We have a combi boiler. If the boiler is cold (ie no heating on) and we fully open the kitchen sink or bath hot taps the boiler immediately starts heating the water. However with the bathroom basin, if we try to open the tap fully the water spurts all over the bathroom which is a unacceptable because both you and floor are covered in water, so generally we end up with no hot water in the basin. Is it because the pipes leading up to the basin and the mixer tap are narrow? IWould replacing them make any difference?
