Vancepic VH19K-NG

This site calculates the 206 therms figure; the registry does not list it. The calculation uses the registry's UEF, the ratio of hot water delivered to energy used, and the DOE test's daily hot-water draw for the high draw pattern. For this model the UEF is 0.82, from the DOE CCD, retrieved 2026-09-19. The class has 397 gas tankless units registered at the high draw pattern. By lowest energy use, this model ranks 229th of 397. That puts it in the second-highest quarter of its class for energy use. The figure applies only at the federal test's daily draw. The calculation steps are set out in how the annual cost is calculated.

The high draw pattern stands for a larger household, or one where showers and laundry overlap. The 182 therms median comes from that same group, so the 24 therms gap compares units tested at the same draw. The registered maximum flow rate in gallons per minute for this unit is 8.5. If you are checking a quote or a listing, confirm that the model number VH19K-NG matches this class and the UEF of 0.82. If the 24 therms gap matters for your home, you can find a same-class replacement by model number. The registry has no data on how this unit performs outside the test conditions.

The running cost is not given in this text. It depends on your state's average residential gas price, so the page calculates it from your ZIP. That calculation uses the same 206 therms of natural gas at the high draw pattern. At the same draw, this model uses 24 therms more than its class median, so its cost at any given rate is higher than the median unit's. The size of that difference cannot be shown without your rate. For a household that draws less than the high draw pattern assumes, the 206 therms figure does not describe its use. No registry value covers that case. To see the cost at your rate, use the cost calculator on your own ZIP.
