As the government cannot decide if it is punched, bored , countersunk or just cross threaded, I took a management decision and had a new boiler fitted. The old one one running well but the plastic components inside were beginning to crack crack up (parts that support the control board and electronics) it was 17 Y/o.
Replaced with a Bosch 8000 Life /hydrogen ready-if it ever happens.
Just need to get my head around all the new settings/ computer controls😖😱 .
With the builders putting gas into new builds nearby I dont think gas is off the menu YET.🤣
