Combi, system or conventional boiler — which do I need? +
A combi boiler heats water on demand and is ideal for smaller homes with one bathroom — no tank or cylinder needed. A system boiler uses a hot water cylinder and suits homes with two or more bathrooms where demand is higher. Conventional (regular) boilers have both a cylinder and header tanks and are found in older properties. Your engineer will recommend the right type based on your home's size and hot water demand.
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.
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.
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.
Which boiler brands do your engineers in Bristol work on? +
Our boiler engineers in Bristol work on all major brands including Worcester Bosch, Vaillant, Baxi, Ideal, Viessmann, Glow-worm, and Potterton.
