Is the Ruud PROE30 T2 RU95 right for your installation?
A narrow utility space is the main reason to consider the Ruud PROE30 T2 RU95. Its 19-inch tank diameter is the smallest among the tall and medium models in this standard-electric group. The body is 47½ inches high, with the water-connection height listed separately at 50⅜ inches. It can be a practical comparison for a smaller existing electric tank when there is enough overhead room for piping and service.
The 30-gallon label is nominal: Ruud lists 27 gallons of rated storage and a 44-gallon first-hour rating. That is a modest reserve, so WHE asks about back-to-back showers, tub filling and simultaneous appliance use before recommending it. Choosing the narrowest tank is only useful if its delivery meets the home’s busiest period.
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
This tall 30 is shorter than the tall 40, so the word “tall” should not be treated as a fixed installation height. Its top connections still need room above the 50⅜-inch connection elevation. An existing shelf or valve can make a tank with a suitable body height difficult to install or maintain.
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 |
|---|---|---|---|
| PROE30 T2 RU95 (tall) | 30 / 27 | 44 | 47½ × 19 in. |
| PROE30 M2 RU95 (medium) | 30 / 27 | 45 | 37½ × 20¼ in. |
| PROE40 T2 RU95 (tall) | 40 / 36 | 55 | 60¾ × 19¼ in. |
The 30-gallon medium keeps the same 27 gallons of rated storage but lowers the body by 10 inches and widens it by 1¼ inches. Its first-hour rating is 45 gallons, only one gallon above the tall version. Moving to the tall 40 adds nine gallons of rated storage and 11 gallons in the first-hour test, while increasing body height to 60¾ inches. These are different tradeoffs: the medium mainly changes fit; the tall 40 changes reserve and delivery.
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 PROE30 T2 RU95 FAQs
How much water does the PROE30 T2 RU95 store?
It is a 30-gallon nominal model with 27 gallons of rated storage. The 44-gallon first-hour rating measures delivery during a standardized hour, including newly heated water; it is not the amount stored at once.
Is the 30-gallon tall narrower than the medium?
Yes. The tall is 19 inches in diameter and the medium is 20¼ inches. Both list 27 gallons of rated storage. Their tank heights are 47½ and 37½ inches respectively.
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.
