FABRICATED COP, COP2, HSPF2, AND HEATING CAPACITIES
Copycat brands fake heating performance exactly the way they fake cooling performance.
They publish heating capacities, COP, COP2 values, and HSPF2 ratings that contradict basic thermodynamics, AHRI 210/240 test behavior, NRCan classifications, and their own watt inputs. A single hardware platform cannot legitimately produce multiple heating capacities, multiple COP values, and multiple HSPF2 results depending on which sticker is applied to the front panel, especially when the efficiencies are all similar. These inconsistencies do not come from a laboratory; they come from a spreadsheet.
The same Nordica machine, with the identical compressor, coil surface area, refrigerant charge, airflow system, motor, and electronics, and chassis geometry, is advertised as having a heating output of 10,000-11,970 BTU.
Nordica claims 9,000 BTU; DesignLine claims 11,200 BTU. There is no physical basis for a 19%+ variation in heating capacity unless the hardware changes. It does not. Every capacity value above the lowest real number is fabricated.
The COP, COP2, and HSPF2 values are even more revealing. Under AHRI 210/240, inverter heat pump efficiency follows a predictable pattern: lower-capacity units produce higher COP, and higher-capacity units produce lower COP. The copycat ratings show the opposite. These brands claim that higher heating capacity comes with equal or even higher COP, an outcome that is impossible for this small coil size, this compressor, and this airflow configuration. These contradictions alone prove that the data were not measured in a lab but simply invented.
Direct math exposes the fraud.
This violates the AHRI 210/240 performance curves, compressor limits, heat-exchange capacity, and basic thermodynamics.
A rebranded product can’t outperform the manufacturer’s already-inflated ratings without replacing the hardware. No such redesign exists.
A heat pump cannot increase its heating capacity by 40% without a larger compressor, larger coils, a different refrigerant, higher airflow, higher input power, a different metering device, and revised firmware. None of these changes were made. The numbers are fabricated.
The fraud becomes undeniable when the data is organized. Below are tables that sort ratings and capacities in different orders to expose the scam.
Sorted by Capacity
Capacity and efficiency are related in real-world data. Of course, there is no relationship whatsoever here.

Sorted by Efficiency
If the data were real, more efficient units would have a lower capacity. Here, where fake data rules, higher-capacity units are more efficient. Note that this table ignores the brand’s efficiency rating and instead uses the calculated efficiency based on the capacity and wattage input they claim.

Calculated COP Compared to Published COP
Here, you can see that almost none of the COP’s claims align with what is calculated from the brands’ published data. Once again, it’s hard to overstate how sloppy these fabricated numbers are!

HSPF2 Compare
The three brands that publish an HSPF2 all conflict with the data. Does it make sense that Zymbo manufactures the units for Silktech and Ortech, yet Silktech claims a 6,7 HSPF2 at 8,800 BTU and Ortech has a higher HSPF2 with a higher capacity?? Odd as well that Dubbll claims the same HSPF2 as Nordica- which makes Dubbll’s unit, yet somehow uses less power. These numbers defy basic thermodynamics.

Every heating rating published by these brands violates Energy Efficiency Regulations, AHRI 210/240 heating test requirements, ASHRAE 37 procedures, the Competition Act (R.S.C., 1985, c. C-34) prohibition on false representations, and Energy Efficiency Regulations, CSA C744 Table 7 for products falsely labeled as PTHPs. No copycat brand has a valid AHRI heating certification, a valid SCC-Accredited Certification Body heating test report, consistent heating data across revisions, or any published numbers that match the OEM’s actual performance.
Heating performance claims across these brands are contradictory, mathematically and physically impossible, legally non-compliant, unsupported by any certified data, incompatible with NRCan classification rules, and in violation of AHRI 210/240 and the Competition Bureau law. A single unit cannot legitimately possess different heating capacities, multiple conflicting COP values, multiple inconsistent HSPF2 ratings, contradictory watt inputs, or identical COP at radically different BTUs. The contradictions prove intentional fabrication.
