If the gas furnace’s pilot light keeps going out, it may be due to a weak flame, faulty thermocouple or problem with the pilot orifice or gas regulator
Humming boiler noises can be created if water arrives from the mains at too high a pressure. This can cause valves in the boiler or around a home’s pipes to hum. A humming noise can also be caused by a pump sending heated water around the pipework too quickly, or by the bearings in the boiler fan humming as it moves.
This issue can be caused by anything from faulty motorised valves, broken system diaphragms and airlocks, to low pressure or a broken thermostat. To determine whether this issue is caused by low pressure, you should check your pressure gauge to see if it is below 1.
A boiler leaking water is usually a sign that a seal or a valve has developed a fault. However, if the problem is left untreated, a leaking boiler can cause other components to erode as well as cause damage to the electrical components within the boiler.
The most common reasons for a boiler to lose pressure are: Releasing air or water from a radiator when bleeding it. A leak from the appliance or on the system most commonly from radiator valves or system components.
If you’re experiencing cold radiators even though your boiler is working normally, it’s likely that there’s a problem with your boiler pump or central heating controls.
There are several things that could have caused the overheating, such as a loss of coolant through a ruptured hose, a punctured radiator, a defective thermostat, a defective radiator cooling fan, or a blown cylinder head gasket.
Possibly interference. Other smart technologies can potentially interrupt the signal and prevent it reaching the boiler. Smart TVs, routers and other devices can potentially prevent it from connecting. Reposition the thermostat so there are none of these kinds of items between the boiler and the thermostat.
As the condensate pipe lies outside the house it can freeze when the temperature drops. The water flowing through the pipe freezes, blocking the release of residual water from the boiler.
The most common cause of a short cycling boiler is having an oversized unit for the home you are trying to heat. If your boiler is too powerful for the demand your home puts on it, then you’ll likely notice it firing up and turning off frequently.
