Over the last few days there has been a strong smell of white spirit(ish) coming from the two radiators in my kitchen. They were installed around 10/11 months ago, haven't recently been bled and haven't been painted. They haven't smelled like this before. I haven't put any corrosive inhibitor in the system and I moved in nearly 4 years ago.
Does anyone have any idea on what could be causing it and what I can do to fix it?
