Richmond PROPH40 T0 RH120
2.59 UEF DOE CCD · 2026-09-19Grade D: where this UEF sits among the 426 models in its class, lowest (G) to highest (A). A position, not an official label. How the grade is set
An electric tank, medium draw pattern (a typical three- or four-person household, about 55 gallons on a busy morning).
If you are checking this model's rating: the Richmond PROPH40 T0 RH120, an electric tank, uses 1,254 kWh of electricity a year. That figure holds at the medium draw pattern, the standard daily hot-water usage DOE tests against. It sits 2,277 kWh below its class median of 3,531 kWh, ranking 129th lowest in energy use of 426 models.
Energy use per year
1,254 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 3,531 kWh for the 426 models registered in the same heater type and draw pattern; it ranks 129 of 426, lowest energy first.
Solid line: this model (1,254 kWh). Dashed line: the class median.

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 2.59 · Grade D Price it on your ZIP
This site computed the 1,254 kWh figure; it is not a value printed in the registry. The calculation combines two inputs. One is the registry's UEF, the ratio of hot water delivered to energy used, which is 2.59 for this model. The other is the DOE test's daily hot-water draw for the medium draw pattern. The UEF comes from the DOE certification database (CCD), retrieved 2026-09-19. The class above covers only models registered as an electric tank at the medium draw pattern. A household that uses more or less hot water than the test assumes will use a different amount of energy. That amount is not available on this page. The method is set out in how this site calculates annual energy and running cost.
The first hour rating, the gallons of hot water available in the first hour from a full tank, is 43 gallons. The rated volume is 37 gallons. The medium draw pattern represents a typical family household on a busy morning. Homes whose first-hour demand stays within 43 gallons match the conditions behind the 1,254 kWh figure. Homes that need more hot water in that first hour fall outside those test conditions. This page has no energy figure for them. To check other models by fuel, space and size, use the water heater selector by fuel, space and size. To compare this unit with others in its class, try the same-class replacement search by model number.
This text does not state a running cost. The cost depends on your own utility's electricity tariff, so the page works it out from your ZIP code and the 1,254 kWh figure. You can run it in the running-cost calculator for your ZIP code. The 2,277 kWh gap to the class median turns into a cost difference only at your own rate, so no cost figure is given here. This page also does not publish an installed price range for this model. Its ratings, including the UEF of 2.59, lie outside the range that the cost database's model was fitted on. The site does not stretch that range past its fitted limits, so the installed price is not available.
