The exchanger did work in the horizontal position. All it has to do is to
condense and cool the vapor/water mixture that enters into the primary. The
temperature of the exiting liquid was low enough and that is proof that the
device transferred the heat.
The temperature of the exiting liquid was not measured.
The temperature of the secondary out pipe was measured too close to the
steam/hot water inlet.
The heatexchanger was horizontal and therefore had no condensate
drainage. I must fill up with condensate.
It could not produce more than 2° delta_t in this situation, because the
primary delta_t was 80° and the primary/secondary water flow ratio was
1:40. So it is proven, that the secondary delta_t measurement was wrong
due to wrong thermoelement placement.
