Sizing Water Heaters
Sizing is the technique that matches the capacity of the hot water source to your needs. For tank water heaters, the key criterion is hot water storage capacity. For tankless water heaters, the key criterion is hot water flow rate. Incoming water temperature is a critical consideration, which varies by region and season. That is, a water heater in the North—either tank or tankless—will need a higher BTU input in the winter than the summer to heat and deliver water to a given temperature. Professional Classic Power Vent Rheem Water Heater offer 40 and 50 gallon capacities.

Energy Efficiency in Water Heaters
What’s the Difference Between High Efficiency (EF) Ratings and the New Uniform Energy Factor (UEF)? If you’ve ever researched water heaters before a purchase, then you’ve probably compared high efficiency, mid-efficiency and standard efficiency information. To help consumers in their water heater purchase decisions, the Department of Energy has developed new industry standards. Beginning, June 12, 2017, EF ratings have been replaced with the new industry standard for measuring energy efficiency in water heaters called, Uniform Energy Factor (UEF).

The new UEF standard affects more than just the efficiency number itself. Adjustments in new DOE testing procedures now impact water heating performance stats associated with the amount of hot water produced in a real-world situation to the length of typical showers. Examples of Performance Factors Impacted by UEF include:

  • First Hour Rating / First Hour Delivery (FHR / FHD) – The amount of hot water a waterheater can provide in the first hour of operation. Updated testing procedures result ina more accurate representation of performance.
  • Capacity – Previously, capacity was expressed as a single number that didn’t fullyrepresent the actual storage capacity of the water heater. With the UEF regulations,the DOE now requires manufacturers to inform buyers of both a water heaters’nominal capacity by gallon grouping (40, 50, 60 gallon, etc.), as well as the actualstorage capacity (35, 37, 42, 58 gallon).
  • Estimated Energy Cost Savings – The updated testing procedures enable a moreaccurate approximation of what it will cost to run a particular water heater.
