Murphy's Law states: "Whatever can go wrong will go wrong, and at the worst possible time".
It is how most accidents happen. "A chain is only as strong as its weakest link" in another truism. Both these sayings can be applied to many wood pellet boilers in use in Ireland.
I have already discussed Back-Burn dangers in the previous couple of blogs. A back burn can happen in any boiler with an automated fuel feed system. There needs to be elaborate and fail safe methods for dealing with a back burn. There is only a very primitive system in many Irish installations.
I ask again - how many fires will it take for SEI to set the standards higher?
