A boiler that keeps losing pressure almost always points to a leak or a failed expansion vessel. Here's how to narrow down the cause and what to do next.
A boiler that won't fire up is usually a gas-supply, ignition or condensate issue. Here's the order to check things in — and when to stop and call an engineer.
When the radiators are hot but the tap runs cold, the fault is almost always in the hot-water side of a combi — usually the diverter valve or the plate heat exchanger.
A leaking boiler ranges from a harmless PRV drip outside to a corroded heat exchanger. Here's how to tell which you have and what to do before the engineer arrives.
A boiler that rumbles like a boiling kettle is 'kettling' — usually scale or sludge trapping heat in the exchanger. It shortens boiler life if ignored.
Repressurising a combi boiler is a 2-minute homeowner job. Here's exactly how, what pressure to aim for, and the one moment to stop and call an engineer.
A few faults are safe homeowner jobs — repressurising a low-pressure boiler, thawing a frozen condensate pipe, and bleeding a radiator. Anything involving gas, ignition, the flue or the sealed water-side of the boiler must be done by a Gas Safe registered engineer. Our articles make clear which is which.
