    Since seeing the other thread, I have just thought to ask.

    In the kitchen, if the hot tap isn't opened up fully, once the hot water starts coming through it will make a racket! Loud banging noises through the pipes and the hot water splutters, if I fully open the tap the noises goes away and it runs fine. Is this 'water hammer' or something else?

    I can't remember if the same thing happens in the bathroom.

    What are your best recommendations?

    Thanks

    A fairly new combi boiler, the previous occupents had central heating put in the house - I suspect it was storage heaters previously.

    Never heard the term "water hammer" before, but you could have some air stuck in the system. Try on the scewfix forum for advice, they're normally really helpful. But a system drain should do the trick. But I ain't no boiler engineer if it breaks and floods your house.:D

    A few years ago I had the same problem with my bath taps. The plumber put a thicker washer on, and that solved the problem.

    Sounds like the water is heating up too much too quickly, like kettling I guess, is it pretty hot when it's spluttering ?

    With the tap full on you have a lot more water passing the heat exchanger so, it's not getting so hot so quickly, no kettling, no sputtering.

    Could try turning down the hot water thermostat on the boiler and see if it makes any difference...

    :)
