Peter, Mats Lewan measured the output water temperature at two points in time
and it was quite low. Review his report. What evidence do you have that the
heat exchanger did not transfer the heat?
I did not say that.
Of course it transferred the heat. This is proven. But it was filled
with condensate.
The primary outflow was surprisingly low in temperature, so it must have
transferred all heat that was available in this unfortunate configuration.
I have not seen an example in the SWEP handbook that exposed so good
performance under normal operation conditions.
Therefore there was not hot steam, but hot water and the actual
secondary delta_t was much lower than measured..
