Go greener with an air source heat pump from Hive
Heat pumps are becoming an increasingly popular choice for people in the UK looking for a low-cost, stable and eco-friendly heating solution.
Air source heat pumps are built to last, typically serving homeowners for 15 to 20 years. Some well-maintained systems can last the two-decade mark, surpassing traditional gas boilers, which usually last 10-15 years. However, it's important to note that various factors can influence a heat pump's lifespan. Regular maintenance, proper installation, and environmental conditions all play essential roles in determining how long your heat pump is going to keep your home cosy and warm for.

What factors impact a heat pump's lifespan?
But what exactly can impact your heat pumps life expectancy? This comes down to several factors that you should be made aware of:
Environmental factors
The environment where your heat pump operates has a significant impact on its longevity. In fact, air quality, humidity levels, and the presence of corrosive elements can all affect your system. Coastal areas, for instance, may expose heat pumps to salt air, potentially accelerating corrosion if not properly protected, while urban areas with higher pollution levels might require more frequent filter changes to maintain efficiency. That said, if you are looking at installing a heat pump and you live in a coastal area, there are protective coatings available to increase longevity.
Weather conditions
Extreme weather conditions can put additional stress on your heat pump. In areas with harsh winters, the system may need to work harder, potentially shortening its lifespan if not properly sized for the climate. Similarly, regions with very hot summers can strain the cooling function of reversible heat pumps. As such, proper sizing and installation for your specific climate is fundamental for heat pump longevity.
Brand quality
Not all heat pumps are created equal. Higher quality manufacturers, like Hive’s partnered brands, often use more durable components and have better engineering, which can translate to a longer lifespan. While premium brands might have a higher upfront cost, they often prove more cost-effective in the long run due to their durability and efficiency.
Installation
Proper installation is critical to your heat pump's performance and longevity. A system that's incorrectly sized for your home or improperly installed can lead to increased wear and tear, reducing its lifespan. Always choose a MCS accredited, experienced installer to ensure your heat pump is set up for success from day one.
Maintenance
But above all, regular maintenance is perhaps the most important factor in extending your heat pump's life. Routine check-ups, cleaning, and timely repairs can prevent small issues from becoming major problems. Neglecting an annual check-up has the potential to decrease efficiency, higher energy bills, and a shortened lifespan for your system.
What maintenance does a heat pump need to extend its life?
To keep your heat pump running smoothly, you must ensure that you’re staying on top of the maintenance. This includes annual professional servicing, where a technician will check refrigerant levels, clean coils, and ensure all components are functioning correctly.
As a homeowner, you can even contribute by keeping the outdoor unit clear of debris, regularly changing or cleaning filters (usually every 1-3 months), and ensuring good airflow around both indoor and outdoor units.
We also recommend monitoring your system's performance. If you notice any unusual noises, decreased heating or cooling efficiency, or higher energy bills, it's best to have a professional check your system. As a general rule, make sure to address the smallest of issues promptly to prevent more significant issues down the line.
Will running my heat pump constantly affect its lifespan?
Contrary to what you might think, running your heat pump consistently at a steady temperature is often better for its lifespan than frequent on-off cycles. Heat pumps are designed for continuous operation and work most efficiently when maintaining a consistent temperature. Dramatic temperature swings can put more stress on the system.
However, this doesn't mean you should run your heat pump at full capacity all the time. Using a smart thermostat to maintain comfortable temperatures efficiently and setting back temperatures slightly when you're away or asleep, can help optimise your system's performance and lifespan.
Can I extend the life of my heat pump?
Absolutely! With proper care, you can potentially extend your heat pump's life beyond its expected lifespan. Some simple, but effective strategies include:
- Scheduling regular professional maintenance
- Keeping the system clean and free from debris
- Using a smart thermostat to avoid overworking the system
- Addressing any issues promptly
- Ensuring proper insulation in your home to reduce strain on the heat pump
Remember, a well-maintained heat pump not only lasts longer but also operates more efficiently, saving you money on energy bills throughout its lifetime.
How do I know if my heat pump needs replacing?
Although there are some great methods to extend the life of your heat pump, there will come a time where your heat pumps life has come to an end and it's time for a replacement. You’ll know when this day has come by the following signs:
- Age: If your system is approaching or exceeding 15-20 years, replacement might be more cost-effective than continued repairs.
- Frequent repairs: If you're calling for repairs more than once or twice a year, it might be time for a new system.
- Inefficiency: Rising energy bills despite regular maintenance can signal decreasing efficiency.
- Inconsistent temperatures: If your home has hot and cold spots, your heat pump might be struggling to distribute heat evenly.
- Unusual noises or odours: These can indicate serious issues that might warrant replacement.
If you're experiencing any of these signs, consult with a professional to determine whether repair or replacement is the best option.
Is it easy to replace a heat pump?
Replacing a heat pump is a job for professionals, but the process is generally straightforward for experienced installers. That said, the size and complexity of the job can depend on factors like:
- Whether you're switching to a different type or size of system
- The condition of your existing ductwork or radiators
- Any necessary upgrades to your home's electrical system
A professional installer will assess your home, remove the old system, and install the new one, typically within a day or two. They'll also ensure the new system is properly sized for your home and climate, which is necessary for efficiency and longevity.
