Thanks Tony, yes it is warm enough. I will have to call someone out but to have it working reasonably in the meantime is fantastic so thanks very much.
Hi, My Volkera Excell 80E gas boiler is not working though the green 'on' light is on. when you turn on the hot water nothing happens and the radiators are coldHowever there are no diagnostic red LED lights on. Any suggestions of what I can try before I call someone out? Many thanks,
