IBC Technologies SFT 199-1
0.9 UEF DOE CCD · 2026-09-19Grade D: 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).
Checking the IBC Technologies SFT 199-1? It uses 188 therms of natural gas a year at the high draw pattern, the standard daily hot-water usage DOE tests against. That is 6 therms above the class median of 182 therms. Its rank is 218th lowest of 397 models.
Energy use per year
188 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 218 of 397, lowest energy first.
Solid line: this model (188 therms). Dashed line: the class median.

The figure of 188 therms is computed by this site, not the registry. It applies the registry's UEF, the ratio of hot water delivered to energy used, to the DOE test's daily draw. The listed UEF is 0.9. The registry also lists a maximum flow rate in gallons per minute of 5.3. That flow rate is not part of the energy calculation. The figure belongs only to the high draw pattern, which describes a larger household, or one where showers and laundry overlap. The source is the DOE CCD, retrieved 2026-09-19.
This model is one of the 397 registered as a gas tankless unit at the high draw pattern. Its 188 therms is 6 therms above the class median of 182 therms. Its rank is 218th lowest energy use of 397, which places it in the second-highest quarter of its class for energy use. It fits a household that matches the high draw pattern and accepts energy use above the median. It does not fit a reader who wants energy use at or below 182 therms. To compare, find a same-class replacement by model number or use the selector by fuel, space and size.
The running cost of 188 therms of natural gas depends on your state average residential gas price. This page does not state an amount, because that price varies by state. Enter your ZIP in the cost calculator to apply that price to this model. The annual cost method explains how the therms are converted. The installed price range is in its own block, with its source and date. It is a modeled installed-cost range, not a quote. Actual use in your home is not available here, so a daily draw different from the high draw pattern will change the 188 therms figure.
