Intermitent hot water problem on Combi?
I have an oil fired Worcester Combi. Intermitently the hot water will only work when the flow is decreased )turning down the tap on the bath). This varies from not having to at all- to having to turn it virtually off. The water pressure to the house is good and constant, the pressure in the system is correct and this does not occur on the kitchen tap where the flow is naturally reduced
