Thermal approach
Inlet and outlet temperatures under representative demand indicate how effectively heat is being transferred.
System component / plate heat exchangers
TRANSFER PERFORMANCE, MEASURED.
The plate heat exchanger transfers energy while keeping primary network water separate from dwelling services.

Restriction and fouling
Flow restriction or fouling cannot be concluded from outlet temperature alone; surrounding hydraulic conditions matter.
Attendance required
Conclusive diagnosis requires an engineer on site to measure temperatures, pressures, flow, electrical supply and control response under operating conditions.
