A faulty boiler can be stressful—especially when it starts acting up during colder months or fails to deliver hot water when you need it most. But when your boiler starts causing problems, one of the most common questions we get at EMD Plumbing & Heating in Derry is:
“Should I repair or replace it?”
Here’s a guide to help you decide what’s best for your home and your budget.
- How Old Is Your Boiler?
Most boilers last between 10 to 15 years with regular servicing. If yours is older than that, it’s likely less efficient, more prone to breakdowns, and could be costing you more in energy bills. In this case, a replacement might be the most cost-effective option in the long run.
- Frequent Breakdowns
If you’re calling out an engineer more than once a year, those repair bills can quickly add up. Constant issues often signal a boiler that’s nearing the end of its lifespan. Instead of patching it up repeatedly, investing in a new, reliable model could save you stress and money.
- Rising Energy Bills
Older boilers are far less efficient than modern ones. If your energy bills keep rising and you haven’t changed your usage habits, your boiler could be the culprit. Upgrading to an A-rated energy-efficient boiler can reduce your energy consumption by up to 30%, making it a smart long-term investment.
- Availability of Parts
For older or discontinued models, replacement parts can be hard to find and expensive. If your boiler requires a rare or obsolete component, replacing the whole unit might be a more practical (and faster) solution.
- Repair Costs vs Replacement
As a general rule:
• If the repair costs are less than half the price of a new boiler and your system is under 8–10 years old, a repair could be the right move.
• But if the costs are stacking up, or your boiler is old and inefficient, a replacement may offer better value.
- Is Your Boiler Still Safe?
If your boiler is showing signs of dangerous faults (like carbon monoxide leaks or pilot light issues), don’t take the risk. Safety should always come first. Have it inspected by a qualified Gas Safe engineer immediately.
