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.
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 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.
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.
