Hi, I have been running a solid fuel/gas fired system via a Dunsley neutraliser for a few years. My gas boiler is now on borrowed time so I am thinking of replacing it. My old gas boiler is pumped on the return so it pulls the water from the neutralising vessel. I have noticed that modern condensing boilers require to be pumped on the flow side.
Does this mean the new boilers are not suitable for my system ?
Thank you,
