How important is it to install a magnetic boiler filter when replacing a boiler?

I only do it on older sys that are very dirty or when I suspect oxygen ingression. It's magnetic so it only deals with ferrous debris. However, non magnetic debris may fall out of the flow stream in a dirt collector.
I flush older sys 3 times when replace a boiler and sometimes use a chemical, too.
'hot_rod' would be the one who could give information that's trustworthy.0 -

Why not?
All hydronic system have oxygen ingress. So it depends on how much O2 ingress and how much ferrous metals you have in the system.
Non barrier pex is the worse for O2 ingress buy all pex allows some O2 in.
Turns out the systems with small amounts of ferrous metals can breakdown faster. The old cast boiler, steel piping systems can be less prone to magnetite concerns.
I'd invest in a good dirt separator with a magnetic function, you get the best of both critical functions.Bob "hot rod" Rohr

I have a follow up question regarding the Caleffi hydro separator. Will the base model separator provide sufficient air removal or will I need to add a micro bubble air removal device as well. I know there is the Sep-4 option that does both micro bubble and magnetic dirt removal.0

Do you mean the 548 series? It does have the coalescing media for excellent air and dirt, but no magnet.Bob "hot rod" Rohr

Thank you for getting back to me. I had planned on the an 1 1/4" 548 series but was not sure if it had coalescing media and if it would eliminate air as well as a dedicated Discal or Spirovent.0

Yes it has a stainless mesh from top to bottom.Bob "hot rod" Rohr

Here is a sample after a typical Dirtmag flush.0

Would you install the filter such as the dirtmag in the primary loop or the secondary loop if you have a low-loss header?0
