I'm getting hydrogen build up in a radiator on my CH system (when I bleed it it burns strongly, looks like hydrogen from O level chemistry to me). It's only in one radiator but it fills the top 2 or 3 inches of the rad every couple of months.
Any ideas how this is happening, and how to fix it? Otherwise system works fine, and no changes to CH or elec. recently
