Introduction  
 
Water heaters are one of common appliance used in residential buildings, mosques and office 
buildings. The most common type of water heater used in Qatar is storage type electric water 
heater. Solar water heaters are gaining importance in recent days. Studies ha ve shown that 
water heaters consume around 5% of annual consumption in residential buildings. This  
standard  is developed to ensure that the energy efficiency aspects of storage water heaters are 
monitored and controlled.  
This standard is  set to take effect  fully six (6) months following its publication in the Official 
Gazette of the State of Qatar

 1  SCOPE & OBJECTIVE  
 
1 1 Scope:  
This standard establishes requirements for energy  efficiency labeling of storage  
type electric water heater up to capacity of     liters . This standard does not apply 
to safety requirements of water heaters . This standard does not apply to 
instantaneous water heaters and water heaters that use gas, solid or liquid fuels, 
solar water heaters and water heaters designed for making hot drinks only.  
 
1 2 Objective:  
The objective of this standard is to:  
a) Provide detailed information on the performance and energy labeling  
requirements which an storage type water heater  has to meet in order to carry 
a valid energy efficiency label; and  
b) Provide detailed information on the performance requirements which a 
storage type water heater has to meet in order to meet minimum energy  
performance standard requirements.

4  REGISTRATION REQUIREMENTS  
4 1 The information about registration requirement for energy labeling and MEPS  will 
be available in Qatar General Organization For Standardization.  KM-CN-Nov2015  Page   
 4 2 For registration of an water heater energy labeling  and MEPS with a test report in 
accordance with re cent edition of GSO IEC 60379:       An application shall be 
provided for each model, in accordance with Appendix A, and submitted to the
