How Do Heat Pumps Work?

Heat pumps operate through heat transfer utilizing refrigerant and electricity. During winter, they extract heat from available sources such as air, soil, or water, and move that heat into your home.

The advantages of using a heat pump instead of generating heat are considerable:

• Energy-efficient, achieving up to 140 percent efficiency
• Safe (no risk of carbon monoxide poisoning or natural gas leaks)
• Sustainable (unlike fossil fuels, heat pump energy sources are renewable)
• Cost-effective, leading to reduced utility bills

Given the harsh winters in Canada, it is generally necessary to have a supplemental heating source, which can be provided by a combination of a heat pump and conventional furnace/air handler or a small electric auxiliary heater in ductless systems.

Designed with Hyper-Heat Inverter (H2i) technology, Mitsubishi heat pumps can deliver heat down to temperatures as low as -30C in many models.

As your primary heating source, a cold climate heat pump can substantially improve your energy savings and decrease monthly utility costs.

How Does a Heat Pump Work in Winter?

Cold climate heat pumps capture heat from outdoor air or the ground (as in geothermal systems) and channel it inside to warm your home. To optimize performance through the heating season, selecting a model equipped with variable speed compressors is advisable, especially for regions like Ontario that see a wide temperature range.

Here’s a breakdown of how heat pumps operate in frigid conditions:

• Evaporation: The cycle starts at the outdoor unit (the evaporator), where a refrigerant absorbs heat from the air, evaporating into a low-pressure gas.
• Compression: The compressor raises the pressure of the refrigerant gas, which also increases its temperature, sending it into the indoor coil.
• Condensation: The hot refrigerant releases heat indoors as it condenses back into a liquid, warming the space.
• Expansion Valve: The liquid refrigerant passes through an expansion valve, lowering its pressure and temperature before returning to the outdoor coil to restart the cycle.
• Reversing Valve: In certain systems, this component allows the heat pump to switch between heating and cooling modes.

Overall, cold climate heat pumps provide an energy-efficient and eco-friendly solution, as they focus on moving heat rather than generating it from fuel sources, making it a cost-effective heating option for Canada’s colder regions.

Are There Different Types Of Heat Pumps?

Yes, heat pumps are categorized into three types: air source, water source, and geothermal. The main distinction lies in their heat source rather than their operation method.

Air-Source Heat Pump

These can be either ducted or ductless. Air-source heat pumps transfer heat to and from the outdoor air, providing both heating and cooling effectively.

They are known for being quiet, affordable, and energy-efficient.

Ducted: Similar to conventional HVAC systems, these require both indoor and outdoor units.

Ductless: These systems feature a single outdoor unit with several indoor heads mounted throughout the home.

Water-Source Heat Pump

These systems utilize water from sources like wells or nearby bodies of water for heat exchange. They are lesser-known in Ottawa but can be effective.

Geothermal Heat Pump

Geothermal pumps draw energy from the earth's constant temperature. They are more complex to install, making them less common in urban settings like Ottawa.

Are Heat Pumps Efficient?

Heat pumps are highly efficient heating systems. They generate more energy than they consume, achieving energy efficiency rates of up to 140 percent, surpassing other HVAC solutions by a significant margin. Not only do heat pumps heat your home in winter, but they also provide cooling in summer. When considering whether to replace an old air conditioning unit, learn more about the benefits of heat pumps for your Ottawa residence.

For optimal efficiency, choose a variable-speed heat pump as opposed to a single-speed variant. The former can adjust its operation based on real-time heating or cooling needs in your home.

Cold climate heat pumps also excel in efficiency, with select models capable of providing effective heating even at -30C.

Are There Rebates For Heat Pumps?

Unfortunately, as of now, there are no available rebates for heat pumps. The Canada Greener Homes Grant has been discontinued and is no longer accepting new applicants.

Previously, the initiative provided:

• An initial EnerGuide evaluation that guides homeowners on efficient retrofitting
• Rebates of up to $10,600 for completed energy-efficient home improvements
• Interest-free loans for up to $40,000 to aid in upgrades

Do I Need To Worry About Sizing A Heat Pump?

Proper sizing is crucial for ensuring that your heat pump functions efficiently and offers maximum comfort.

Installing an undersized heat pump can lead to inadequate energy efficiency and overworking your system, while an oversized pump can cause short-cycling and excess heat generation.

How Often Should I Perform Maintenance On My Heat Pump?

The maintenance routine for your heat pump is akin to that of a traditional furnace:

At least once a month: Check and replace air filters as needed.

Once a year: Schedule a professional inspection and tune-up to ensure the heat pump is performing at peak efficiency.

For expert maintenance at an accessible rate, consider enrolling in our maintenance plan, which includes HVAC tune-ups and prioritizes repairs.
