Why the boiler is not firing up?
Low Thermostat: The boiler may not fire up if the thermostat is set too low. Your heating system won’t start until the temperature of the environment is below the temperature set on the boiler. Increasing the thermostat will solve this problem. Sometimes, the boiler is not firing up because of an electrical fault.
How do you reignite a pilot light on a boiler?
How do you relight the pilot light on a boiler?

If the engineer finds any other faults with the water heater, it might be more cost-effective to get a new one. The pilot light is the tiny flame inside the boiler that ignites the gas, which then consequently heats the water. When it goes out, there is no hot water and no heating.
What happens if boiler pressure is too low?
Should the boiler pressure be too low (below 1 bar), then the boiler will fail to work, while high boiler pressure (over 2 bar), can put unnecessary strain on the boiler and could lead to it breaking down.
What causes the pilot light on a boiler to go out?
