I have a Woster Bosch 28CDi combi bolier and i have found that in my kitchen it takes some time for the hot water to come through. I have been told it might be the 'heat exchnage' due to lime scale build up parts about £180-£200 + fitting is this right.

Is it worth fitting a anti lime scale device would this cure my problem the cheaper way?

Any help must appreciated

Thanks :roll:
