Stiebel Eltron PSH 20
0.93 UEF DOE CCD · 2026-09-19Grade G: where this UEF sits among the 163 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, low draw pattern (a one- or two-person household).
You are checking the Stiebel Eltron PSH 20. It uses 2,413 kWh of electricity a year at the low draw pattern, the standard daily hot-water usage DOE tests against for a one- or two-person household. That is 26 kWh below the class median of 2,439 kWh, across the 163 models in the same class.
Energy use per year
2,413 kWh 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 electricity rate where you live.
That is below the median of 2,439 kWh for the 163 models registered in the same heater type and draw pattern; it ranks 9 of 163, lowest energy first.
Solid line: this model (2,413 kWh). Dashed line: the class median.

What it costs to install
Not published: Installed cost range
This model's rated tank size lies outside the range NLR REMDB's cost model was fitted on, and the range is not stretched past it.
The annual energy figure on this page does not depend on this range and is unaffected.
Safety record
No CPSC recall names this model.
Checked against the CPSC recall database. CPSC does not publish a model-level match for this product category, so this list is curated by hand from the manufacturer's recall filings.

The 2,413 kWh figure is computed by this site, not published by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, with the daily hot-water draw of the federal test. This model's UEF is 0.93. Because the registry fixes the UEF, the only assumption added here is the test's daily draw. The figure applies only at the low draw pattern, and a household that draws more or less hot water would use a different amount. The source is DOE CCD, retrieved 2026-09-19. The methodology page explains how the annual cost is calculated from these inputs.
The rank is 9th lowest of 163 models registered as an electric tank at the low draw pattern. That puts it in the lowest quarter of its class for energy use. Its figure is 26 kWh below the class median of 2,439 kWh. The comparison holds only for a one- or two-person household, and rankings at other draw patterns are not available here. The first hour rating, the gallons of hot water available in the first hour from a full tank, is 30 gallons. The rated volume is 21 gallons. The data does not show whether these capacities meet the needs of a household larger than the low draw pattern describes. A household with heavier use can compare options in the water heater selector by fuel, space and size.
The running cost is not stated here because it depends on your own utility electricity tariff. The cost calculator on your own ZIP applies that tariff to the 2,413 kWh figure at the low draw pattern. The installed price range is not published for this model, because its ratings lie outside the range the cost database's model was fitted on. The range is not stretched past that limit, so no installed price is available. To look for a unit in the same class, use the same-class replacement search by model number with PSH 20. The registry data for this page were retrieved on 2026-09-19, and later changes to the registry are not reflected.
