Switching to the RE2H50S
From a standard electric tank
Same voltage (240V). Verify breaker size matches unit requirements (30A typical).
Taller unit (59.1875"). Measure overhead clearance.
Condensate drain needed. Floor drain or condensate pump.
Air space needed around the unit for heat exchange.
Fewest install changes of any upgrade path. Scope depends on existing wiring, clearances, and condensate routing.
From a gas tank
New 240V/30A circuit required. Hire an electrician.
Gas line capped. No more gas bill for hot water.
Existing flue/vent can be removed.
Condensate drain needed.
Two trades needed (plumber + electrician).
From an older heat pump
Same electrical. Same condensate drain.
Check height. This unit is 59.1875" tall.
Standard water connections.
Similar installation profile. Verify dimensions, clearances, and condensate routing match your existing setup.
Height, electrical service, condensate, and noise. These are the four things that determine whether a heat pump fits your space and your quote.

Safety and installation warnings
These warnings apply to this water heater type. Always follow the manufacturer's installation instructions and local building codes. Hire a licensed professional for installation.
T&P relief valve. Every tank-type water heater has a temperature and pressure relief (T&P) valve. This is a critical safety device that prevents tank rupture by releasing water if temperature exceeds 210°F or pressure exceeds 150 PSI. The discharge pipe must run to within 6 inches of the floor or to an exterior drain. Never cap or plug the T&P valve. Test it annually.
Scald prevention. The recommended maximum water temperature is 120°F to prevent scalding. Higher temperatures (130-140°F) reduce Legionella bacteria risk but require a thermostatic mixing valve at the outlet to deliver safe temperatures at fixtures. Some jurisdictions require mixing valves when the tank is set above 120°F.
Cold-climate performance. Below 35°F ambient air temperature, the heat pump compressor shuts off and the unit falls back to electric resistance heating at much lower efficiency. The rated UEF assumes DOE test conditions (67°F ambient, 58°F inlet water). In cold climates or unconditioned spaces (garages, unfinished basements), actual annual efficiency will be lower than the rated UEF, and energy costs will be higher than the estimates shown above.
Cold exhaust air. Heat pump water heaters extract heat from surrounding air and exhaust cold, dehumidified air. Do not install in a space that is already difficult to heat. The unit will lower the room temperature by several degrees, which may increase HVAC costs or reduce heat pump efficiency in winter.
Common install considerations for heat pump units
What is required depends on your existing installation, local code, and installer preference.

Starting May 2029, new federal standards require heat pump technology for electric water heaters over 35 gallons. Electric tanks 35 gal and under can still use resistance elements. Every heat pump on this list already exceeds the future standard. Read the full DOE 2029 analysis
Common questions about the Bradford White RE2H50S
From manufacturer specs, EIA energy data, and DOE regulations.
How much does the RE2H50S cost to run per year?
~$170/yr at the U.S. average electricity rate. That is roughly $466/yr less than a standard electric tank.
How much hot water does the RE2H50S deliver?
65 gallons in the first hour from a 45-gallon tank. Suitable for a household of 1 to 3 people at medium draw.
Will the RE2H50S fit in my space?
59.1875" tall, 21.75" wide, 21.75" deep. Measure your space including clearances before ordering.
What electrical circuit does the RE2H50S need?
240V, 30A dedicated circuit. Check your electrical panel before installation.
Does the RE2H50S work in cold climates?
The heat pump operates down to 35°F ambient temperature. Below that, it switches to standard electric resistance mode, losing the efficiency advantage. In cold climates, install inside the heated building envelope, not in an unheated garage.
What warranty does the RE2H50S come with?
10-year tank warranty. Register with Bradford White after installation to activate full coverage.
Is the RE2H50S eligible for rebates?
ENERGY STAR certified heat pump water heater. The federal tax credit (IRA Section 25C, up to $2,000) expired December 31, 2025. State and utility rebates may still apply depending on your location.
Is this unit future-proof under the 2029 DOE standards?
Yes. Starting May 2029, electric water heaters over 35 gallons must use heat pump technology. This unit already exceeds that standard.
