I was called out to an oil installation (14 months old) with a boiler house model in the centre of the house (these houses used to have warm air units) and the boiler had sooted up (cracked nozzle holder!!)
The installation was grant aided, and had been audited when finished and again after the installer had carried out remedial actions
a) the boiler was conventional flued in a compartment in with 2 vents (hi/low) into different living spaces, neither of which had purpose provided ventilation!
b) the boiler had a single walled flue
c) there was 1.5m of flexi-flue liner from the 1m of twin wall coming off the boiler
d) the remote acting fire valve phial was under the boiler
e) the condensate & prv were piped side by side to an 'unviewable' position, no tundish
f) the bypass valve was 6 inches from the boiler (doesn't have over run anyway so don't see the point)
the list goes on........
Queried the customer to how the audit went, and the installer had been made come back and fit an EXTERNAL type tiger loop and the tank was (marginally...6inches) higher
than the bottom of the oil tank!!!
Second audit went without a hitch!
I have removed the tiger loop and went back to a single pipe supply!
Where are they getting the auditors?
