Complete Central Heating Repairs Services
We repair central heating faults affecting circulation, pressure, temperature and system control. Our work includes tracing intermittent faults, replacing failed pumps or motorised valves, clearing airlocks, recharging expansion vessels and cleaning sludge from system water. We commonly check whether the boiler receives a demand for heat before testing the pump, valves and circulation. This avoids replacing parts without finding the underlying cause.
Call us when the heating stops, takes too long to warm the property or behaves differently between rooms or zones. Banging noises, repeated pressure changes and black system water can also point to circulation or contamination problems. In East Lothian, we often assess long pipe runs in larger rural properties because weak circulation can affect the furthest parts of the system first. We inspect the complete heating circuit, explain what has failed and quote for the work required.
Where the fault is the boiler itself we carry out boiler repairs, and for pressure loss with no obvious cause we use leak detection.

What Central Heating Repairs Covers
-
Heating fault diagnosis
We test the heating demand, controls, pressure, pump operation and water circulation in a logical order. This allows us to separate an electrical control fault from a hydraulic problem or failed component before recommending a repair.
-
Circulation pump repair or replacement
A sticking, noisy or failed circulation pump can leave the system running without moving enough heated water. We check the electrical supply, pump settings and system resistance before repairing or replacing the unit.
-
Zone valve and motorised valve repair
Motorised valves direct heated water to the correct circuit. We inspect the valve body, actuator and microswitch to identify whether the head can be replaced or the complete valve needs attention.
-
Expansion vessel and air vent work
Pressure that rises sharply or drops after the system cools can indicate an expansion vessel problem. We test the vessel charge and inspect automatic air vents for leaks, blockages or failed seals.
-
Airlock removal and system rebalancing
Trapped air and uneven flow can prevent heat from moving through the complete circuit. We remove air, confirm pump operation and rebalance the system so each section receives an appropriate share of the flow.
-
System cleansing and sludge removal
We use chemical cleaning or power flushing where testing confirms magnetite sludge or contaminated water. We flush loosened debris from the circuit, refill the system and add inhibitor to help protect internal components.

Common Heating Problems We Solve
-
Radiators are cold at the bottom
Cold lower sections often indicate restricted water movement caused by magnetite sludge. We check more than one heat emitter, inspect the system water and assess circulation before advising whether chemical cleaning or a power flush is appropriate.
-
Some rooms heat up while others stay cold
Uneven heating can come from trapped air, poor balancing, a weak pump or a valve that no longer opens fully. We test the wider circuit instead of assuming every affected room has the same fault. Long heating runs in rural East Lothian properties may need careful balancing after the repair.
-
The heating is on but the house stays cold
If the boiler appears to run without warming the property, we check flow temperature, pump operation, valve positions and circulation. We also confirm that the controls send the correct demand. These checks show whether heat is being produced but failing to move around the system.
-
The system bangs or produces black water
Banging, kettling sounds and dirty black water can indicate scale, sludge or poor circulation. East Lothian properties can experience scaling alongside magnetite contamination. We inspect the water condition and operating temperatures before deciding whether targeted component work, chemical cleaning or full system cleansing is needed.

How We Handle Your Central Heating Repairs
-
Fault reporting and scheduling
You contact our team to describe the symptoms your heating system displays. We listen to the issue and arrange a suitable time for an engineer to visit your East Lothian property. You deal with a single point of contact from your very first call.
-
On-site diagnosis
Our Gas Safe Registered engineer arrives and inspects the boiler, pipework, and controls. We test electrical components, check water flow, and assess system pressure to identify the exact point of failure. We explain the fault clearly before starting any physical repair work.
-
Component repair or replacement
We carry out the necessary fix using high-quality replacement parts. Whether we are swapping out a seized circulation pump, freeing a stuck zone valve, or clearing a stubborn airlock, we work carefully to ensure a lasting repair that protects the rest of your heating system.
-
Testing and system handover
Once the repair is complete, we refill the system, bleed all air, and fire up the boiler. We check that heat distributes evenly across the property and confirm the system operates safely. We leave your home tidy and provide advice on how to keep your heating running efficiently.
Central Heating Repairs Questions
-
Yes, provided the plumber has the correct heating and gas qualifications for the work involved. We repair pumps, valves, pressure components, circulation faults and contaminated systems. When the work involves gas appliances, our Gas Safe registration covers the required checks.
-
We quote each repair by the job because cost depends on the fault, access, replacement parts and whether the system needs cleaning. We diagnose the problem first and explain the required work rather than giving an unsupported figure before inspection.
-
Some component faults can be diagnosed and repaired during one visit when the correct part is available. Sludge removal, intermittent faults and larger systems can take longer. We explain the likely timescale after testing the system and identifying the cause.
-
We take bookings from 7am to 7pm, seven days a week. Availability depends on existing work and the type of fault. Call us with the symptoms, property details and any error information so we can plan the visit properly.
-
Call Haggart Plumbers on 01620 843000 to arrange a heating repair in East Lothian. We will ask what the system is doing, when the fault started and whether you still have any heating or hot water.
-
They can. Larger rural properties may have long pipe runs, several heating zones or parts of the system far from the pump. We check circulation and temperature changes across the complete circuit because faults may show most clearly at its furthest points.
-
Scale can affect heat transfer and contribute to noise or restricted operation in some systems. We also check for magnetite sludge, which has a different cause. Testing the water and circulation helps us choose the correct cleaning or repair method.
-
No. Age alone does not prove that replacement is necessary. We identify whether the fault comes from the boiler, controls, pump, valves or circulation. We then explain whether repair remains practical based on condition, parts availability and the work required.
