What Is a Heat Pump System

Heat Pump Systems

If you are a homeowner and looking for options to heat and cool your home and reduce your energy bills, a heat pump system is a great option to consider. Heat pumps are very efficient and reliable heating and cooling systems and they can significantly reduce your energy costs. Heat pump systems are proven technology, capable of providing year-round comfort to homeowners in Canada by supplying heat in the winter and cooling in the summer.

Heat pumps are an excellent choice for heating and cooling new homes and retrofits of existing HVAC systems. They are also a great option when replacing an existing air conditioning systems.

What Is a Heat Pump and How a Heat Pump System Works?

Heat pumps have been around for decades and used both in Canada and globally to efficiently provide space heating and cooling, and in some cases, domestic hot water heating.

A heat pump system uses electricity to extract heat from a low temperature place (a source), and move the extracted heat into a higher temperature place (a sink). Like air conditioners, a heat pump system in cooling mode extracts thermal energy from your home spaces (source), resulting in drop of temperature and cooling of your home spaces. Similarly, as thermal energy is added to a sink, its temperature increases. In heating mode, the heat pump uses your home as a sink and thermal energy will be added resulting in an increase of temperature and heating the space. Heat pump systems are fully reversible and they can both heat and cool your home to provide year-round comfort.

Sources for Heat Pump Systems

Air and Ground are two common sources of thermal energy that are most commonly used for heating and cooling homes in Canada.

Air-Source Heat Pumps

Air-source heat pump are the most common type of heat pump systems in Canada. This type of heat pumps draw heat from outside air during the heating season and reject heat outside during the cooling season. During the heating season, air-source heat pumps reverse the process and absorb heat from outdoor and reject it inside your home to heat your home spaces. Even though the outdoor temperature is cold, there is a good amount of energy still available to be extracted and delivered to the building.

Mitsubishi Electric is a leading manufacturer of air source heat pumps which designed cold climate heat pump systems to operate in harsh winters of Canada. Mitsubishi Electric innovated VSCi (Variable Speed Compressor Inverter) Technology, which allows for constant heating or cooling at different temperatures in up to 8 rooms of your home, with one system providing more temperature control and resulting in saving energy bills.

Ground-Source Heat Pumps

Ground-source heat pumps also known as Geothermal Heat Pump Systems, use the ground water, the Earth or both as the source of thermal energy in the season and as reservoir to reject heat removed from the home in the cooling season.

Sinks for Heat Pump Systems

As mentioned earlier, sinks are where heat pump systems reject the absorbed thermal energy. The two common sinks for thermal energy commonly used for heat pumps are air and water.

Air – When air is used as a sink, the heat pump system transfer the thermal energy to air and deliver it to your home using a centrally ducted system or a ductless indoor unit such as wall-mounted, floor mounted, or ceiling cassette unit for heating or cooling of your home.

Water – In this type of heating, water will be heated by the heat pump system. The heated water then can be used to supply terminal systems such as radiators, radiant floor or a fan coil unit via hydronic system.

Benefits of Using a Heat Pump System

There are several benefits in using a heat pump instead of conventional heating and cooling methods.

Energy Efficiency and Lower Operating Costs

Furnaces and boilers provide space heating by heating air through the combustion of a fuel such as oil or natural gas. While the efficiency of furnaces and boilers are continuously improving, they still cannot reach 100% efficiency, because not all the available energy from combustion is used to heat the air. Heat pump systems operate differently, the electricity consumed by heat pumps are used to transfer thermal energy between two locations. Therefore heat pumps operate more efficiently and well over 100% and they produce more thermal energy than the amount of electricity they use.

Better Safety

Heat pumps are safer than combustion-based systems because they are relying on electricity and not combustion of fuel to generate heat. For this reason they come with fewer safety concerns compared to their counterparts.

They can provide cooling

During the warm season in Canada, heat pumps are able to reverse the process and act like air conditioning units.
