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 secondary outlet is a mixture of X*

Did you see in the specs that the heat exchanger should be mounted vertically when used for phase change. Having it horizontal should reduce effectiveness and err in Rossi's favour On Sat, Dec 10, 2011 at 3:58 PM, Horace Heffner wrote: > The heat exchanger is Swedish, make and model: SWEP E8T-SC-

With the 1:40 primary:secondary flows there's most likely not a problem. And any problems (steam not condensed) would give a lower calculated power (as pointed out, in Rossi's -- ie less likely fake-- favour.) - Original Message - > It should be tested, if this exchanger can handle the c

The key is the brass manifold - the heat exchanger is unimportant. But I 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 te

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 and inconsist
