wire power: Many smart models need a common wire—professional installation can add one or use approved adapters. Link ClimateCare can assess wiring and configure advanced features for your equipment. Eligibility for programs & incentives: Ontario’s evolving efficiency programs periodically support smart thermostats and demand-response enrollment; always verify current eligibility. Privacy And Data Concerns from A Canadian Lens Smart thermostats process occupancy patterns, schedules and sometimes location data. Canada’s Office of the Privacy Commissioner (OPC) advises consumers to review what information is collected, how it’s shared, and whether you can delete it. To operate in Canada, manufacturers must follow PIPEDA and best-practice safeguards. Use strong passwords, enable updates, and review app permissions annually at least. Ready to Switch? Here’s a Buyer’s Checklist Confirm system type: Low-voltage vs line-voltage; heat pump vs furnace. Choose ENERGY STAR certified models for proven features and performance. Check demand-response eligibility (Peak Perks in Ontario) and enroll if available. Plan your schedule: Aim for 20–22 °C occupied and 16–18 °C asleep/away, then fine-tune in the winter. 3-4 degrees higher for summer. Review privacy settings and firmware update policies. Consider home data tools: Ontario supports Green Button apps to visualize and manage use alongside your thermostat. Our Frequently Asked Questions About Smart Thermostats Do smart thermostats actually lower emissions in Ontario? Yes. Cutting heating/cooling runtime reduces household energy use directly. Enrolling in Peak Perks also trims provincial peak demand, which supports reliability and reduces the need for peak-hour gas generation. What if I have baseboard heat? Choose a line-voltage smart thermostat designed for 120/240V heaters. A conventional low-voltage smart thermostat will not work safely or correctly. Can smart thermostats work with heat pumps? Yes, and usually very well. Canadian regulators even encourage this pairing. Select a model with heat-pump-specific settings to control auxiliary heat efficiently.
