Hello just wondering weather someone can shed any light as to why my boiler will run for hours then the flame goes out and it wont light again until its been sat for an hour or so and its the same with the hot water when its been run it wont light again until its been sat for an hour without any demand , The fan and pump keeps running but it will not ignite so you have to take the demand off it for about an hour then it will relite on either heating or hot water or heating then swop over to hot water but then flame goes out was fitted new when we built the house but not used for 2 years then when we moved in started playing up 6 months later ,Any guidense would be greatly apreciated ,john
