3 Check the Pressure
Another common issue with gas boilers is low pressure Low pressure can cause the boiler to not heat water properly or produce hot water at a reduced flow rate You can check the pressure gauge on the boiler to see if it is within the recommended range If the pressure is too low, you can try to increase it following the manufacturer’s instructions If the pressure is too high, you may need to bleed the radiators to reduce it.
4 Bleed the Radiators
Air trapped in the radiators can cause blockages and prevent hot water from circulating properly To bleed the radiators, you will need a radiator key and a cloth to catch any water that may leak out repair gas boiler. Turn off the boiler and wait for it to cool down before starting the bleeding process Starting from the lowest radiator, insert the radiator key into the bleed valve and turn it anti-clockwise until you hear a hissing sound Wait until water starts to come out and then close the valve Repeat this process for all radiators in the house.
