Hi all.
Last winter my old potterton netaheat developed some popping sounds when fired up. Reading through treads here I decided to add some sentinel X400 and left it for 4 weeks then drained, flushed and refilled adding sentinel X100.
The popping noise has now returned, and my question is will it do any harm to the system to add sentinel X400, (I just did yesterday) and leave it in longer or indefinatly?
Thanks.
