How Heat Pumps Work

How Does A Heat Pump work?

Heat pumps leverage coolants and electricity to transfer heat from one location to another. This equipment can provide you with an ideal temperature all year round. The heat pump produces heat energy by extracting heat from the outside air or groundwater and transmitting it to the refrigeration coolant. Following this, the coolant undergoes compression, which induces a drastic increase in the temperature. Next, the coolant is moved to the heat pump’s indoor unit. This unit then lets the airflow over the hot coolant, which increases the temperature to align with the thermostat’s requirement for heat inside the home.

Essentially, the equipment comprises two main parts- the wall cassette and the condenser unit. The wall cassette is placed in the building, whereas the condenser unit is placed externally. Both the units form a connection via the refrigerant line.

The indoor wall cassette is managed using the thermostat to ensure the unit provides both cooling and heating functions. If the heat pump is used for heating, the pump will turn on the fan in the outdoor unit to initiate the air extraction process from the building’s exterior. The refrigerant line brings the heat to the indoor unit, which forwards the heat to the air inside the building using the fan inside the wall cassette. If the pump is used for cooling, the process is reversed, and the heat is transferred outside the building while cool air is invited in.

Why is Maintenance needed?

Like all other heating and cooling systems, maintenance is essential for the effective functioning of heat pumps. Carrying out routine maintenance ensures that the equipment works smoothly and provides improved energy consumption.  It also ensures regular clearing drains of unwanted bacteria or dirt so the integrity of your home and surroundings are kept intact.

Research shows that a well-maintained heat pump can conserve around 10% to 25% more energy than an abandoned pump. 

Regular maintenance also serves as a proactive approach to ensure the equipment remains protected from any additional damage. With routine maintenance, you can make sure all the systems are running smoothly. This can help determine and prevent any damage to the compressor and other components, thus saving costs in the long run. 

Essentially, carrying out routine services for your heat pump improves reliability and helps you circumvent all the unexpected and expensive repairs in the long run.
