Heat pumps are highly energy efficient devices, consuming roughly 50 percent less electricity compared to electric heating systems such as baseboard heaters or electric furnaces. This efficiency stems from the fact that heat pumps do not generate thermal energy but rather transfer it from one place to another. Today’s heat pumps often feature snazzy variable-speed or dual-speed motors in their fans, both indoor and outdoor. These motors make sure the airflow stays comfy, reducing chilly drafts and saving energy. And there have been other tech upgrades that make your home more comfortable and lower your energy bills.

The government of Ontario has partnered with Enbridge, offering up to $7,100 in rebates. Enbridge recognizes the importance of energy conservation and environmental stewardship. By advocating for the adoption of heat pumps, they are encouraging individuals and businesses to embrace sustainable heating solutions that reduce their carbon footprint and contribute to a greener and more efficient energy landscape!

Heat Pump Cooling Mode

The fundamental operation of a heat pump revolves around manipulating the pressure and temperature of the refrigerant to absorb heat in one location and release it in another. In the cooling mode, the refrigerant enters the compressor in the heat pump, where it is condensed into a liquid and its temperature increases. From there, the liquid refrigerant moves to the condenser coil, transferring heat to the condenser coils. A fan blows air over the coils, cooling the refrigerant.

The cooled liquid refrigerant then flows indoors to an expansion valve. As the pressure decreases, the refrigerant vaporizes and cools significantly. The cold, vaporized refrigerant passes through the indoor coils. As it travels through the evaporator coil, it absorbs heat from the air. The blower then circulates the cooled air throughout the room. Heat pumps are adept at managing humidity as moisture condenses on the cool evaporator coils.

During this process, the refrigerant absorbs thermal energy and transforms into a gas.The refrigerant returns to the compressor outside, and the cycle begins anew.

Heat Pumps Heating Mode
A heat pump equipped for heating includes a reversing valve, which reverses the process and refrigerant flow during the heating mode. In the heating mode, the indoor evaporator coil functions as the condenser, while the outdoor condenser coil becomes the evaporator. Outside, the refrigerant within the evaporator absorbs heat from the air, and then it travels to the compressor to be pressurized. The refrigerant then moves indoors to the condenser coil, where it releases heat, and the warm air is blown into the space. The cycle then repeats.
