When putting our CH and HW on, it’s sometimes a lottery as to whether the central heating will come on. The HW works every time with no problems. Furthermore, when the CH does come on, sometimes only half of the radiators in the house come on - when this happens, we switch CH/HW off and switch on again immediately and the radiators that we’re not on then start to heat up. Very confusing and frustrating. Any ideas as to what the problem might be? Wondering if a service might fix the issue, or do we need a heating engineer?
