Hot water supply to radiators is ok.
Hot water supply to kitchen and bathroom taps keep running hot and cold, can't take a good shower due to cold spots in hot water flow.
If someone could advise me on how to rectify problem with not to much expense I would be very grateful.
Boiler is ten years old, is now the time to change to new condensing boiler.
Thankyou.

Thanks for your answer Lee, much obliged.

i think the 280 has a calorifier for the hot water and from what your suggesting going hot and cold sounds like it could be scaled or sludged up. it can be fixed, parts expensive also time consuming to exchange
