Ok in my house I have a heat pump which supplies simultaneous heating and cooling.

The chilled water loop is running at 7c I can change this temp up or down. I can stab into this loop and provide water at 7c to the pc. I can control the flow by use of a metering station.

What flow rates should I be looking for to the CPU block?

What condensation problems might I get?

Any help most appreciated.
 
What kind of heat pump is this? Is this a ground to water heat pump?
Just saying because 7°C seems very high for a heat pump?

Anyways, you could only really use a heat exchanger to cool the PC due to chemicals and antifreeze in the cooling fluid you would have a problem with corrosion in the PC water blocks. And the flow rate and pressure straight from a heat pump would be massive.
Heat exchangers are available but pipes on heat pumps tend to be very big, say 28+mm and you may struggle to find an exchanger of able to go from the 28+mm to 16mm and the hefty restriction to the fluid that this would cause although this may not be a problem due to the size of the pumps used.

Also another issue may be that your heat pump may not normally be on when you want your PC running?

200 - 400 lph will be adequate at that temp , dependoing on abient and case temp depends if u need to worry about condensation tbh im sure others will come up with diferent tho

but at a lower temp u can get away with less flow ofc
 
The heat pump is running 24/7 and 7c for a chilled water circuit is ideal.

The water treatment used within the system is of a higher grade than used in most PC water cooling systems. The use of a metering station will actualy give me very close control over the flow rate. The heat pump is a dual circuit and the presure would not be high no more than 1.5 Bar. My biggest concern is condensation and the due point of air.
