I am shortly going to convert my conventional open vented DHW cylinder into a Heat Bank following the design given at
I have a very good supply from the rising main. It runs at ~8bar (reduced to 5bar by a pressure reducing valve at entry into the house) and delivers 30l/min at 8bar.
When additional outlets ae opened, will the secondary output temperature will drop as the flow rate through the PHE increases? Or perhaps it won't... perhaps the flow rate to each outlet will drop... and the temp will stay the same...?
Basically what I don't quite understand is the dynamics between water pressure, flow rate and number of outlets open.
Many thanks in advance for any info on this.
Mike
