EF to UEF Conversion
On June 12, 2017, the water heater industry was required by the U.S Department of Energy (DOE) to transition from the well-known Energy Factor (EF) metric for water heater efficiency to an entirely new metric called Uniform Energy Factor, or UEF. In addition to the change from EF to UEF, manufacturers are required to use an entirely new First Hour Rating (FHR) test procedure. While the name of the metric remains the same (FHR), the resultant values will likely be different from the previous FHR values for the same models due to the new test procedures. Take a look at the full press release below.
Are You NAECA Ready?
On April 16, 2015, new water heater energy factor (EF) requirements took effect as the result of updates to the National Appliance Energy Conservation Act (NAECA). These requirements call for higher energy factor (EF) ratings on virtually all residential gas, electric, oil, and tankless gas water heaters, completely altering the water heater landscape. NAECA 2015 also affects some light-duty commercial water heaters. Bradford White has a comprehensive line of NAECA 2015 products to meet your needs.
