Our engineers explain things clearly, without jargon.
A combi boiler heats water as you use it, so there is no tank to run out. When the hot water fails, the fault is in the boiler itself or its controls.
A common cause is the diverter valve. It switches the boiler between heating and hot water. If it sticks, you may get hot radiators but cold taps, or the other way round. Our boiler engineer in Darlington can explain what has happened and what the repair involves.
Lukewarm water, or water that runs hot and then cold, can point to a faulty sensor or low water flow. Low pressure can also stop a combi heating water.
Before you book, check the pressure gauge and the hot water setting on the boiler. Try a different tap too, as the problem may be with one tap only.
Combi boilers also need a good flow of water from the mains. If several taps run at once, the water may cool. That is normal, but a sudden change is worth checking.
A combi that heats the radiators but not the taps may also have a faulty sensor. Your engineer will test the valve, the pump and the sensors to find the cause.
Keep your boiler manual somewhere easy to find. It lists the right pressure, the reset steps and what each code means.

Our answers below cover the questions people ask most about boiler repairs in Darlington. Still have a question? Our boiler FAQ page may help.
Phone the National Gas Emergency number, 0800 111 999, right away. Don't use the boiler, light switches or anything with a flame. Open the doors and windows to let air in. If you can reach the meter safely, turn the gas off there, then wait outside for the engineer.
Defrost the pipe with warm water, then reset the boiler. A hot water bottle or a warm cloth wrapped round the pipe also works. Don't use boiling water. If the pipe keeps freezing each winter, it may need lagging or rerouting, which our engineers can sort out.
