Another one for you boiler people..... the boiler was firing up and running for 30-40 seconds before cutting out, it sounded like it was kettling so i had a fiddle with rads and pump speeds until it gurgled and burped. reset all rads and pump speed to original settings and now its running fine.......But when it switches off when satisfied, there is a dripping noise in the boiler at the top. it sounds like its dripping every second or so and landing on hot metal and sizzling. this goes on for about a minute then stops.when it fires up and it carries on working as normal???
