Hi
I have my remodeled kitchen with full underfloor access below. I have installed ultrafin with pex 2 1/2 inches below the subfloor as recommended.
My problem is my Old 80% Boiler with one zone and cast iron radiators throughout for my 2000 s/f home. I have tried a tie in to one "Return" leg from a radiator to the new pex (for the lower temp of the return) but for some reason, the water is not getting through this new connection. The pex just does not get hot. I have purged air from the pex and from the cast iron too, but still the hot water does not get through the pex.
I know this is not an idea set up. Can anyone suggest a better solution here without buying a new furnace? I am open to a set up that would heat exchange from a hot water tank, but could use some diagrams and parts list to get it done.
Thanks in advance.
Doug
