Are you a homeowner in Ontario looking to make a smart and eco-friendly choice when it comes to heating and cooling your home? Whether you’re facing the sweltering heat of summer or the frigid chill of winter, finding the right HVAC solution is incredibly important. 

Selecting the right heat pump is not just a matter of comfort, it’s an investment in your home’s sustainability and your family’s well-being.

Throughout this heat pump buying guide, we’ll walk you through the intricacies of heat pumps, from understanding how to choose the right type for your home, sizing it correctly, and maximizing its efficiency. 

Let’s begin the journey towards a more comfortable, sustainable, and cost-effective home heating and cooling solution!

Types of Heat Pumps

A heat pump is an alternative to traditional HVAC systems that offers numerous benefits to homeowners looking to heat and cool their homes. 

Heating-wise, heat pumps are different from furnaces and boilers because they only use a small amount of energy to move heat indoors. This two-in-one system also uses less energy to cool down households while generating almost zero gas emissions. They can help you decrease your carbon footprint and save money at the same time.  

Heat pumps vary based on what energy source they use for heat compression. Some common types are as follows: 

1. Air-Source Heat Pumps (ASHP)

This type of heat pump is the most common in Ontario households. Also referred to as air-to-air heat pumps, they work by extracting heat from the outside air and transferring it into your home during the heating season. In the summer, they can reverse the process to provide cooling. It can be ducted or ductless.

2. Ground-Source Heat Pumps (GSHP)

Ground-source heat pumps, also called geothermal heat pumps, are known for their renewable process. Instead of air, this heating system pulls heat from the earth, groundwater, or both to warm the coils or underfloor heating. They are highly efficient and environmentally friendly.

3. Water-Source Heat Pumps (WSHP)

Water-source heat pumps use the same principle as air-to-air heat pumps, but transfer heat to a hydronic heating system (radiant floor heating or baseboard radiators) or for domestic hot water heating.

4. Hybrid Heat Pumps: Combining Technologies for Efficiency

Hybrid heat pumps, also known as dual-fuel furnaces, consist of an electric heat pump and a gas furnace. You get the best of both worlds with these.

Choosing the Right Heat Pump for Your Home

You should consider several factors when buying a heat pump, including the region you live and the size of your home.

Assessing Your Climate and Region

While all heat pumps provide ample heating and cooling, not all models can withstand extreme temperatures, especially during winter.

The Northeast Energy Efficiency Partnerships (NEEP) has released a database of various heat pump models that can withstand the winter cold. You’ll find multiple models with varying ranges in temperature limits, making them perfect for below-zero climates. 

Additionally, you should look for a variable-speed compressor in heat pumps. This component helps the system switch and adapt to changing temperatures, which is especially beneficial for homeowners living in regions with varying climates.

Sizing Your Heat Pump

Many sizes are available on the market, but unfortunately not all will fit your heating and cooling needs. Oversizing leads to a waste of resources, while undersizing puts too much stress on the pump. Factors to consider include: 

  • Your home’s layout
  • Number and location of windows
  • Home insulation
  • SEER Rating
  • Flow Rates

Calculating Heat Load and Heat Loss

You can get the correct heat pump size by calculating the heat load and loss

The rule of thumb for heat load is that 1 sq. ft. of living space equals 30 BTU heating output. Measure your home’s total square feet, then multiply it by 30. 

Heat loss calculations use more complex formulas. It involves measuring various areas of your home and using a program to find out the heat loss of each room. An HVAC professional will be able to do these calculations for you.

Energy Efficiency and Environmental Impact

Environmentalists favour heat pumps over furnaces due to their efficiency and reliance on renewable sources for heating and cooling. 

Advantages of Heat Pumps in Reducing Energy Consumption

Heat transfer is much more efficient than burning fossil fuels to create heat. Air-source heat pumps deliver three times more heat energy to your home than the electricity it uses. You’ll get the results you want while your system works less. 

Additionally, heat pumps also function as air conditioners by pulling heat from your home and expelling it outside. As such, opting for a heat pump at home can help you conserve energy while simultaneously lowering your utility bills. 

Lowering Carbon Footprint with Heat Pump Technology

These heating and cooling systems produce little to no greenhouse gas emissions! Switching to heat pumps may reduce single-family home emissions by 142 million metric tons annually. 

Comparing Energy Efficiency Ratings: COP and SEER

The two must-know energy efficiency ratings for heat pumps are COP and SEER

COP stands for Coefficient of Performance and measures the heating efficiency of a system by dividing the heat produced by the energy used. A high number means less energy consumption, so look for the highest possible rating when buying a heat pump.

On the other hand, SEER stands for Seasonal Energy Efficiency Ratio and measures a heat pump’s cooling performance. This rating’s calculation involves dividing the total cooling output of the season (BTUs/hour) by the total energy consumption during a period (watts/hour). A high SEER value is better as it denotes less energy consumption.
