have not seen the Brass manifold anywhere on their website.
If we could get a hold of a brass manifold (or ask SWEP for an engineering
drawing or CAD model that they probably have) then we could do some proper
analysis or

I dont think the heatexchanger is unimportant.
I got the heater applications handbook from SWEPS website.
that is not related to whether or not the
heat was transferred.

The heat exchanger will not work as well when horizontal (the condensate
water will not drain out nicely and the steam will not pass in parallel
through all channels equally due to pressure gradient from top to bottom of
stack), but it will still work - just with greater pressure drop

I did not say that.

I was not suggesting that you actually repeat the analysis, or do something a

I dont understand your point.

Hmmm .. (Fakes hat on).
Just as well that the output flow was checked, even if only intermittently.
Otherwise (eg assuming the ecat was producing only hot water and no steam) one
could take the whole stack apart, drill and/or plug various ports, so that the
