Where the Bradford White RE240L6 fits
The RE240L6 is a 38-gallon nominal lowboy with a supplied insulation blanket. Its published 24-inch diameter describes the bare jacket, so the completed installation needs more width than that single dimension suggests. It is worth comparing directly with RE240LN6 before choosing a replacement.
The current sheet lists 35 gallons of DOE rated storage and a 49-gallon first-hour rating. That first-hour figure includes reheating during the test; it is not the amount of water stored in the tank at once. WHE considers the busiest period of use, fixture demand and the existing heater’s performance alongside the available space.
Capacity, delivery and efficiency
The current specification lists 38 gallons nominal capacity, 35 gallons DOE rated storage, a 49-gallon first-hour rating and 0.91 UEF. Nominal capacity describes the listed size; rated storage is the separately published stored volume. First-hour rating combines stored hot water and recovery during a standardized test hour.
Compare first-hour ratings when considering a busy period, but do not treat them as a guaranteed number of showers. UEF is a standardized efficiency measure, not a prediction of an individual household’s electricity bill. Actual use, incoming water temperature and the selected configuration affect operating results.
Lowboy dimensions and replacement access
- A — floor to top of heater: 32 3/8 inches.
- B — jacket diameter: 24 inches; excludes the supplied blanket.
- C — floor to water connections: 34 5/8 inches.
- E — floor to standard side T&P connection: 23 9/16 inches. The optional top location is 34 5/8 inches.
- D — water-connection center spacing: 8 inches; G — water connections: 3/4-inch NPT.
- Approximate shipping weight: 140 pounds, not the filled operating weight.
A cabinet wide enough for a 24-inch tank may still be too narrow for this model as installed. Review the full blanket envelope, drain pan, access panels and plumbing before ordering. The blanket is part of the required installation, so choosing a smaller bare jacket is not a reason to omit it.
RE240L6 requires its supplied 2-inch insulation blanket. The specification dimensions exclude that blanket. Adding 2 inches on each side of the 24-inch jacket gives an approximate 28-inch body width for planning; this is a calculation, not a certified finished dimension. The blanket supplement calls for a pan at least 6 inches larger than the pre-blanket heater diameter in length and width, giving 30 inches for this model before other project requirements are considered.
The blanket must not be compressed to force a fit. Installation must preserve the required access and openings described in the supplement. Do not add an assumed amount to the published height and call it a verified overall dimension; review the supplied blanket arrangement, fittings and clearances at the actual site.
Compare the closest current models
The RE240LN6 has a 24 1/2-inch jacket without the supplied-blanket designation, 34 gallons DOE storage and a 45-gallon first-hour rating. Its heater top is 32 1/16 inches high, compared with 32 3/8 here. RE240L6 provides slightly more rated storage and a higher first-hour figure, but its blanket changes the width comparison. The larger RE250L6 also uses a supplied blanket and needs still more room.
Lowboys are a separate family from the short upright electrics. For example, the RE330S6 short upright is 46 11/16 inches to the heater top. Compare the actual body and connection heights instead of treating the words “short” and “lowboy” as interchangeable.
Electrical configuration and recovery
This guide uses the sheet’s standard 240V, single-phase configuration with two 4,500W elements operating non-simultaneously. One element operates at a time, so this is not a standard 9,000W simultaneous load. The recovery table gives 21 gallons per hour at a 90°F temperature rise, or 19 gallons per hour at a 100°F rise, for 4,500W operation.
Recovery describes reheating at a specified temperature rise; it is separate from stored volume and first-hour delivery. Other voltage, input and wiring options have model-specific restrictions. WHE checks the full nameplate, supply and circuit before installation. An available factory wattage option is not permission to increase input on an existing circuit.
Installation and ongoing service
Standard side T&P placement is the basis of this guide; the sheet also lists an optional top location. WHE reviews the supporting surface, leak-management arrangement, relief discharge, shutoff access and thermal-expansion provisions where the water supply is closed. Adequate room to reach the element covers, drain and anode matters after the initial installation as well.
The family includes a protective anode and a sediment-control system. Those features do not make the heater maintenance-free; inspection and service should follow the instructions supplied with the equipment. Keep the model, serial number and installation record together. Have electrical diagnosis and internal service performed by a qualified professional; recurring trips, leaks or a change in delivery deserve assessment.
Six-year model and warranty terms
The final 6 identifies the six-year tank version. 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. Removal, installation and associated repair or replacement costs are excluded, subject to applicable law. Check the certificate supplied with the heater and confirm eligibility using the complete model and serial number.

Bradford White RE240L6 FAQs
Is RE240L6 a 40-gallon tank?
The current row lists 38 gallons nominal and 35 gallons DOE rated storage. It also lists a 49-gallon first-hour rating and 0.91 UEF. Those values describe the current model more accurately than a rounded size label.
How much width does the RE240L6 blanket add?
The supplied blanket is 2 inches thick. Adding it on both sides of the 24-inch jacket gives an approximate 28-inch body width for planning. This is a calculation, not a certified finished dimension, and the pan and service space require additional allowance.
Do both 4,500W elements operate at once?
The specification’s standard arrangement is 240V, single-phase and non-simultaneous, with two 4,500W elements. The controls energize one at a time. Confirm the supplied nameplate; other factory configurations require separate verification.
Does the six-year warranty include installation labor?
The 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 check whether RE240L6 fits my home?
Yes. Send the existing model label, a wide photo of the installation, available opening measurements and your hot-water concerns. WHE checks fit, demand and the installation scope in Palm Beach Gardens, Jupiter and nearby Palm Beach County communities. Availability and scheduling are confirmed for the project.
