Thanks for your reply Hot water is set to come on at 6am. That’s when it’s worst when there no heat in the system at all. Would it be worth draining system and refill??????
My boiler has started making bubbling or jingling noise in the pipes. This only happens when hot water is being called for. Central heating is fine. The boiler is below a bedroom and it sounds 10 times worse upstairs. Obviously air in there somewhere. Any ideas much appreciated. Thanks Phil
