So still no heating, and no quick fix either.
The boiler man came out today, lovely chap he was. Spent 15 minutes looking at boiler before calling me down.
The flue has been incorrectly fitted, so doesn't fit to the top of the boiler right, meaning you can see daylight from it. This means combustable gasses can leak into the utility room, including carbon dioxide if the boiler went wrong (which it isn't working at present remember). As the original workmen have tried to bend the flue piping to fit the top of the boiler, the flue pipe has bent all the top of the boiler in too. And the piping has been fitted with ordinary wood screws, not the right type!
So it is a complete sham.
The boiler man who came has capped it all off and issued an immediately dangerous notice. He now has to complete a RIDDOR report and send it to the HSE who will contact us shortly.
DH has now contacted the builders - we are obviously outside out product warranty but as it is so dandgerous and theyare at fault the buck lies with them. Once HSE know and Corgi they could be in serious trouble, so they had better sort it!
Builders have just this minute called me back (whilst half way through typing this) and the site manager will be with me within 30-60 minutes apparently.
This has reminded me to go and buy a carbon dioxide monitor too, to have near the boiler - just in case.
