Central Heating Repair in Co. Cork
13 businesses offering central heating repair across Co. Cork.
A heating system that has stopped heating properly rarely announces which part failed, and the pattern of what is cold says more than the boiler does. Radiators cold at the top and warm at the bottom just need bleeding, because air collects at the highest point. Cold at the bottom is the opposite complaint: something has settled where water should be moving. One cold room while the rest of the house is fine points at that radiator, its valves or the balancing of the system. Everything cold at once points instead at the boiler, the pump, a zone valve or the controls, and those are four very different repairs.
Most of what shortens the life of an Irish heating system sits in the pipework rather than in the boiler. Water standing in steel radiators produces magnetite, a black iron oxide sludge that drops to the bottom of radiators, chokes narrow heat exchanger passages and wears out pump bearings. A power flush or a chemical clean shifts it. A magnetic filter on the return catches what forms afterwards and an inhibitor slows the reaction down, which is why an engineer who cleans a system and fits nothing to keep it clean has done half a job.
Where the work stops being plumbing matters. Anything on the gas side of a natural gas or LPG boiler must be done by an installer on the Register of Gas Installers of Ireland, and putting heating controls on a new circuit is restricted electrical work requiring a Safe Electric registered contractor. Radiators, valves, pumps and pipework carry no such restriction. Cost follows how many radiators are involved, whether the system is being cleaned or partly replaced, how buried the pipework is, and whether zoning is added.

Common questions
Why is one radiator cold when the rest of the house is hot?
If it is cold at the top only, air has collected in it and bleeding will fix it. If it is cold at the bottom with a warm top, sludge has settled inside and the radiator needs flushing or replacing. If the whole radiator stays cold, suspect the valves, including a thermostatic head that has seized, or a system that has never been balanced so the nearest radiators take all the flow.
Do I actually need a power flush?
It is worth doing where there is real evidence of sludge, such as radiators cold at the bottom, black water when you bleed them, a pump that keeps failing or a boiler that short cycles. It is not a routine service item and it will not fix a fault that has nothing to do with circulation. Ask what the engineer found before agreeing to one, and ask what is being fitted afterwards to keep the system clean.
Can a plumber repair my heating, or does it have to be an RGI installer?
Radiators, valves, pumps, pipework and bleeding are ordinary plumbing and are not restricted. The moment the work touches the gas side of a natural gas or LPG boiler, it must be carried out by an installer on the Register of Gas Installers of Ireland, which is a legal requirement rather than a preference. Oil boilers sit outside that scheme, and OFTEC registration is the usual equivalent to look for.
My boiler pressure keeps dropping. What does that mean?
A sealed system that loses pressure is losing water somewhere, either through a leak on the pipework or radiators, or through the pressure relief valve discharging outside. Topping it up repeatedly treats the symptom and lets a small leak keep soaking a floor or ceiling. It is worth having the cause traced rather than adding water every few weeks.
