Short answer: A two-clamp energy monitor can help separate a heat-pump circuit from another accessible circuit, but it cannot identify every cause of a higher bill by itself. The documented Equipmentone meter supplies two 80 A CTs, supports AC 100-240 V and lists a 0.2-80 A measuring range. Treat those as product facts to check against the intended circuit. Physical access, safe isolation and the meaning of readings still need to be established for the actual installation. WiFi bi-directional 2-channel energy meter with dual 80 A CTs is the documented product used for this comparison.

Match the CT range to the intended circuit

QuestionUseful channel planDo not assume
Heat-pump drawOne channel on the accessible heat-pump conductorThat the clamp fits every enclosure
Comparison loadSecond channel on a separate conductorThat two clamps measure one combined bundle separately
WiFi recordTuya-compatible connectionThat every historical-data feature is documented
  1. Define whether you need a heat-pump reading, a comparison reading or both.
  2. Confirm that each intended conductor is physically accessible to the installer.
  3. Check the two-CT package and electrical markings.
  4. Record the first readings with the circuit labels kept consistent.

Safety boundary for consumer-unit work

The listing does not specify heat-pump efficiency, tariff savings, seasonal performance, power factor, installation dimensions or a diagnosis of the appliance. A monitor records an electrical view; it does not replace service data.

Use the monitor to frame a better question

Choose the dual-CT unit when two named circuits can be monitored safely and the resulting readings will answer a specific household question. For related context, see WiFi Dual-CT Energy Meter UK: What to Check Before Buying. For related context, see WiFi Energy Meter for a Consumer Unit: Two-Channel Buyer Checks. The documented next step is the WiFi bi-directional 2-channel energy meter with dual 80 A CTs.
