Your boiler is one of the most important appliances in your home. It keeps your radiators warm, your showers hot, and your family comfortable all year round. But like any piece of equipment, boilers don’t last forever.
The trouble is, many people only think about replacing their boiler after it has broken down completely – often in the middle of winter when you need it most. At Eazy Heat, we believe prevention is better than cure. By learning the early warning signs of boiler trouble, you can plan ahead, save money, and avoid being left in the cold.
How long should a boiler last?
Most modern boilers will last between 10–15 years if serviced regularly. Some well-maintained boilers can run even longer. However, once your boiler reaches this age, it’s usually less efficient and more prone to issues.
Tip: If your boiler is over a decade old and repairs are becoming frequent, it may be time to consider a replacement.
1. Frequent Boiler Breakdowns
If you’re calling out an engineer more than once a year, you’re probably spending more on repairs than you would on a new boiler. Even when the fault is fixed, there’s no guarantee another part won’t fail soon after.
With a new boiler from Eazy Heat, you’ll enjoy 12 years of parts and labour warranty – giving you long-term security and saving you the headache of repeated repair bills.
2. Rising Energy Bills Despite Normal Use
Noticed your heating bills going up, even though your usage hasn’t changed? This could be your boiler’s efficiency slipping.
- Older boilers often operate at only 60–70% efficiency
- Modern A-rated boilers run at 90%+ efficiency
- Upgrading could save you up to £300 per year on energy bills
That’s money better spent elsewhere – and a greener choice for the planet.
3. Radiators Take Ages to Warm Up
When you get home and turn the heating on, you expect results fast. If your radiators take forever to heat up – or don’t quite reach the warmth you’d like – your boiler may be struggling.
While sludge in the system or trapped air can cause slow heating (and may be fixed by a flush or service), it’s often a sign that the boiler itself is past its best.
4. Strange Noises From the Boiler or Radiators
All boilers make some noise, but you shouldn’t hear banging, gurgling, kettling or loud vibrations. These sounds can indicate limescale build-up, worn components, or pressure problems.
If noises become regular or more intense, it’s usually a warning sign that your boiler is on its way out.
5. Leaks or Funny Smells
Water leaks around the boiler shouldn’t be ignored. They can cause electrical faults, corrosion, and even structural damage to your home.
Even more serious is a sulphur-like or eggy smell. This can indicate a gas leak or carbon monoxide issue. In this case:
- Turn your boiler off immediately
- Call the National Gas Emergency Service on 0800 111 999
- Speak to a Gas Safe registered engineer
If your boiler is leaking gas or water, replacement is often the safest and most cost-effective solution.
6. Your Boiler Flame Burns Yellow or Red
The flame in a gas boiler should always burn bright blue. If it looks yellow or red, it may not be burning fuel properly – which can produce dangerous carbon monoxide. Don’t ignore this warning. Contact a Gas Safe engineer right away.
7. Spare Parts Are Hard to Find
For older boilers, spare parts can become rare or discontinued. This means even minor repairs can be expensive or impossible. Installing a modern boiler ensures you’ll have access to affordable parts for years to come.
What are the benefits of replacing an old boiler?
Upgrading your boiler doesn’t just prevent breakdowns – it can also:
- Save money on heating bills
- Improve your home’s comfort and warmth
- Lower your carbon footprint
- Add value to your property
- Give you peace of mind with long warranties
At Eazy Heat, every boiler we install comes with an industry-leading 12-year warranty and is fitted by our team of Gas Safe registered engineers.
FAQs: Boiler Replacement Questions People Ask
How do I know if my boiler is beyond repair?
If your boiler needs repairing more than once a year, is leaking, making strange noises, or your engineer tells you parts are hard to source, it’s usually time to replace it.
Is it cheaper to repair or replace a boiler?
Repairs can fix short-term problems, but repeated call-outs add up quickly. A new boiler is an investment that pays for itself in lower bills, reliability, and warranty coverage.
Can a boiler last 20 years?
Yes, some boilers can last this long with perfect maintenance. However, they’re unlikely to remain efficient, and parts become harder to find.

Prices vary depending on the boiler type and your property, but at Eazy Heat you can get a fully installed replacement from around £1,700 including VAT. Use our online quotation tool to get an accurate price in just two minutes.
