BRADFORD WHITE RTG-K-199N1

0.95 UEF DOE CCD · 2026-09-19
B

Grade B: where this UEF sits among the 397 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set

A gas tankless unit, high draw pattern (a larger household, or one where showers and laundry overlap).

If you are verifying a listing, this page checks one unit against its class. The BRADFORD WHITE RTG-K-199N1 uses 178 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 4 therms below the class median of 182 therms.


Energy use per year

178 therms a year

Computed by this site from the registry's UEF and the federal test's daily hot-water draw for this draw pattern. What it costs depends on the natural gas rate where you live.

That is below the median of 182 therms for the 397 models registered in the same heater type and draw pattern; it ranks 45 of 397, lowest energy first.

This model: 178 therms

Solid line: this model (178 therms). Dashed line: the class median.

What these figures mean

The registry lists a UEF, the ratio of hot water delivered to energy used, of 0.95 for this model. This site combined that UEF with the DOE test's daily hot-water draw for the high draw pattern. The registry does not list the annual figure; this site computed it. The result is 178 therms of natural gas, with source data retrieved from DOE CCD on 2026-09-19. The figure applies only at the federal test's draw, not to use in a particular home. The listed maximum flow rate in gallons per minute is 5.4, which is a separate value from the annual energy figure.

The comparison group is the 397 models registered as a gas tankless unit at the high draw pattern. This model uses 4 therms less than the class median of 182 therms. Its rank is 45th lowest energy use of 397, which places it in the lowest quarter of its class for energy use. Rank counts from the lowest energy use upward. Both the class median and this model's figure are stated in therms of natural gas. This page does not rank the model at any other draw pattern. To narrow a group by fuel, space and size, use the water heater selector.

This comparison suits a larger household, or one where showers and laundry overlap, because that is what the high draw pattern represents. It does not suit a household with a different usage, because 178 therms applies only at the high draw pattern. The running cost is not stated in this text. It depends on the state average residential gas price, so it is computed from your ZIP. The cost calculator for your own ZIP does that calculation, and the methodology for the annual cost explains how it works. To look for a same-class unit, the replacement finder by model number can start from RTG-K-199N1. The modeled installed-cost range appears in its own block on this page, with its source and date.
