Heating engineers in Belfast
Cold radiators, noisy systems, new radiators or a full rebuild. Tell us the job and we pass it to heating engineers covering Belfast.
Belfast heating systems are more varied than most UK cities. Alongside gas and oil boilers, 4.9% of households have two or more types of central heating, such as an oil boiler alongside a stove with a back boiler. A heating engineer needs to understand how they connect.
Belfast at a glance
- Water hardness
- Varies by supply zone. NI Water's postcode checker gives 43 mg/l as calcium carbonate (soft) in Belfast Ballyhanwood, 67 mg/l (moderately soft) in Belfast Breda South, and about 158 mg/l (moderately hard) in Belfast Oldpark and Dunore Belfast North. The water comes from Lough Neagh, Silent Valley and Dorisland reservoirs in different blends. Source
- How homes are heated
- 70.9% of Belfast households heat with mains gas only and 20.2% (30,190 homes) with oil only. 2.4% use electricity only and 4.9% have two or more types of central heating. Source
Cold radiators
Radiators cold at the top need bleeding, which you can do with our guide to bleeding a radiator. Radiators cold at the bottom usually have sludge, which needs a flush.
In Belfast's harder water zones in the north and west of the city, open-vented systems can also gather scale. Ask for inhibitor to be added after any flush.
Mixed systems
Systems that link a stove's back boiler with an oil or gas boiler need correct controls and safety devices. If you're adding or removing a stove, get a heating engineer to redesign the system rather than just cap the pipes.
Moving from oil to gas
When a home converts, the radiators and pipework can usually stay. The engineer should flush the system, fit a magnetic filter and set up controls for the new boiler. It's also a good time to replace any undersized or failing radiators.
Small jobs with a big effect
Thermostatic radiator valves on every radiator except the one in the thermostat's room, a balanced system and a lower boiler flow temperature all cut fuel use without new equipment. In an oil-heated home, where every litre is paid for up front, these changes show quickly in how often you need a delivery.
If you're planning a heat pump later, ask for any replacement radiators to be sized for a lower flow temperature.
Belfast homes and what they need
Victorian and Edwardian red-brick terraces
Return rooms at the back are often the coldest part of the house. A larger radiator or better insulation there helps more than turning up the thermostat.
Suburban semis
Many semis have systems that were extended over the years. Balancing the radiators so they all heat evenly is a cheap, effective job.
Apartments in the city centre and riverside
Some blocks use communal heating. Faults in the central plant are for the building manager, while your radiators and valves are your responsibility.
Areas covered
Engineers who cover Belfast work across areas including Ormeau, Stranmillis, Malone, Ballyhackamore, Sydenham, Andersonstown, Newtownabbey, Holywood, Dundonald and Carryduff.
Questions people in Belfast ask
How long does a power flush take in Belfast?
Usually a day for a typical house. The engineer should show you that the water is running clear before finishing.
Can a heating engineer work on oil systems?
On radiators and pipework, yes. Work on the oil boiler itself needs an OFTEC registered technician.
Can I get help paying for heating repairs in Belfast?
The Affordable Warmth Scheme can fund heating improvements for eligible owner-occupiers and private tenants on lower incomes. Contact NI Energy Advice on 0800 111 4455 to check.
