Hi,
I've been looking for some info on how to correctly read pump graphs. Information seems to be a bit difficult to find.
Anybody with knowhow can give me some details how to read the following chart?
(Pump is fixed on stage 1 by setting d19)
The residual pump discharge height depending on the by-pass valve is shown in Fig. 3.10.1 (ecoTEC plus) and 3.10.2 (ecoTEC plus 637 / 837).
When running at 20 kW (Max, set on d0) the difference between flow and return is reported (d40/41) as 14 degrees. This translates to roughly 1220 litres of water heated (by 14 degrees) per hour. Correct?
So this is what the pump pushes around. Now how to interpret the graph.
Am I correct is saying that in that case the resistance of the system is around 150 mbar, or 1.5 meter of head?
