My point has also always been that if you are going to vent the exhaust - why waste the extra money on a platinum catalyst?
Do you mean on any (window-vented etc.) catalytic heater, or are you just referring to the platcat with its power vent...
I am referring to the PlatCat with the power vent and have mentioned it by name several times.
The primary benefit of a catalytic heater over a blue flame is that the off gas from the catalyst is less noxious. If the exhaust is vented outside, there is no benefit to the catalyst. Thus a vented catalytic heater like the PlatCat is just a waste of money.
You could vent a blue flame heater which would be substantially less expensive to purchase with the same results as the PlatCat. Which is essentially what the original furnace is - a vented blue flame heater.
