    P&ID for DHW with solar collector

    Hi. I have looked into many P&IDs, list of symbols etc. Haven't found what I was thinking of (maybe wrong, trivial, too basic, who knows [shadeshappy] ), besides I'm a little confused about some things. Well here it is the, kind of, P&ID of DHW production(please notice that I omitted many...

    Heat pump ?? in DHW production

    Hello. We say that heat pumps function with a ΔΤ of 5°. Let's say we want to heat fresh water entering our storage tank at 15°C (as it comes from the water main) to 54°C at a flow rate of 0,8m³/h (our secondary circuit). The primary circuit should have a ΔΤ of 5°. Roughly, by energy balance we...
