This unit is in compliance with DOE regulations, 10 CFR 430 .32 (d), which determines the amended energy conservation standards for residential water heaters.

  • Energy Factor > 0.82 (for gas models) and Energy Factor> 0.93 (for electric models)

This 5L LPG Portable unit has a Energy Factor Rate: 0.90

This item may have been previously marketed as a 1.5 gpm unit.  However a recent independent laboratory has done testing and determined/certified this unit has a maximum flow rate of 2.0 gpm. 

There appears to be some confusion as the Technical Specification from the manufacturer indicates this unit is a 2.0 maximum flow rate and the old shipping boxes, manuals and nomenclature on the unit may state 1.5 gal.  Again these units are 5 liter, 5L or 5LPM with a Maximum Flow Rate of 2.0 gpm. 

As a distributor of this product and I am under contract from the manufacturer and I have to display the information provided to me by the manufacturer.  Therefore, as per the MANUFACTURER,  this is a 2.0 gpm unit regardless of the packaging.
