Honestly one of the biggest misconceptions we hear is that using a heat pump in cooling uses too much power - this couldn't be further from the truth!
They actually cost less to run in cooling mode than in heating mode, and we'll tell you why.
A heat pump doesn’t actually generate heat like a traditional heater; it simply moves heat from one place to another. In cooling mode, it extracts heat from inside your home and releases it outside. In heating mode, it works in reverse—pulling heat from the outdoor air and transferring it inside to warm your home.
Heat Is Easier to Remove Than to Extract
When your heat pump is in cooling mode, it’s working with warm indoor air, which has plenty of heat to remove. In contrast, during winter, the heat pump must extract heat from cold outdoor air, which is more challenging and requires more energy.
Smaller Temperature Differences in Summer
In summer, the temperature difference between indoors and outdoors is typically smaller than in winter. For example, if it’s 30°C outside and you want your home at 22°C, the heat pump only has to remove a small amount of heat. But in winter, if it’s 5°C outside and you want your home at 22°C, the heat pump has to work harder to find and transfer enough heat.
Defrost Cycles Increase Winter Energy Use
When outdoor temperatures drop, frost can form on the heat pump’s outdoor coil, reducing efficiency. To combat this, the system enters a defrost cycle, temporarily reversing operation to melt the ice. This process requires extra energy, increasing overall heating costs.
How to Maximise Efficiency Year-Round
To keep your heat pump running efficiently in both heating and cooling modes, follow these simple tips:
Keep Filters Clean: Dirty filters restrict airflow and reduce efficiency.
Ensure Proper Insulation: A well-insulated home reduces the demand on your heat pump.
Schedule Regular Maintenance: Professional servicing keeps your system running smoothly and efficiently (we can help with that).
