My Heatpump App Enhancement Suggestion - GSHP Brine Temperature Tracking

[MarshFlattsFarm]

With a Ground Source Heat Pump, it is the incoming temperature of the 'brine' from the Ground Loop that is especially interesting to correlate with CoP - rather more than the outdoor air temperature (though that is useful to retain too, as a proxy for heat demand when under Weather Compensation control - plus it is useful to compare the incoming 'brine' (i.e. the ground) temperature with the air temperature).

Would it be possible to add the Flow (input) temperature of the 'brine' circuit to the My Heatpump App?

• This would need to be optional, since it only applies to Ground (and Water) Source systems, not ASHPs
• Ideally also include the Return (output) temperature of the 'brine' circuit, for awareness of deltaT and to observe if this goes below freezing (i.e. tending to try to freeze the ground)

This is probably a relatively niche requirement, so difficult to argue it should be given a high priority but perhaps consider when making other changes to My Heatpump.

[GSHPs gain a thermodynamic advantage over ASHPs by accessing ambient heat at a higher temperature - e.g. in December the ground is often still at 10C when the air is at 0C, especially overnight. GSHPs also have no need for defrost cycles. It is interesting to research whether these characteristics translate into meaningful real-world efficiency advantages over ASHPs.]

Check +1, also a 5.8kW heatpump with a 140m deep vertical heat exchanger. Double 32mm loop. So around 560 meters of 32x3mm PE tubing. Monitoring brine in and out and much more ☺️. In the meantime I think we can use the brine inlet temp as air temp.
