dunsley neutraliser

[Jcrabb]

hi there everyone
has anyone out there had experience with a dunsley neutralizer?
i got called out to a fairly large house with a wood burner and a heat only gas boiler, both going into the neutralizer at the cylinder. each boiler seems to have a pump on the return.
the fill goes into the wood burner which i thought was strange.
anyway the initial problem was that there was no heat in the rads in the extension.
all the pipework that i can see is in 15 so thats not great. after balancing i have got heat in there but nothing spectacular.
just wondering if the neutralizer could have anything to do with it and also, why does the cold feed go all the way to the wood burner.
any advice please?
cheers and happy new year!

properly set up the neutraliser sould provede heat to ch with no issues.

re cold feed to wood burner, prehaps the installer felt better doing it that way? dont no the answer to that one
