Thanks folks . Ill have a look at it. I do realise that this is a DIY site and thus implies a level of willingness and self belief to be able to have a go myself. I suppose I thought it may be a simple / stupid thing Id missed. But many thanks
Hello. The hot water function on my Potterton Performa 28 has stopped working. The main dial is set to central heating and hot water. The central heating works fine , but very luke warm water . All lights are on except the hot water light ( as one would imagine) . Can anyone help please ?
