Silktech EcoAuro 2.0 is Illegal and Non-Compliant

EcoAuro 2.0

Failure to be listed in the NRCan Searchable Product List

In Canada, all air-conditioning and heat-pump systems must be listed in the NRCan database. In fact, it is illegal to import or sell a unit that is not listed. At the time of this publication, March 16, 2026, the Silktech EcoAuro 2.0 was not listed in the NRCan Searchable Product List.

Failure to meet NRCan Minimum Efficiency Requirements

Silktech EcoAuro 2.0 has a published rated capacity of 12,030 BTU in its brochure. Under federal law, any 12,030 BTU heat pump in this class must meet a 13.4 SEER2 or 9.3 CEER minimum to be legally sold, installed, or used in Canada. The Silktech EcoAuro 2.0 fails to publish a SEER2 or CEER value in its documentation because the unit cannot meet the required 13.4 SEER2 or CEER when tested in a certified lab.

Illegal Rating

Silktech uses the wrong rating metric in their published documentation, EER instead of SEER2 or CEER, COP2 instead of HSPF2. Silktech publishes only an EER for cooling and a COP for heating. Neither EER nor COP is a legal rating for this product category. For a heat pump, federal law requires SEER2 and HSPF2 ratings, or CEER. This alone renders the units illegal.

Illegal Misclassification

By using an EER instead of SEER2, Silktech is classifying EcoAuro 2.0 as PTHP, but EcoAuro does not meet the PTHP definition under Energy Efficiency Regulations. A lawful PTHP must have a wall sleeve, a separate unencased chassis, and a through-the-wall mounting. The Silktech EcoAuro 2.0 units lack these traits. Misclassifying the EcoAuro 2.0 as PTHP by using EER is a direct violation of NRCan rules and is illegal.

Miscalculated Performance Numbers

Silktech misrepresents even the fabricated numbers it publishes for Silktech EcoAuro 2.0 in both heating and cooling.

In Cooling

• Cooling Capacity: 12,030 BTU
• Power Input: 1,100 W

Using their own watt input: 12,030 ÷ 1,100 = EER 10.94. Yet, Silktech publishes 11.6 EER. Fraudulently lists the cooling capacity as 12,030 BTU with an EER of 11.6. When calculating the numbers, the EER of 10.94 is illegal. Can’t these cheaters do simple math??!!

In Heating

• Heating Capacity: 11,970 BTU
• Power Input: 1,010 W

Using their own watt input: 11,970 ÷ 3.412 (BTU to W) ÷ 1,010 = 3.47 COP. Yet, Silktech fraudulently publishes 3.66 COP. None of the numbers they publish is consistent with their own data.

Fraudulent and Fake Numbers

The 12,030 BTU capacity they claim in printed brochures and technical documents, along with the 11.6 EER rating for the EcoAuro 2.0, is fake and fraudulent. When tested in a lab, this unit will not produce 12,030 BTU or an EER of 11.6. So, even ignoring the misclassification and wrong ratings, the actual numbers they claim are fake.

Somehow, this claimed 12,030 BTU of cooling gives an incredible 15.55 SEER2 when Silktech fraudulently publishes the data on the DOE CCMS Database website.

Here’s where it gets interesting. The manufacturer, Zymbo (China), lists numbers that differ significantly from those in Silktech's brochure for the same unit.

Zymbo claims the same unit, called Dolphin 40, has the same 12,000 BTU and a different efficiency of 10.5 EER. What’s even more fascinating is that Zymbo’s own internal calculations are inconsistent.

Here’s what Zymbo publishes:

In Cooling

• Cooling Capacity: 12,000 BTU
• Power Input: 1,209 W

Using their own watt input: 12,000 ÷ 1,209 = EER 9.93. Yet, Zymbo publishes 10.5 EER. The cooling capacity is fraudulently listed as 12,000 BTU with an EER of 10.5. When calculating the numbers, the EER2 is really 9.93, which is illegal.

Zymbo is manipulating the numbers. The numbers they initially published were too good to be true, so they simply “dumbed down” the efficiency and presented lower efficiency values.

When Silktech published its own figures, it used the real (but still fake) numbers that Zymbo publishes when uploading data to the DOE website, then decided that a SEER2 to 15.5 looked good and appeared compliant.

For the EcoAuro2.0, the claimed 12,030 BTU capacity and 11.6 EER rating are false. When tested in a lab, this unit will not produce 12,030 BTU and an EER of 11.6. So, even ignoring the misclassifications and incorrect ratings, the actual numbers they claim are fake and inconsistent with expected test results.

Regulatory Violation Summary: Silktech EcoAuro 2.0

EcoAuro 2.0 is illegal to distribute, specify, install, or use in the United States and Canada. Silktech's published cooling and heating efficiency numbers are fabricated, mathematically impossible, and directly contradict what proper testing would show. EcoAuro 2.0 fails to meet DOE and NRCan minimum efficiency requirements under every applicable classification. Where these products appear in official databases, they do so with falsified data, which compounds rather than resolves their violations.

These ratings cannot be made up. They must be established through testing in a genuine laboratory under the correct DOE and NRCan test procedures. The fact that fabricated data has been submitted to official government databases does not constitute compliance — it constitutes fraud.

Submitting falsified efficiency data to a government database is not a path to compliance. It is a separate and aggravated violation — constituting the filing of false information with a federal regulator.
