Richmond 88H40*
0.81 UEF DOE CCD · 2026-09-19No A–G grade: Fewer than 8 models share this heater type, fuel and draw pattern, too few for a fair A-G scale.
A short tank built to sit under a counter, low draw pattern (a one- or two-person household).
Verifying the Richmond 88H40*: it uses 2,771 kWh of electricity a year under the low draw pattern, the standard daily hot-water usage DOE tests against, which represents a one- or two-person household. No class median is given, because too few models share this class and draw pattern.
Energy use per year
2,771 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.
Not published: Class comparison
Too few models share this heater type and draw pattern for a fair class median, so no comparison is shown.
The yearly energy figure above stands on its own and does not depend on the class.
What it costs to run where you live
What the registry files
- UEF (Uniform Energy Factor) how much hot water you get for each unit of energy the heater uses
- 0.81 DOE CCD · 2026-09-19 Compared only with other models registered as a short tank built to sit under a counter at the low draw pattern.
- Draw Pattern the standard daily usage profile DOE tests the unit against
- Low DOE CCD · 2026-09-19
- First Hour Rating how many gallons of hot water the unit can deliver in one hour, starting from a full tank
- 50 gal DOE CCD · 2026-09-19
- Rated Storage Volume the tank size in gallons
- 36 gal DOE CCD · 2026-09-19
What it costs to install
Not published: Installed cost range
This model's UEF 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.

UEF 0.81 Price it on your ZIP
The figure of 2,771 kWh was computed by this site, not by the registry. It combines the registry's UEF, the ratio of hot water delivered to energy used, of 0.81 with the DOE test's daily hot-water draw for the low draw pattern. The fuel is electricity. The condition matters: the figure describes the federal test's daily draw, not a measured household. The source is the DOE CCD, retrieved 2026-09-19. A reader checking the number can repeat the calculation from the 0.81 rating and the daily draw for this pattern, and the methodology page sets out how the annual cost is calculated from it.
This unit is a short tank built to sit under a counter, with a rated volume of 36 gallons. Its first hour rating, the gallons of hot water available in the first hour from a full tank, is 50 gallons. The 2,771 kWh figure belongs to the low draw pattern, so it matches a one- or two-person household and no other. A household with a higher draw pattern would use a different amount, and this page does not state that amount. To compare units by fuel, space and size, use the water heater selector, or find a same-class replacement by model number.
The running cost of 2,771 kWh depends on the electricity tariff the reader pays, so this text states no cost. The cost calculator applies the rate for the reader's own ZIP to that annual energy. Two other values are not available for this model. No class median or rank is shown, because too few models share this class and draw pattern for a fair comparison. No installed price range is published either, because the ratings of 0.81 UEF and 50 gallons first hour rating lie outside the range the cost database's model was fitted on. Both values are unknown here, and neither is estimated.
