Has you boiler been serviced recently? If not we would recommend that it is.
If you have a condensing boiler a lot of manufactures (i.e Vaillant) strongly recommend that the combustion chamber seal is changed every 5 years. If the combustion chamber seal perishes it can cause a lot of damage to the boiler and would also be dangerous.
