Items on hand are a good reason!
Yes I did get the curves message on the graf, but still wondered where the Panaflo would fall along the curve.
Just speaking for myself, I'd go for the strong performance. But very VERY glad to find a way, as Cathar is indicating, to have high performane at very modest noise. Not the MOST extreme performance perhaps, but very good. For myself and my use anyway.
Which leads to my next question. Does anyone know of a US heater core that compares well with the ones that Cathar has posted? I'm sorry to say I don't. Most US cores are thicker for one thing, and many of the newer & thinner ones are alum.
50-60$ while more than we pay for cores here Cathar is worth it for the much better configuration of the core when compared to any I know of here. You do very nice work on making up those rads to Cathar, very nice.
