Restore Dependable Heating and Keep Every Part of Your System Working As It Should.
Haggart Plumbers repair central heating systems across Edinburgh, from a single cold radiator or noisy boiler to a system that has stopped heating the home.

Complete Central Heating Repair Services
We diagnose and repair faults throughout wet central heating systems, including circulation pumps, motorised valves, expansion vessels, automatic air vents and system controls. We also clear airlocks, remove magnetite sludge, rebalance circulation and top up inhibitor where required. We commonly find that the visible symptom does not identify the actual fault. A noisy boiler, for example, may result from restricted circulation elsewhere in the system rather than a defective boiler component.
Call us when the heating stops, rooms struggle to warm up, the system makes unusual noises or several emitters heat unevenly. These symptoms can come from trapped air, sludge, failing valves, low system pressure or a worn circulation pump. In older Edinburgh tenements, we often work with Victorian pipe routes and heating circuits altered by different owners over many years. We trace the system carefully before recommending a repair.
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 Cover
-
Heating fault diagnosis
We check the boiler, controls, pump, valves, pressure and circulation in a logical order. This allows us to identify the failed part instead of replacing components through guesswork.
-
Power flushing and system cleansing
We use controlled water flow and cleaning chemicals to loosen built-up debris inside the heating circuit. We assess the pipework and system condition first because a power flush does not suit every installation.
-
Magnetite sludge removal
Black magnetite sludge restricts water flow and can cause cold areas, noise and repeated circulation trouble. We remove contamination, clean accessible components and add inhibitor where the system requires it.
-
Pump and motorised valve repairs
A weak circulation pump may run without moving enough water. A seized zone valve can also prevent heat reaching part of the property. We test electrical operation and water flow before repairing or replacing the component.
-
Airlock removal and system balancing
Trapped air can interrupt circulation, particularly after draining or other heating work. We remove air, check pressure and adjust the system so that water reaches each part of the circuit more evenly.
-
Expansion vessel and air vent work
A discharged expansion vessel may cause pressure to rise and fall as the heating runs. We check the vessel charge, safety discharge and automatic air vents, then recharge or replace defective parts as agreed.

Common Heating Problems We Solve
-
Radiators are cold at the bottom
Cold lower sections often indicate settled magnetite sludge rather than trapped air. We check whether the problem affects one part of the circuit or the full system. If contamination is restricting circulation, we advise on an appropriate chemical cleanse or power flush.
-
Some rooms are warm while others stay cold
Uneven heating can result from poor balancing, a restricted pipe, trapped air, a weak pump or a valve fault. We check flow through the system before making adjustments. In Edinburgh tenements, long pipe runs and later alterations can make circulation faults less obvious.
-
There is no heating
We inspect the controls, boiler demand, system pressure, pump and motorised valves to locate the break in operation. A thermostat may appear to call for heat even when a valve motor or circulation component has failed. We explain the fault before starting the repair.
-
The heating bangs or kettles
Banging, rumbling and kettling can indicate restricted water flow, scale or sludge. We do not assume that noise means the boiler has failed. We inspect circulation, water condition and pump performance, as black heating water often points to corrosion debris within the system.

How We Handle Your Central Heating Repairs
-
Arriving and fault diagnosis
We arrive at your Edinburgh property and inspect your heating circuit. We check the system pressure, test the circulation pump and evaluate the water quality to pinpoint the exact cause of the failure.
-
Clear explanation and pricing
We explain exactly what is wrong with the system and what we need to do to fix it. We provide a clear cost for the repair work, ensuring you know exactly what to expect before we proceed with any fixes.
-
Carrying out the repair
We complete the necessary repairs, whether that involves swapping a seized zone valve, replacing a pump or flushing out heavy sludge. You deal with a single point of contact throughout the entire job, ensuring clear communication.
-
System testing and aftercare
We refill the system, bleed out any airlocks and fire up the heating to test the circulation. We check every part of the circuit gets hot, verify the system pressure is stable and leave your home clean and tidy.
Central Heating Repairs Questions
-
We quote according to the fault and the work required rather than publishing a figure that may not apply. The final cost can depend on diagnostic time, replacement parts, system access and whether cleaning or draining is needed. We explain the proposed work and quote per job before proceeding.
-
A suitably qualified plumbing and heating engineer can repair pumps, valves, pipework, circulation faults and other wet heating components. Gas appliances require a Gas Safe registered engineer. Haggart Plumbers is Gas Safe Registered, No. 936063.
-
Our working hours are 7am to 7pm, seven days a week. Attendance depends on existing bookings, the nature of the fault and access to any required parts. We confirm current availability when you contact us rather than promising a time we cannot meet.
-
We often find narrow pipe routes, long heating circuits, accumulated sludge and alterations completed at different times. These factors can reduce flow through part of the property. We trace the circuit and test circulation before deciding whether balancing, cleaning or component repair will help.
-
Black water usually indicates magnetite and internal corrosion, but it does not automatically mean a power flush is appropriate. We assess the water, pipework and system condition first. A chemical cleanse may suit some systems, while more severe contamination may require controlled power flushing.
-
Yes, subject to the condition and accessibility of the system. Edinburgh properties can contain Victorian circuits alongside newer pumps, boilers and controls. We check how these parts interact and take care when working with pipework that may not tolerate aggressive cleaning or sudden pressure changes.
-
Not automatically. We assess the actual fault, parts availability, condition and repair implications before advising you. A repair may remain practical, but repeated breakdowns or unavailable components can change that decision. We explain what we find without presenting replacement as the only option.
