About the GE Profile PF50S10FPY01
This guide covers the GE Profile PF50S10FPY01, a 50-gallon 120-volt heat pump water heater on the ENERGY STAR certified list.
It stores 50 gallons and has a first-hour rating of 59 gallons — the amount of hot water it can supply in one busy hour starting with a full tank. The DOE classifies it in the medium usage draw pattern, so its efficiency rating assumes about 55 gallons of hot water a day.
Its UEF of 3.20 means it moves about 3.2 units of heat into the water for every unit of electricity, by drawing heat from the surrounding air. A standard electric-resistance tank scores roughly 0.9 to 0.95.
This 120-volt model plugs into a standard household receptacle, which can make it a practical replacement for a gas water heater without new 240-volt wiring. The compressor operates down to 35 °F; outside that range the unit relies on any backup heat it has. Refrigerant: R-1234yf. The listed sound level is 41 dBA. It is connected-capable (Wi-Fi, CTA-2045, Bluetooth) and supports CTA-2045-A and CTA-2045-B demand-response communication, so it can take part in utility programs that shift water heating to off-peak hours.

Safety information
- Set the water heater to about 120 °F (49 °C). Water at 140 °F can cause a serious burn in a few seconds; at 120 °F it takes several minutes. Homes with young children or older adults benefit from anti-scald valves at tubs and showers.
- The temperature and pressure (T&P) relief valve protects the tank from bursting. Never cap, plug or remove it, and keep its discharge pipe running full size to within about 6 in. of the floor or to an approved drain.
- Installation should be done by a licensed plumber (and electrician or gas fitter where required). Most jurisdictions require a permit.
- Turn off the breaker before removing any cover. Never switch on power to an electric water heater until the tank is completely full — an element energized in air burns out in seconds.
- Where local code requires it (for example, in seismic zones), secure the tank to the wall with approved strapping.
Installation and first-time setup
Use this checklist when planning the installation of the GE Profile PF50S10FPY01 and when reviewing the finished job with your installer.
- Choose a space with enough air
Integrated heat pump water heaters need a large volume of air or ducting — often around 700–1,000 cubic feet, but follow your manual. Basements, garages and large utility rooms work well; a closet usually needs louvered doors or ducts. The compressor stops below 35 °F, so very cold spaces push the unit onto backup heat.
- Leave service clearance
Keep space above and around the unit for airflow and for removing the air filter. The tank is 48.1 in. tall and 18.5 in. in diameter, so check ceiling height and doorways before delivery.
- Condensate drain
The evaporator removes moisture from the air. Route the condensate line to a floor drain or condensate pump; the amount can be significant in humid weather.
- Electrical supply
This model plugs into a 120 V receptacle and draws up to 7.5 A. Some 120 V models need a dedicated circuit and others are designed to share one — follow the installation manual.
- Plumbing connections
Use dielectric fittings where dissimilar metals meet, install a shut-off valve on the cold inlet, and pipe the relief valve discharge to an approved location. Add an expansion tank if the supply has a check valve or pressure-reducing valve.
- Fill and purge before start-up
Fill the tank completely and run a hot tap until water flows steadily, so no air remains, before turning on power. Then set the temperature and check every joint for leaks.
Using your water heater
Operating modes
Most heat pump water heaters offer an efficiency (heat pump only) mode, a hybrid or auto mode that adds backup heat when demand is high, a high-demand mode, and a vacation mode. Mode names differ by manufacturer, so check your manual. Use the most efficient mode that keeps up with your household, and switch to hybrid or high demand only when guests are staying.
Heat pump recovery is slower than an electric element. If you run short of hot water, raise the setpoint a few degrees with a mixing valve installed, or use hybrid mode during peak times rather than leaving the unit in resistance-only mode. When the surrounding air falls below 35 °F the compressor pauses.
Expect cool air from the unit's exhaust and a gentle fan and compressor hum. In summer the cooling and dehumidifying effect can be a bonus in a basement; in a heated space during winter it slightly increases the load on your heating system.
Saving hot water and energy
- Fix dripping hot-water taps promptly and use WaterSense showerheads and faucet aerators.
- Insulate the first several feet of hot and cold pipes at the heater.
- Wash laundry in cold water when possible.
- Enroll in your utility's demand-response program if one is available; this model's advanced load-up functions let it heat ahead of peak periods while keeping hot water available.
Care and maintenance
| When | What to do |
|---|---|
| Every year | Test the T&P relief valve by lifting its lever briefly with a bucket under the discharge pipe; if it does not reseat and stop dripping, have it replaced. |
| Every year | Drain a few gallons from the tank drain valve, or flush it fully, to remove sediment — more often in hard-water areas. |
| Every 2–3 years | Have the anode rod inspected and replaced when it is heavily corroded; this is the main defense against tank corrosion. (Some models use a powered anode — follow the manual.) |
| Every 1–3 months | Clean the air filter on the heat pump section as the manual directs, and check that the condensate drain flows freely. |
Troubleshooting
Check these common causes before calling for service.
| Problem | Possible cause | What to try |
|---|---|---|
| Not enough hot water | Efficiency mode cannot keep up with demand; setpoint low; very cold air around the unit. | Switch to hybrid or high-demand mode temporarily; raise the setpoint slightly with a mixing valve; improve air supply to the unit. |
| Unit seems to run constantly | Normal for heat pump recovery, which is slower than an element; dirty air filter. | Clean the filter. Long run times at low power are expected. |
| Water around the base | Blocked condensate line; leaking fitting; relief valve discharge. | Clear the condensate drain and check fittings; a leaking tank must be replaced. |
| Fault or alert on the display | Sensor, airflow or element fault detected by the controls. | Note the code and look it up in the code table in your manufacturer's manual. |
| Rotten-egg smell in hot water | Bacteria reacting with the anode rod or water chemistry. | Flush the tank; a plumber can replace the anode with a different alloy or treat the water. |
| Relief valve dripping or discharging | Excess pressure from thermal expansion; failing valve; temperature set too high. | Have the pressure checked and an expansion tank added if needed; replace a faulty valve. Never plug it. |
Energy use and running costs
The GE Profile PF50S10FPY01 is estimated to use 1,015 kWh per year, about $173 a year ($14.38 a month) at $0.17 per kWh.
A standard electric-resistance tank with a UEF of about 0.92 would need roughly 3,530 kWh to deliver the same hot water — about $428 more per year.
These estimates come from the DOE test, which assumes 55 gallons of hot water a day heated from 58 °F to 125 °F; your use will differ. Heat pump performance also depends on the temperature of the air around the unit and on how often backup heat runs.
Frequently asked questions
How much hot water does the GE Profile PF50S10FPY01 provide?
It has a 50-gallon tank and a first-hour rating of 59 gallons, which is the best guide to how it handles a busy morning.
What is the UEF of the GE Profile PF50S10FPY01?
Its Uniform Energy Factor is 3.20, measured in the DOE medium usage draw pattern. Values above 1 are possible because a heat pump moves heat from the air rather than generating it.
