How long does a boiler installation take? +
A straightforward like-for-like combi boiler replacement typically takes one day — around 6 to 8 hours. If the boiler is being relocated, the flue route changed, or you are converting from a conventional system, the job can take 2 to 3 days. Your engineer should give you a clear timeline before starting and ensure you have hot water by the end of the final day.
How do I know if my boiler needs replacing rather than repairing? +
If your boiler is over 10 to 15 years old, breaks down frequently, or has an efficiency rating below A (90%+), replacement is usually more cost-effective than repeated repairs. A single repair costing over £400 on an older boiler is often not worthwhile. Modern condensing boilers are up to 30% more efficient than older models, so a new boiler can pay for itself through lower gas bills within 5 to 7 years.
Which boiler brands do your engineers in Ahoghill work on? +
Our boiler engineers in Ahoghill work on all major brands including Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann, Glow-worm, and Potterton. Many are manufacturer-approved installers, meaning they can offer extended warranties on new installations. If you have a less common boiler brand, let us know and we will match you with an engineer who has experience with your specific model.
My boiler keeps losing pressure — is this an emergency? +
A boiler that loses pressure gradually over weeks usually has a small leak somewhere in the system — often a radiator valve or a pipe joint. This is not an immediate emergency but needs investigating. If the pressure drops rapidly or the boiler is cutting out repeatedly, call an engineer promptly. You can repressurise the boiler using the filling loop as a temporary fix, but this does not solve the underlying problem.
What are the signs of carbon monoxide from a boiler? +
Warning signs include a yellow or orange boiler flame instead of blue, dark staining around the boiler, increased condensation on windows, and a pilot light that frequently goes out. Symptoms of carbon monoxide exposure include headaches, dizziness, nausea and confusion. If you suspect a carbon monoxide leak, open windows, leave the property immediately and call the Gas Emergency Service on 0800 111 999. Fit a CO alarm near your boiler — they cost under £20 and save lives.
