Heating System Repairs Across County Sligo

When your central heating stops working properly, the effects are felt in every room of the house. Cold bedrooms, lukewarm radiators, a heating system that runs constantly but never quite warms the place - these are daily realities for too many homeowners across County Sligo, particularly in the colder months when the Atlantic climate makes reliable heating essential rather than optional.

Heating problems are rarely straightforward. A cold radiator might be caused by trapped air, a failed valve, sludge in the system, or a circulation pump on its last legs. Getting to the root cause requires a systematic approach and an understanding of how every component in your central heating system works together. That is exactly what our qualified heating engineers provide.

What We Offer

Our heating repair service covers every component of your central heating system, from the boiler to the individual radiators and everything in between:

• Radiator repairs and replacement - We fix or replace leaking radiators, seized valves, and radiators that are not heating properly. If your radiators have cold spots at the bottom, this typically indicates sludge build-up that needs addressing.
• Circulation pump repair - The pump is the heart of your heating system. If it fails or weakens, some or all of your radiators will not heat up properly. We diagnose pump faults and replace them when necessary.
• Thermostat and controls - Faulty thermostats, programmers, and zone valves can leave you with no control over your heating. We repair and replace all types of heating controls, including upgrading to modern programmable or smart thermostats.
• System balancing - If some radiators get very hot while others remain cold, your system is unbalanced. We adjust the lockshield valves throughout the house to ensure even heat distribution.
• Pipework repairs - Leaking joints, corroded pipes, and air locks in the pipework are diagnosed and repaired.
• Expansion vessel and pressure issues - Loss of system pressure, frequent need to repressurise, and waterlogged expansion vessels are common faults that we resolve.

Common Heating Problems in Sligo Homes

The type of heating issues we encounter varies considerably depending on the age and type of property. Sligo Town has a mix of Victorian terraces, mid-century estates, and modern developments, each with their own characteristic heating systems and problems.

Older properties (pre-1980s) often have heating systems that have been modified and extended over the years without a complete redesign. The result is a system with dead legs, poorly sized pipes, and an assortment of different radiator types that was never properly balanced. These systems benefit enormously from a professional assessment and rebalancing.

Rural properties across Ballymote, Tubbercurry, and the broader county often have oil-fired heating systems that work hard during Sligo’s long, cold winters. The combination of heavy use and sometimes older infrastructure means pumps, valves, and controls wear out and need replacing.

Modern homes typically have more efficient systems, but they are not immune to problems. Sealed heating systems can lose pressure due to microscopic leaks, expansion vessels fail, and modern electronic controls can develop faults.

When to Call a Professional

Some heating issues can be resolved with simple steps - bleeding a single radiator that has an air lock, for example, or checking that the timer is set correctly. But there are situations where you need a qualified heating engineer. If you are wondering why your radiators are not heating up properly, our guide on why are my radiators not heating up covers the common causes and solutions. Call us if:

• Multiple cold radiators - If more than one radiator is cold or lukewarm, the problem is systemic and needs professional diagnosis
• No heating at all - If the boiler fires up but the radiators stay cold, there may be a pump failure, valve fault, or major air lock
• Persistent pressure loss - If you need to repressurise your heating system more than once or twice a year, there is a leak that needs finding
• Unusual noises - Banging, gurgling, or whistling from pipes or radiators indicates air, sludge, or mechanical issues
• Uneven heating - Some rooms boiling while others are freezing is a classic sign of an unbalanced system
• High fuel bills - If your heating costs have increased without a change in usage, your system is losing efficiency

Improving Your Heating Efficiency

Beyond repairs, there are several improvements that can make a meaningful difference to how well your heating system performs and how much fuel it uses:

• Thermostatic radiator valves (TRVs) allow you to set different temperatures in different rooms, rather than heating the entire house to the same level
• A programmable thermostat lets you schedule heating to come on only when you need it, rather than running all day
• System balancing ensures the boiler is not working harder than necessary to heat the furthest radiators
• Power flushing removes sludge and debris that reduce heat transfer and force the boiler to work harder
• Pipe insulation in unheated spaces like the attic prevents heat loss before the water even reaches the radiators

We are always happy to advise on the most cost-effective improvements for your specific system. Sometimes a small investment in better controls or a system flush can make a dramatic difference to comfort and running costs.
