Is the Ruud PROE40 T2 RU95 right for your installation?
The Ruud PROE40 T2 RU95 is a narrow, tall electric tank for installations with more headroom than floor space. The body measures 60¾ inches high by 19¼ inches in diameter, and the water connections are at 63⅝ inches. That connection height matters when replacing a tank beneath shelves, overhead piping or a low ceiling.
Ruud lists 40 gallons nominal, 36 gallons of rated storage and a 55-gallon first-hour rating. WHE compares those figures with how your current heater performs during overlapping showers and appliance use. A matching gallon label alone does not establish that a new heater will fit or solve a hot-water shortage.
Image note: Ruud supplies one tall-tank photograph for this family. It is a representative manufacturer image; individual tall models differ in proportions. Use the dimensions above to judge fit.

Rated storage, first-hour delivery and UEF measure different things. They do not by themselves establish a number of showers or a household’s energy bill.
Dimensions, connections and replacement fit
Allow room above the 63⅝-inch water-connection height for the actual fittings, shutoff arrangement and service work. This model’s narrow diameter can help in a closet, but the access door, pan and nearby equipment can be more restrictive than the open floor area.
Ruud does not attach a required external-blanket footnote to this model’s row. Do not add another model’s blanket dimensions or assume an optional accessory is included. The exact supplied equipment and instructions govern the finished installation.
WHE checks the full delivery route, supporting surface, drain pan, nearby pipes and access to the front panels, drain valve and anode. The tank dimensions are not minimum installation clearances. We also review water pressure, thermal expansion and temperature-and-pressure relief discharge as part of the scope.

| Model | Nominal / rated gallons | First-hour gallons | Body height × diameter |
|---|---|---|---|
| PROE40 T2 RU95 (tall) | 40 / 36 | 55 | 60¾ × 19¼ in. |
| PROE40 M2 RU95 (medium) | 40 / 36 | 55 | 48¼ × 20¼ in. |
| PROE50 T2 RU95 (tall) | 50 / 45 | 63 | 58⅝ × 20¼ in. |
The medium 40 has the same 36-gallon rated storage, 55-gallon first-hour rating and 0.93 UEF. Its body is 12½ inches shorter and one inch wider, making it a meaningful alternative when headroom is limited. The tall 50 increases rated storage to 45 gallons and first-hour delivery to 63 gallons. Interestingly, its body is 2⅛ inches shorter than this tall 40, although it is one inch wider. Capacity and height do not increase together across every model.
WHE sizes around peak use, including shower flow, tub volume and overlapping appliances. These standard configurations share 21 GPH recovery at a 90°F rise; a larger tank does not automatically reheat faster.
Electrical configuration and installation planning
Standard power is 240V AC, single phase, with two 4,500W elements operating one at a time. Ruud notes special-order electrical options; the ratings here are for the standard configuration.
WHE checks the delivered nameplate and wiring diagram against the available circuit. These conventional tanks have no combustion flue or heat-pump condensate system. If considering relocation from an attic to a garage, send photos of both locations for an estimate.
Maintenance and warranty
The series sheet lists stainless steel elements, an anode, Ruudglas tank lining, an EverKleen diffuser and a brass drain valve. Follow the supplied manual for sediment maintenance and anode inspection; the diffuser does not make the heater maintenance-free.
The linked AP16826-2 certificate (September 2014) provides six-year limited tank and parts coverage for eligible single-family use by the original owner, and lists one year for other locations. Labor, removal and reinstallation are excluded. Confirm the supplied certificate and retain your records. ProtectionPlus is a separate extension.
Manufacturer documentation and product-image notes
The specifications above come from Ruud’s May 2024 PROE RU N Rev. 16 specification sheet, linked from its Professional Achiever Standard Electric family page. Sources checked October 17, 2026.
The webpage’s model table uses the older Energy Factor label and shows 0.95 on many rows. EF and UEF are different measures; this guide uses the linked sheet’s model-specific UEF values. The webpage also describes a copper upper element while the sheet says stainless steel upper and lower elements. The sheet is the basis here, with the supplied nameplate and parts documentation checked for the actual heater.
Ruud also links the general AP9029-12 use-and-care manual (January 2015) and six-year limited warranty certificate. Use these references alongside the exact instructions delivered with the unit. A family photo or optional feature mentioned elsewhere on the page does not establish an included accessory.

Ruud PROE40 T2 RU95 FAQs
How much water does the PROE40 T2 RU95 store?
It is a 40-gallon nominal model with 36 gallons of rated storage. The 55-gallon first-hour rating measures delivery during a standardized hour, including newly heated water; it is not the amount stored at once.
Does the tall 40 deliver more hot water than the medium 40?
Ruud lists the same 55-gallon first-hour rating and 36-gallon rated storage for both. The main difference is their shape: 60¾ × 19¼ inches for the tall body versus 48¼ × 20¼ inches for the medium.
Do both 4,500W elements run at the same time?
Not in Ruud’s standard configuration. The sheet specifies non-simultaneous operation, meaning the controls operate one element at a time. This is not a standard 9,000W simultaneous heater. WHE verifies the nameplate and circuit before installation.
Does the series name guarantee smart controls or automatic leak shutoff?
No. The documents used for this guide do not establish Wi-Fi or automatic leak shutoff as included features of this exact standard model. The webpage mentions System Sentinel only for selected configurations; it is not assumed included here.
Does the six-year warranty include labor?
No. Ruud’s linked certificate excludes labor, removal and reinstallation costs. The six-year tank and parts term is for eligible single-family use; the certificate sets different terms for other installations. ProtectionPlus is a separate extension, not the base warranty.
