the boiler isn't firing up…..?
Check the pressure gauge & pilot light.
Combi-boiler (instant hot water & heating from same boiler) - check that the pressure gauge is between 1 and 1.5.
If the pressure is below 1, then fill the central heating system with more water to bring up the pressure. Opening the tap or valve on the flexible loop pipe below the boiler usually does this. You will hear the water rushing into the central heating pipe. Close the tap after a few seconds & re-check the gauge.
Older boiler model - check that the pilot light is still lit.
If not, follow the instructions on the boiler flap to re-start the pilot light. Be patient as it can take a few attempts to be successful.
