Understanding Heat Pump Lifespan: How Long Do Heat Pumps Last?

Are you curious about how long a heat pump will last before you need to replace it? Understanding its lifespan is essential for planning maintenance, budgeting for future expenses, and ensuring your home stays comfortable year-round. 

In this guide, we’ll discuss the factors that influence the longevity of heat pumps, the typical lifespans you can expect, and tips for maximising your system’s performance and durability. 

Ready to get the most out of your heat pump investment? Let’s explore how long heat pumps really last and what you can do to extend their lifespan.

How long does a heat pump last?

An air-source heat pump can last 10 to 20 years, with modern versions having longer lifespans. Ground-source heat pumps have a longer lifespan, typically lasting between 15 and 50 years. 

Depending on the model you choose and how it’s used, some might remain functional for over 100 years. 

The heat pump revolution 

The UK is seriously behind the curve when it comes to heat pump installations. 

Scandinavian countries have embraced the technology, with Norway, Finland and Sweden paving the way for lower energy bills and a healthier environment (Carbon Brief). 

Businesses and households across the UK are becoming increasingly interested in heat pumps, with three installation options available: 

1. Air-Source Heat Pumps: Available for households and apartments of all sizes, ASHPs are usually installed on the rear or side of a property. Their versatility and accessibility make air-source pumps the most popular option. 
2. Ground-Source Heat Pumps: These heat pumps use underground pipes to transport heat collected from the earth and transfer it into energy. You’ll need a lot of outdoor space or be willing to pay extra for a vertical GSHP system. 
3. Water-Source Heat Pumps: If you live near a water source, such as a pond, river, or lake, you can install a water-source heat pump. 

All three heat pump options can save money in the long term and lead to energy independence. 

If you live in a standard home or apartment, you’re probably leaning towards air-source heat pumps, which are more convenient to install. However, they’re also susceptible to damage. 

Next, we’ll reveal what might impact your heat pump’s lifespan. 

Which factors impact heat pump lifespans?

Numerous factors might impact your heat pump’s longevity. Understanding each can help you protect your investment and ensure the pump continues to provide seamless power. 

Environmental factors 

Ground and water-source heat pumps typically have longer lifespans because they’re not exposed to the elements. In contrast, air-source heat pumps deal with a lot of rain, wind, sunshine and snow, which makes them more susceptible to damage. 

While older heat pumps were more prone to failure, modern versions can withstand more wear and tear, enhancing their longevity. 

Operating conditions 

Modern heat pumps are designed to withstand the elements and maintain consistent performance, even in colder weather. However, air-source heat pumps will have to work harder in the winter seasons, as less heat is available from the air. 

A lack of insulation can also compromise your pump’s lifespan because the property will lose heat quickly. Addressing insulation issues before the installation can keep your heat pump consistent. 

Quality 

As the saying goes, if it seems too good to be true, it usually is. Sure, you can find plenty of cheap heat pumps around – but will they perform properly? The answer is probably no. The quality of your heat pump and interior unit is integral to its performance. 

Opting for a reputable heat pump provider ensures you’re investing in quality. You’ll pay more initially, but the long-term savings will be worth it. 

Installation 

Installation is another key component in heat pump longevity. In recent years, the number of complaints about heat pumps not performing has increased, leading some people to believe that they’re not a wise investment. 

Trying to install the heat pump alone or not choosing certified technicians means you’re spending money on a pump that might not work. In contrast, professional heat pump installation services will ensure your home benefits from seamless energy production. 

Maintenance 

Just like your boiler requires ongoing maintenance, heat pumps should undergo regular checks. While you can perform these inspections alone, professionals can assess the heat pump’s components and ensure they’re in full working order. 

The electrical system, refrigerant levels, and outdoor unit can all suffer damage, but annual servicing identifies any issues and prevents expensive repairs or replacements later on. 

Top tips for getting the most out of your heat pump

As the interest in heat pumps grows, more UK properties will benefit from their efficiency. If you’re exploring heat pumps, it’s important to follow these tips: 

• Choose Wisely: Select the right heat pump for your budget, property type, and long-term needs. If you have a large garden, consider ground-source heat pumps (GSHPs). Yes, they’re more expensive, but they are the most consistent solution. 
• Research Your Provider: Heat pump installation services should have MCS or other relevant certifications, which show they know how to install renewable energy solutions safely. 
• Know Your Limits: Heat pumps are available in different sizes, and selecting the correct one for your property’s size and needs ensures longevity. Opting for a larger heat pump means it won’t need to work overtime, protecting it from damage. 
• Remember Maintenance: Ensuring your heat pump receives regular inspections and maintenance is crucial in preserving its longevity. Minor repairs are easy, but replacing your heat pump can cost thousands. 
• Prepare Your Property: Evaluating your building and identifying where heat escapes can ensure your pump works effectively. 

The bottom line 

Investing in a heat pump today means moving towards a greener tomorrow. No heat pump is invincible, but neither are boilers or solar panels. Ensuring proper installation and ongoing maintenance will give you a reliable energy supply for years.
