Warning Signs Your Central Heating System Has a Leak
Don’t ignore the early warning signs that could leave your Coleraine family without heat when you need it most:
Immediate Red Flags:
- Boiler losing pressure daily – you’re constantly topping up the system;
- Cold radiators – some rooms never get warm, even with heating on full;
- Visible water around boiler, pipes, or radiators;
- Damp patches on walls near heating pipes;
- Higher heating bills – system working harder due to lost water/pressure.
Subtle Signs Many Miss:
- Boiler cycling on/off frequently – struggling to maintain pressure;
- Uneven heating – some radiators hot, others lukewarm;
- Strange noises from boiler or pipes (gurgling, banging);
- Rust stains around pipe joints or radiator valves;
- Musty smells near heating pipes or in airing cupboards.
Why Central Heating Leaks Are Urgent
Unlike mains water leaks, heating system leaks affect your family’s daily comfort and can cause expensive boiler damage. Lost pressure forces your boiler to work harder, increasing wear and energy costs.
Safety Warning: If you smell gas or see water near electrical components, turn off your heating system immediately and call us on 028 8280 0120.

Why Central Heating Leaks Need Specialist Detection
Many homeowners book a boiler service when their heating develops problems, but this won’t solve leak issues. Central heating systems require specialist leak detection because they’re fundamentally different from mains water systems:
Pressurised System Complexity:
- Higher pressure than mains water – leaks can be harder to detect;
- Closed loop system – water circulates rather than flowing through;
- Multiple components – boiler, pump, expansion vessel, radiators, pipes;
- Mixed materials – copper, plastic, steel components with different failure rates.
Gas Safety Considerations:
- System isolation must be done safely to prevent gas leaks;
- Boiler connections involve gas and water systems;
- Pressure testing requires understanding of heating system operation;
- Safety devices (pressure relief valves, expansion vessels) need proper handling.
Why General Plumbers Often Struggle:
- Heating-specific knowledge needed for system diagnosis;
- Specialised equipment required for pressurised system testing;
- Component interaction understanding – how leaks affect overall performance;
- Optimisation skills – restoring peak heating efficiency after repairs.
PCLA's Heating System Expertise:
- Gas Safe registered for all heating system work;
- Oil and gas experience – common systems across Northern Ireland;
- System optimisation – we restore peak performance, not just stop leaks;
- Complete service – detection, repair, testing, and performance verification.
The Difference This Makes:
We don’t just patch leaks – we understand how your heating system works as a whole and ensure repairs restore optimal comfort and efficiency for your Coleraine home.
How We Find and Fix Central Heating Leaks Safely
Our Gas Safe approach ensures your heating system is diagnosed and repaired safely, with full performance restoration:
1. Safe System Assessment
- Gas safety check – ensure safe working conditions;

- Thermal imaging – trace heating water paths and identify leak points;
- Pressure differential testing – isolate problem areas in complex systems;
- Tracer gas testing – for the most challenging hidden heating leaks.
3. Professional Repair Process
- Quality materials – appropriate for heating system pressures and temperatures;
- Proper installation – following Gas Safe standards for heating work;
- System integration – ensuring repairs work with existing components;
- Pressure testing – verify repairs can handle full system pressure.
4. Performance Optimisation
- System refilling with proper water treatment;
- Air bleeding – remove air locks from radiators and pipes;
- Pressure balancing – optimise flow to all radiators;
- Efficiency testing – ensure optimal heating performance.
5. Safety Verification
- Gas safety check – confirm all connections secure;

Common Central Heating Leak Locations in Coleraine Homes
Our experience across Coleraine properties shows heating leaks typically occur in predictable locations. Knowing these helps us detect problems quickly:
Behind Radiators (40% of heating leaks)
- Radiator valve connections – especially thermostatic radiator valves (TRVs);
- Pipe joints behind radiators where access is limited;
- Radiator bottom connections – often hidden by furniture;
- Wall-mounted radiator brackets – stress points that develop leaks.
Under Floors (30% of heating leaks)
- Pipe runs beneath floorboards, especially in older properties;
- Junction points where pipes change direction or join;
- Underfloor heating circuits – common in modern Coleraine developments;
- Pipe clips and supports – movement causes joint failures.
In Airing Cupboards and Utility Areas (20% of heating leaks)
- Boiler connections – flow and return pipes;
- Pump connections – high-pressure points prone to failure;
- Expansion vessel – pressure relief and connection points;
- Hot water cylinder connections in system boilers.
External and Garage Areas (10% of heating leaks)
- Boiler flue condensate – often mistaken for heating leaks;
- External pipe runs – exposed to weather and ground movement;
- Garage-mounted boilers – connection points and pipe work;
- Oil supply lines – specific to oil-fired heating systems.
Age-Related Patterns We See:
- 1960s-80s properties: Copper pipe corrosion, especially in concrete floors;
- 1990s-2000s properties: Plastic pipe joint failures, pump connections;
- Modern properties: Underfloor heating leaks, complex system components.
Seasonal Factors:
- Winter freeze damage – pipes expanding and contracting;
- Summer shutdown – seals drying out when heating not used;
- Autumn startup – problems discovered when heating first used.
Why Location Matters:
Understanding common leak locations helps us detect problems faster and advise homeowners on prevention. We know where to look first in different property types and ages.

FAQs About Central Heating Leak Detection in Coleraine
How do I know if my heating system has a leak or just needs a service?
If your boiler is losing pressure regularly (more than once a month), you likely have a leak. A service won’t fix leaks – you need specialist leak detection and repair.
Is it safe to keep using my heating if it's losing pressure?
Generally yes for short periods, but constantly low pressure can damage your boiler. If you see water near gas connections or smell gas, turn off the system immediately and call us.
Can you work on both oil and gas heating systems?
Yes, we’re experienced with both oil and gas systems common across Northern Ireland. Our Gas Safe registration covers all gas heating work.
How long does central heating leak detection take?
Most heating leaks can be located within 1-2 hours using our acoustic and thermal imaging equipment. Repairs are often completed the same day.
Will you restore my heating system performance after repairs?
Absolutely. We don’t just fix leaks – we refill, balance, and optimize your system so it works better than before the problem occurred.
