Richard, I have a Linea 24, and this is exactly the problem I have. Despite several under maintenance "repairs - bodges - scratching of heads" etc, no so called engineer has been able to fix my Vokera. I now have no hot water at the taps, but radiators which will heat the house perfectly, even in the Summer, when the control is set to 17 degs. One final point, does the preessure on your boiler soar to over 3 BAR when the rads are turned on.
