ive got no hot water at all unless i switch the heating on then it heats up,if i switch the heating off water goes cold again,
heard it may be the diaphram,where is it located and is it easy to change
hi shaun it depends which model of vokera you have as nearly all of the earlier vokera boiler models prior to 1990 have diaphragms to allow the hot water to function independently of the heating system what model have you got ?
