Central Heating Repair in Edinburgh
When your central heating is not working properly, your home becomes uncomfortable fast — especially during a Edinburgh winter. Cold radiators, uneven heating, strange noises from the system, and thermostats that do not respond are all signs that something needs attention. OnCall Home Repairs connects you with qualified heating engineers in Edinburgh who diagnose and repair central heating faults efficiently. From individual radiator problems to full system diagnostics, we will match you with the right engineer for the job.
What Goes Wrong with Central Heating Systems
A central heating system is made up of many interconnected components: the boiler, a network of pipes, radiators, a pump, motorised valves, a thermostat, and a programmer or timer. A fault in any one of these can affect how the whole system performs. Cold radiators might be caused by trapped air, a blocked valve, sludge build-up, or a failing circulation pump. A system that takes a long time to warm up could have a pump running at the wrong speed, a partially blocked pipe, or a boiler that is not firing correctly.
Some heating problems develop gradually. You might notice that one radiator is always colder than the others, or that the system makes banging and clanking noises when it fires up. These are often signs of sludge and corrosion building up inside the system — a mixture of rust, limescale, and debris that settles in radiators and pipe runs, restricting water flow and reducing efficiency. Left untreated, this sludge can eventually damage the boiler itself, leading to far more expensive repairs.
The heating engineers in our network are experienced in diagnosing all types of central heating faults. They can bleed radiators, replace thermostatic radiator valves (TRVs), swap out failed pumps and motorised valves, and recommend a power flush if your system is clogged with sludge. For older systems that have reached the end of their useful life, they can also advise on whether a full system upgrade would be more cost-effective than repeated repairs.
How Central Heating Repair Works
Describe the Heating Problem
Call 0333 240 8428 and tell us what is happening with your heating. Which rooms are cold? Are all radiators affected or just some? Is the boiler running but nothing is getting warm? These details help us identify the likely area of the fault.
Engineer Inspects the System
Your matched engineer visits your property and carries out a thorough inspection of the heating system — checking the boiler, pump, valves, thermostat, and individual radiators to locate the source of the problem.
Fault Diagnosed and Explained
Once the fault is identified, your engineer explains what has gone wrong and what needs to be done to fix it. You receive a clear quote for the repair. No work goes ahead without your agreement.
Repair Carried Out
The engineer completes the repair — whether that is replacing a valve, fitting a new pump, bleeding the system, or carrying out a more involved fix. They test the full system afterwards to make sure every radiator is heating up properly and the controls are responding correctly.
