Hi - I have a pump which seems to work for HW only! I say this because I have (please don't laugh) recorded the sound of it using a mic and analysed the sound wave using a sound studio software.
The waveform of the pump when HW only is called is a regular sine-type wave indicating a 'pulse' or pump if you will (the hertz of the thing ??). The waveform of the pump on CH only is pretty much flatline.
I know this is an unorthodox way to test a pump but it begs the question - is it possible for the pump to work ok for HW only? If the CH water circuit is blcked would that not also affect the capcity to generate hot water, or are they on two separate water pipe circuits?
