Hey, Mike here 👋
If you’re standing next to a brand-new 50 or 60-gallon electric water heater from The Furnace Outlet thinking “Now what?” — relax. I’ve got your back.
This blog is for folks who want to install it themselves, fix it when things go sideways, and avoid calling a plumber every time the water turns cold. I’ll show you how to:
-
Prep and install your electric heater safely 🔧
-
Connect the wiring and water lines
-
Solve common problems (like no hot water)
-
Flush the tank and extend its life
And I’ll toss in a few dad jokes and emojis along the way to keep it lively. Ready to dive in? Let’s do this.
Why 50–60 Gallon Electric Water Heaters Are a Sweet Spot
You’re not buying this thing for fun—you need dependable hot water. And a 50 to 60-gallon tank gives you just that. It’s the ideal size for 3–5 people, whether you’ve got teens hogging the shower or a mountain of laundry to wash.
Electric models are simpler than gas heaters: no pilot lights, no combustion air, and you can install them just about anywhere that’s dry and up to code.
And starting in 2025, efficiency standards got a bump, so if you're upgrading now, you're doing your future self (and your utility bill) a favor. According to the U.S. Department of Energy, the new rules could save homeowners over $7.6 billion collectively over the next 30 years. Not bad for a water tank!
Tools & Materials Checklist 🔨
Before you yank out the old one, grab:
-
Voltage tester
-
10/2 NM cable (or armored if required)
-
30-amp double pole breaker
-
Pipe wrench and channel locks
-
Teflon tape
-
Dielectric nipples or flex hoses
-
Drain pan (code required in most areas)
-
Expansion tank (check your local code)
-
Multimeter for troubleshooting
And make sure you’ve pulled a permit if your city requires it. If in doubt, call the building department.
Step-by-Step: Installing a 50–60 Gallon Electric Water Heater
1. Shut It All Down
Turn off power at the main panel. Don’t skip this. Test the wires at the heater terminals with your voltage tester to make sure you’re not about to light yourself up.
Shut off the cold water supply and hook up a hose to the drain valve. Open the T&P valve and let it drain fully.
2. Remove the Old Unit
Disconnect water lines. Cut the power wires if needed, but leave enough length to splice onto later. Use gloves—those old tanks can be gross.
3. Position the New Heater
Set the new unit in the drain pan. You want it close to the same spot, especially if your electrical wire is staying put. Install the T&P relief valve and make sure it’s piped down to the floor.
If your water pressure exceeds 80 psi, or you have a backflow preventer, install an expansion tank on the cold water line.
4. Hook Up Water Connections
Use Teflon tape on threads, and install flex connectors or sweat copper lines if you’re comfortable with soldering. Don’t over-tighten!
Make sure both cold inlet and hot outlet are secure. Open the cold valve and fill the tank completely before flipping the power back on.
5. Wiring the Electrical Safely
This is where you need to pay attention. If you’re not confident, call a licensed electrician. That said, it’s not rocket science. Here’s how:
-
Use 10/2 wire with a ground. The two conductors will be your hots (black and white). Mark the white with black tape to indicate it's hot.
-
Connect black-to-black, white-to-white, and green-to-ground.
-
Double check with a multimeter before turning the breaker on.

First Startup Tips
Once the tank is full (open the hot side of a faucet and let it run till no air spits out), close it and switch the breaker ON.
You should hear the elements click on. Give it a couple hours and check if the water gets hot.
Set the thermostats to 120°F—hot enough for comfort and efficiency, but not hot enough to scald.
Troubleshooting Common Issues 🧰
No Hot Water?
First, check the breaker. If that’s fine, hit the reset button on the upper thermostat—it’s a red button under the access panel.
Still no luck? It might be a burned-out upper element. Test it with a multimeter and replace it if needed.
A great step-by-step diagnostic can be found on Plumb University, including diagrams for multimeter testing.
Not Enough Hot Water?
That’s usually the lower element. It kicks in once the top is satisfied, so if it’s dead, you’ll run out of hot water quick.
Could also be sediment buildup. That’s especially true if you hear rumbling or popping—a sign the tank needs flushing.
Water Too Hot?
Thermostats set too high. Turn it down. If that doesn’t work, your thermostats may be faulty and stuck “on.” Replace both upper and lower if needed.
Breaker Keeps Tripping?
You likely have a shorted element or wire. That’s serious. Don’t just keep resetting it—test it or call a pro.
For signs of dangerous conditions, HomeTips has a thorough safety checklist worth reading.
Maintenance Musts to Keep It Running Strong 🛠️
Just like your truck needs an oil change, your water heater needs some love.
Flush It Once a Year
Drain a few gallons every year to get rid of sediment. In hard water areas, do this twice a year. It helps your elements last longer and keeps heat transfer efficient.
Check the Anode Rod
Every 2–3 years, check or replace the anode rod. It sacrifices itself to protect the tank from corrosion. If it’s down to a wire, it’s done its job.
Test the T&P Valve
Lift the lever once a year and let it snap shut. If it dribbles or doesn’t close, replace it.
