How Long Does It Really Take to Install a 50–60 Gallon Electric Water Heater? (Spoiler: Faster Than You Think)

Hey Hey, Homeowners! 👋💧

It’s Savvy Mavi here, back with another totally doable guide for those of you ready to roll up your sleeves and install (or replace) that big beautiful 50–60 gallon electric water heater. Maybe your old unit finally fizzled out, or maybe you’re leveling up your hot water game—either way, you’re asking:

"How long is this gonna take?"

Great question. Whether you’re DIY-ing or calling in a pro, this blog lays out everything you need to know about timing, expectations, and what can slow you down or speed you up.

Let’s get that hot water flowing, friend! 🚿⚡

 

Quick Answer: The Average Install Time ⏱️

• DIY Installation: 2 to 4 hours (if you’re comfortable with basic plumbing and electrical)

• Professional Installation: 1.5 to 3 hours (depending on complications and prep)

Of course, the devil’s in the details—and I’ve got alllll the details coming up.

 

Step-by-Step: What Goes Into a Water Heater Install?

Installing a 50–60 gallon electric unit might seem intimidating, but it’s really a series of smaller tasks bundled into one smooth operation. Here’s what’s on the to-do list:

1. Turn off power at the breaker

2. Shut off cold water supply

3. Drain and disconnect the old unit

4. Move it out of the way (they’re heavy—be careful!)

5. Position the new unit and make electrical and water connections

6. Fill the tank, bleed the air, and test connections

7. Flip the power back on and let it heat up

For a more detailed walk-through with photos, the folks at Hot Water Solutions have a seriously excellent visual guide. 👏

 

What Affects Install Time?

Let’s break down the stuff that adds minutes—or hours—to your install:

1. Your Experience Level

If this is your first time doing plumbing or electrical work, expect things to take longer. Not because it’s complicated—but because you’ll double-check everything (which you should).

2. Your Tools & Parts Are Ready

You don’t want to be halfway through and realize you’re missing a dielectric union, Teflon tape, or element wrench. Do a full supply check before you start.

3. Replacing vs. New Install

• Replacing an old unit in the same spot? Much faster.

• New install in a new location? You’ll be running new water and electric lines—add 1–2 hours (or more).

4. Drain Time

Older tanks can take 30–60 minutes to drain fully, especially if sediment buildup is high. This step alone is where most people get frustrated.

Tip: Open a hot water tap upstairs while draining to speed things up via air pressure break.

5. Electrical Complexity

Got a clean, dedicated 240V circuit? Cool. If not, or if the breaker needs upgrading, that’s an extra time chunk—and potentially a job for an electrician.

You can find wiring diagrams and circuit requirements on the manufacturer’s site—like this Rheem electric water heater install manual.

 

DIY Timeline: Let’s Map It Out

Here’s how your Saturday project might go if you’re a confident DIYer:

🧠 Total DIY time: 2.5 to 4 hours

Add time if:

• You're working in tight spaces

• There’s corrosion or a stubborn connection

• You're documenting the process for your Instagram followers 😉📸

 

Pro Timeline: What to Expect When Hiring Out

If you’ve got a plumber or HVAC tech coming out to install the unit, it’s usually done in 1.5 to 3 hours. That includes haul away (if requested), connection, and testing.

Most pros arrive with everything they need, but delays can happen if:

• Access to the install site is restricted

• Electrical panel issues pop up

• The unit you purchased isn’t compatible with your home's plumbing

• There’s a permit delay (yes, some places require one—even for replacements)

Real Talk: Can You Install It in an Hour?

In theory, yes. But only if:

• You’ve done it before

• Everything is prepped and compatible

• The old unit is already gone

• You’re not dealing with rust, corrosion, or surprises

But let’s be real. Most of us need more than an hour unless we’re calling in a favor from Cousin Louie the plumber.

So give yourself grace—and a little extra time.

 

Savvy Prep Tips to Speed Things Up 🧤

Want to make the install fly by? Do these things the day before:

1. Clear the install space so you’re not navigating around boxes, bikes, or laundry baskets.

2. Turn off the breaker if the tank isn’t in use (you’ll save some energy too).

3. Double-check your new unit’s fittings—some need adapters or a different drain pan size.

4. Read the install manual (even just once!) so you’re not guessing mid-process.

5. Have plumber’s tape, pipe dope, and towels nearby. You’ll thank me later.

You can even partially drain the old tank the night before to give yourself a head start.

 

When Install Time Gets Wild: Troubleshooting Delays 🧯

Here’s when things don’t go according to plan—and how to handle it:

• Drain valve clogged with sediment? Use a shop vac to create suction or gently poke it clear with a wire (carefully!).

• Rusty old plumbing? Be ready with a pipe wrench and patience—or schedule a pro.

• Breaker trips after install? Turn it off immediately and recheck wiring.

For troubleshooting help, I always recommend The Spruce’s troubleshooting guide—they keep it clear and beginner-friendly.

 

Is It Worth Doing Yourself?

Let’s break down some numbers:

• DIY install (with tools): ~$300–$600

• Pro install: ~$600–$1,200 depending on your area

If you're confident with plumbing and electric, and your setup is straightforward, DIY saves real money. But if you don’t have the right tools or feel unsure about the wiring? It’s worth every penny to hire it out.

Also—check with your local utility! Some offer rebates or free installs for ENERGY STAR® water heaters. A good resource is the DSIRE database for state-by-state energy incentives.
