Instantaneous Gas Burning Water Heaters:

Energy Efficiency Criteria and Labeling Method for Energy Label Qualified Instantaneous Gas Burning Water Heaters

No. En-Tech 10004066240
Promulgated and in effect on September 26, 2011

I. Instantaneous gas burning water heaters (“products”) applying for Energy Label Certification shall meet the following requirements on scope, energy efficiency test conditions and methods, and energy efficiency criteria:

1. Scope:
Products shall meet the requirements of CNS 13603, and the definition of C.C.C. Code 8419.11.00.00-6 regarding non-electric instantaneous gas burning water heater, or be recognized by Bureau of Energy, MOEA.

2. Energy Efficiency Test Conditions and Methods
Thermal efficiencies of products applying for Energy Label Certification shall be measured in accordance with test conditions and methods specified in CNS 13603 and CNS 13605.

3. Energy Efficiency Criteria
Measured thermal efficiency and carbon monoxide (CO) concentration shall meet the following baseline values:
Fuel TypeExhaust TypeThermal Efficiency (%)CO Concentration (v/v %)
Liquefied Petroleum Gas (LPG); Natural Gas (NG)Forced exhaust (FE , FF type)Above 83.0%Under 0.14%
Natural exhaust (RF , CF type)Above 83.5%Under 0.14%
Natural exhaust (open type)Above 83.5%Under 0.03%


4. Further requirements for applying Energy Label Certification of instantaneous gas burning water heater:

(1) For multi-fuel models, the application for Energy Label Certification shall be made for individual fuel. The test report shall specify the type of fuel used.

(2) Type Test Reports submitted for applying Energy Label Certification shall not only contain values of measured thermal efficiency and CO concentration but also photos of product exterior and specification plate.

(3) For OEM products, which are the same with previously registered or type-approved models and therefore can not provide Certificates for Registration of Product Certification or Type Approval Certificates, the documents below shall also be prepared for applying Energy Label Certification:
i.A photo of product specification plate that states the model number of the referred registered or type-approved model;
ii.A certificate of conformity issued by designated testing laboratory;
iii.A photocopy with company seal of the Certificate for Registration of Product Certification or the Type Approval Certificates of the original registered or type-approved model;
iv.The original type test report of the referred registered or type-approved model.

II. Notes on product labeling:
(1)The name and address of the label user shall be clearly displayed on the product or product packaging;
(2)If the label user is an agent, the name and address of the product manufacturer shall also be clearly displayed on the product or product packaging;
(3)The product's measured thermal efficiency shall be stated in the product catalog;
(4)The measured value of thermal efficiency shall be rounded to one decimal place. The value of CO concentration shall be rounded to two decimal places.
