Why Silktech Heat Pump Is Highlighted for Claim Verification Issues

Author : Jordan Lee | Published On : 25 May 2026

Silktech's EcoAuro 1.0 and 2.0 heat pumps violate U.S. standards by exceeding the energy consumption limit while using fraudulent, inflated efficiency ratings. These units incorrectly report capacity and rely on fabricated figures for metrics such as EER and COP, leading to misleading marketing claims. As a result, users face higher electricity costs, reduced equipment lifespan, and unreliable heating or cooling performance, failing to meet legal, certified standards required for residential operation.

Silktech Units Fail Federal Efficiency Standards

Silktech's EcoAuro 1.0 and 2.0 HVAC units are ineligible for legal sale or installation in the US due to regulatory violations. While Silktech markets the EcoAura 1.0 at 8000 BTUs, official California Energy Commission data records it at 8831 BTUs. The higher capacity, along with EcoAuro 2.0's 12,030 BTUs, places both units under federal laws requiring a minimum SEER2 of 13.4. Because Silktech heat pumps have failed to provide certified test results proving these models meet the 13.4 SEER threshold, the units do not comply with Department of Energy (DOE) standards. Without these mandatory certifications, both models are being sold illegally because they fail to meet the minimum efficiency requirements for the American market.

Use of Inaccurate Efficiency Metrics

Rather than utilizing the required SEER2 (cooling efficiency) and HSPF2 (heating efficiency) ratings, Silktech depends on EER and COP values in its product documentation. These metrics do not apply to the category of systems being promoted. EER and COP are generally associated with Packaged Terminal Heat Pumps (PTHPs), not the type of systems represented by the EcoAuro models. Silktech employs alternative metrics that create a misleading impression of compliance with standards, bypassing the essential SEER2 and HSPF2 ratings. This misleads customers about the units' actual efficiency.

Incorrect Product Classification

Silktech incorrectly classifies the EcoAuro 1.0 and 2.0 as packaged terminal heat pumps (PTHPs). According to the Department of Energy (DOE) regulations (10 C.F.R. § 430.2), a true PTHP must have the following features:  

- A wall sleeve  

- A separate, unencased chassis  

- A design meant for through-the-wall installation  

Neither the EcoAuro model meets these essential requirements, making their classification invalid. Furthermore, even under the incorrect PTHP classification, the units still fail to meet the minimum efficiency standards. A compliant 8,000 BTU PTHP should have an Energy Efficiency Ratio (EER) of at least 11.6. However, Silktech lists the EcoAuro 1.0 with an EER of only 10.9, falling short of the legal requirement. This highlights both the misclassification and non-compliance of these products.  

Verified Performance Calculation Errors

There are significant errors in Silktech's published performance data. The EcoAuro 1.0 is promoted as having a cooling capacity of 8,000 BTU and a power input of 750 watts, which yields an EER of 10.67, not the claimed 10.91. The heating performance exhibits similar issues. With a stated heating capacity of 8,000 BTU and a power input of 700 watts, the calculated Coefficient of Performance (COP) is 3.35, while Silktech claims it is 3.4. These exaggerated figures misrepresent actual efficiency, leading to increased energy consumption and higher operating costs. 

Conclusion 

Silktech heat pumps do not comply with U.S. efficiency standards, use inaccurate performance metrics, and are misclassified according to federal regulations. Verified calculations show discrepancies in the company's published data, indicating overstatement of efficiency. Without certified evidence of meeting SEER2 requirements, these systems are not legally allowed for sale or installation in the United States.
