Where the Bradford White RE340T6 fits
The RE340T6 trades a taller body for a 20-inch jacket. It is the tall 40-gallon choice in this group, with 36 gallons of rated storage and a 53-gallon first-hour rating. Overhead connections are the main fit detail to resolve before ordering.
A narrow closet can make this model worth comparing with the wider short options, provided there is enough height to install and service it. The water and relief-valve connections sit above the stated heater-top dimension. A shelf that clears the body may still obstruct the fittings, wiring or anode service. WHE checks the route into the space and the arrangement of the existing pipes before treating this as a straightforward replacement.
Capacity, delivery and efficiency
Bradford White’s September 2026 U.S. specification lists 40 gallons nominal capacity, 36 gallons DOE rated storage, a 53-gallon first-hour rating and 0.92 UEF. Nominal capacity is the model’s size category; rated storage is the published stored volume. First-hour rating includes reheating during a standardized hour and should not be read as the amount held in the tank at once.
Use the first-hour figure to compare a busy period of use, then discuss the actual fixtures and timing. It is not a promise of a particular household size or an endless sequence of showers. UEF is a standardized efficiency measure, not a forecast of your bill. WHE does not assign a dollar saving without the existing heater, water use and electricity cost.
Dimensions and replacement access
- A — floor to top of heater: 60 3/16 inches.
- B — jacket diameter: 20 inches.
- C and E — floor to water and T&P connections: 62 7/16 inches.
- D — water-connection center spacing: 8 inches.
- G — water connections: 3/4-inch NPT.
- Approximate shipping weight: 125 pounds; this is not the filled operating weight.
The RE250T6 comparison is useful when an owner assumes only a 40-gallon heater can fit. It is not an automatic upgrade recommendation: WHE still checks connections, pan, access, demand and the supplied electrical rating. The actual dimension rows give a better answer than relying on the words 40-gallon and 50-gallon.
RE340T6 is not one of the two supplied-blanket models marked in this specification table. Its jacket diameter should still not be treated as a complete installation footprint. Allow room for the pan, pipework and access to the element covers, drain and anode. Check the instructions delivered with the heater for the actual installation.
Compare the closest current models
The RE340R6 is 47 3/16 inches high with a 22-inch jacket and a 52-gallon first-hour rating. The RE340S6 shares those dimensions but lists 49 gallons in the first hour. For more storage, the RE250T6 has a 20-inch jacket, a 59-inch heater height, 45 gallons of rated storage and a 64-gallon first-hour rating. A higher nominal capacity is not always a taller tank.
Electrical configuration and recovery
This guide uses the sheet’s standard 240V, single-phase, non-simultaneous configuration with two 4,500W elements. Only one element operates at a time. The published recovery table gives 21 gallons per hour at a 90°F temperature rise for 4,500W operation. Recovery changes with the required rise and selected input; that figure is not the first-hour rating.
The RE340T6 row permits element wattages from 4,000W to 6,000W, subject to the voltage and wiring restrictions in the sheet. That ordering range is not an instruction to increase input on an existing circuit. Other factory configurations require separate verification. WHE checks the full nameplate, supply, circuit and wiring arrangement before installation; the base model number alone does not prove every electrical detail.
Installation and maintenance considerations
This is an indoor electric storage heater. WHE reviews the supporting surface, leak-management arrangement, shutoff access, relief discharge and thermal-expansion provisions where the supply is closed. Future service access matters even when the tank itself fits. If the present location is an attic, we can discuss whether a garage relocation is practical and include the necessary work in the estimate.
Sediment maintenance and anode inspection remain relevant. A sediment-control feature does not make the heater maintenance-free. Keep the model, serial number and installation record together, and report leaks, a change in hot-water delivery or repeated electrical trips for assessment. Have electrical diagnosis and internal service performed by a qualified professional following the supplied instructions.
Six-year model and warranty terms
The final 6 identifies the six-year tank model; the sheet lists 10-year versions separately. The current residential certificate provides six-year limited tank and component-parts coverage for qualifying single-family use, subject to its conditions. It shortens these terms to one year for other residential use of a six-year model and excludes nonresidential or commercial use. It also excludes replacement and repair costs, including removal, installation and associated charges, subject to applicable law. Retain the certificate supplied with the heater and confirm eligibility using the complete model and serial number.

Bradford White RE340T6 FAQs
How tall is RE340T6 including its connection height?
The current sheet lists 60 3/16 inches to the heater top and 62 7/16 inches to the water and T&P connections. Installation and service space must be added.
Is the 50-gallon RE250T6 necessarily taller?
No. RE250T6 is listed at 59 inches to the heater top and 60 1/4 inches to the water connections, with the same 20-inch jacket. Its rated storage is 45 gallons, compared with 36 for RE340T6.
Do both 4,500W elements operate together?
The standard configuration in the current sheet is 240V, single-phase and non-simultaneous. The controls energize one element at a time. Two elements do not make this a standard 9,000W simultaneous heater. Confirm the supplied nameplate.
Does the six-year warranty cover installation labor?
The current residential certificate provides six-year limited tank and parts terms for qualifying single-family use of this six-year model. It excludes replacement and repair costs such as removal, installation and associated charges, subject to applicable law. Other residential uses have shorter terms; the supplied certificate controls.
Can WHE assess RE340T6 for my home?
Yes. Send the existing model label, a wide installation photo and your hot-water concerns. WHE checks fit, demand, electrical supply and the scope of work for homes in Palm Beach Gardens, Jupiter and nearby Palm Beach County communities. Booking starts an estimate; equipment availability and scheduling are confirmed afterward.
