Ranein RH12KG-C-LPG
0.82 UEF DOE CCD · 2026-09-19Grade G: 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 checking the Ranein RH12KG-C-LPG, a gas tankless unit, this is its yearly energy use. It uses 206 therms of natural gas at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 24 therms above the 182 therms median for its 397-model class, ranking 229th lowest in energy use.
Energy use per year
206 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 above the median of 182 therms for the 397 models registered in the same heater type and draw pattern; it ranks 229 of 397, lowest energy first.
Solid line: this model (206 therms). Dashed line: the class median.

This site calculated the 206 therms figure. The registry does not publish it. The figure combines the registry's UEF, the ratio of hot water delivered to energy used, with the DOE test's daily hot-water draw for the high draw pattern. For the Ranein RH12KG-C-LPG, the UEF is 0.82. The registry data came from the DOE CCD and was retrieved on 2026-09-19. The figure holds only at the federal test's daily draw. A home that uses more hot water than the test assumes will burn more than 206 therms of natural gas. A home that uses less will burn less. The data does not include any single household's own daily draw. The page on how the annual cost is calculated sets out the steps behind the figure.
The high draw pattern represents a larger household, or one where showers and laundry overlap. This unit's maximum flow rate in gallons per minute is 5.1. It is compared with the 397 gas tankless models registered at the same draw pattern. Against that group, its 206 therms sits 24 therms above the class median of 182 therms. Its rank of 229th lowest places it in the second-highest quarter of its class for energy use. A quote may describe this model as a low-use option within its class. The registry data does not support that description. To compare other models in the same class by model number, use find a same-class replacement.
This page does not state the running cost. The cost depends on your state's average residential gas price. The page calculates it from your ZIP code, using the 206 therms yearly figure. Readers in different states will therefore see different running costs for the same Ranein RH12KG-C-LPG. The 24 therms gap above the class median also changes with that price, so its cost differs by state. To run the figure at your own price, use the cost calculator for your ZIP code. The installed price range appears in its own block on this page, with its source and date. It is a modeled range of installed cost, not a quote, and this section does not repeat it.
