I have recently moved into a 11 year old 4 bedroom detached house with a Ferolli Combi. The CH works OK, but when I turn on a hot domestic tap, the water runs cold for about 15 seconds (as expected) runs hot for 10 secs then cold again for another 15 secs before the hot runs constantly. Why the cold/hot/cold/hot sequence? I have noticed that the boiler takes 10 secs to ignite after the hot tap has been fully opened .......is this normal?.......shouldn't it be instantaneous?..........can I adjust the timing?
Cheers all
