Soldato
We’ve just had a boiler service (valiant ecotec 831 plus) and the engineer has said the burn starts with a poor ratio (think it’s was breaching 350 parts per million of co) but gradually comes down.
He’s advised that he thinks it’ll be due to a dirty chamber and will need a strip down and clean.
Any idea how much these usually cost?
