Bradford White Corporation, headquartered in Ambler, Pennsylvania, is an American-owned and employee owned, full-line manufacturer of residential and commercial and industrial products for water heating, space heating, combination heating and storage applications.
Direct electric resistance tank water heaters are not included in the Energy Star program; however, the Energy Star program does include electric heat pump units with energy factors of 200% or higher. Tankless gas water heaters (as of 2015) must have an energy factor of 90% or higher for Energy Star qualification.
Prior to 1962, Zip focused primarily on water heaters for kitchens and hot water heaters for bathrooms. Zip began manufacturing and marketing in Australia from about 1947. An early Zip innovation was a manually operated over-sink boiling water heater with a "ready whistle" and automatic cut-off, which became a popular fixture in Australian restaurants and community kitchens during the 1950s ...
The energy factor metric only applies to residential water heaters, which are currently defined by fuel, type, and input capacity. [5] Generally, the EF number represents the thermal efficiency of the water heater as a percentage, since it is an average of the ratio of the theoretical heat required to raise the temperature of water drawn to the amount of energy actually consumed by the water ...
This heat must be dissipated from the load bank, either by air or by water, by forced means or convection. In a testing system, a resistive load simulates real-life resistive loads, such as incandescent lighting and heating loads as well as the resistive or unity power factor component of magnetic (motors, transformers) loads.
