Water heater installation

Have you noticed that your water heater leaks or isn’t at its best for other reasons? You may have to call for professional service to help you out and learn water heater installation costs. 

Or, if you have just moved in and the water heater is not yet installed, this urgent installation will also have to be organized soon. Gas water heaters or electric ones? Call “1 877 GO LOWES” for professional advice. 

A water heater is an essential home appliance. They come in two main styles: tank and tankless water heaters.

Tank water heater

A tank water heater stores hot water in a large tank; it’s 30 to 80 gallons on average (you’ll see mostly 50 gallon tank). They make more than 90 percent of water heaters installed in the US.

When it comes to its size, buy a water heater that fits the needs of the household. Buying a unit that’s too large will result in high prices on energy bills over the entire lifespan of the heater. 

Tankless water heater

Tankless water heaters have tripled cost, so they are rarer in population. 

They’re also more challenging to install and cost more when it comes to installation labor.

Red flags to replace heater before it fails

If you notice these things happening, it’s high time for a replacement project of your 50 gallon tank heater before it fails.

Water isn’t hot enough

If you’ve noticed that the water coming from the heater isn’t as hot as it used to be, there might be a problem with the central heating element.

In this case, it’s time to buy a new water heater.

High energy bills

If you’ve recently received that unusually high bill for energy, it’s another sign that your heater is inefficient. 

Around four hours a day is a typical time that water heaters run. 

If it’s running more than that, your hot water heater may be calling for a replacement. 

Rusty water or metallic taste

Water coming out of the tap should be clear and transparent. 

If you see that your tap water has a rusty look or metallic taste, the anode inside the heater has probably failed. 

Consider replacing a piece or replace a water heater. 

Loud noises

Things no one should hear coming from their water heaters are pops, cracks, and bangs. 

With the hot water heater producer extended warranty, maybe you can resolve the issue before the heater breaks completely. 


Leaking in the water heater shows that there is a failure. 

We’re getting you some help with this issue later in the article. 


Expect your traditional water heater to last about 15 and tankless water heater more than 20 years. 

After that age, we strongly suggest taking the hot water heater replacement project seriously. 

So if your water heater is 20 years old, head to Lowe’s or Home Depot to check out the current water heaters market. 

What are the causes of water heater leaking?

Why does a water heater leak in the first place?

The need to install a new water heater may come because the old one started to leak. 

What are the possible causes of such a state of affairs?

Causes of water heater leaks include:


After a period of frequent use, sediment buildup can cause corrosion. 

There is also a danger of crackings and holes in the tank’s bottom for the same reason. 

It’s high time to consider water heater replacement if these issues occur in your water heater (and its year warranty is over).

Broken drain valves

If you notice water leaks at the bottom of the tank, the problem may be broken drain valves. 

This situation doesn’t require the whole heater replacement. 

It’s just a matter of reaching out to professionals and replacing the broken drain valve.

Voila! The problem is fixed almost for free!

Loose water line connections

Similarly, as with drain valves, water line connections are not a big issue to deal with. You don’t have to replace the entire gas or electric water heater. 

Casual wear and tear can loosen the inlet or outlet water lines and cause leaks. 

Tightening or replacing the loose, worn water lines of a heater will resolve the difficulty. 

Broken temperature/pressure valves

These are valves that monitor and regulate the temperature and pressure inside water heaters. 

They can cause water leaks from the sides of the water heater tank.

This issue will require the intervention of a plumber or other professional service. 

If you have a warranty, you may want to look for it to make the repair project cost more affordable.

What to do if my water heater is leaking?

One day, your hot water heater may start to leak. 

Yet, you’re not a plumber (unless you are), and you don’t know what to do next. 

Fortunately, we have a bunch of good tips (check House Rituals). 

If you see your heater leaking, take these three steps:

Cut the power 

When you find a hot water leak in the water heater in your house, cut off the electricity supply.

  • Gas water heater: Find a thermostat with a little knob with three settings: ON, OFF, and PILOT. Switch it to OFF or PILOT to shut off the gas. 
  • Electric water heater: Go to your breaker panel and find a “water heater.” Turn it off to cut the power.

Shut off the water

Find the cold water line leading to your water heater and shut it off by turning a valve (at the end of the line) to the right. 

Drain the water tank

If you have a tank (in a traditional water heater), drain it.

Important: There are also tankless water heaters. This tip doesn’t refer to them. 

How to drain the heater tank?

  • Find the drain valve near the bottom and attach a garden hose to it.
  • Run the hose to a floor drain, bidet, washbasin, or sump pit.
  • Open the valve (it may look like an ordinary spigot in an old water heater or a drain stem with a slot for a screwdriver in modern type). 

If the water doesn’t flow well (or at all), there might be a vacuum in the water heater.

What to do with the vacuum?

To break the vacuum, open any hot water faucet in your home. 

Long (physical) story short, it will let air into the water tank and allow it to drain more easily. 

It will take about an hour to drain the tank.

How much does it cost to install a new water heater?

If a new water heater installation is necessary, you may be wondering what the cost of this adventure is. How much it costs to have a Lowe’s professional service install it in your house?

And also, if you want to replace a water heater that you have at home and buy a new one at Lowes or Home Depot Store, is there any extra cost for water heater installation labor?

We’ve given an attentive look at Lowe’s offers.

It appears that labor cost is almost as high as the cost of a new water heater itself. 

Let’s get to the practical part. How much does the water heater installation cost?

Lowe’s cost to install gas and electric water heaters

Lowe’s Companies, Inc, also known as Lowe’s, is a chain retail store focused on home improvement. They operate in the United States and Canada. 

First things first: Lowe’s is not going to install a new water heater in your house. Instead, Lowe’s offers to sell a water heater to you and then organize a water heater installation. 

The brand also offers water heater protection plans in the form of an extended warranty.

So Lowe’s will arrange an outsourced contractor, installer, or plumber to install a water heater in your house for an extra fee. 

It shouldn’t come as a surprise that Lowe’s gets a percentage in labor price at an agreed rate for the service job. 

So we can draw some systemic conclusions from this. An average Lowe’s contractor is willing to work for less than a plumber or other installers who have their own businesses apart. 

Knowing that seems to explain why we so often hear about the unexpectedly rising cost of having a water heater installed by Lowe’s contractor (when Lowes plumbers are just about to install the appliances in our homes). 

Be aware of the potential extra cost! Kindly refuse if you believe it’s going overboard. 

It’s likely that licensed installers outside the “Lowe’s zone” will do the job at a more fair price and without unnecessary extras. 

Important: The cost to install a water heater varies based on the individual needs of a customer. For a personalized quote, fill out the form on the Lowe’s website or call 1 877 GO LOWES.

Water heater installation costs

How much does Lowes take? What is a prices range?

The labor cost to install a hot water heater varies depending on many factors. 

We’re talking about 400-1500 dollars to install. So let’s say that on 50 gallons water heater, a homeowner will have costs of 1,000 dollars on average.  

When it comes to installing traditional tank water heaters, Lowe’s charges 325 dollars for basic installation. 

Besides basic installation costs, there are:

  • inspection, 
  • quote or estimate cost, 
  • new piping, 
  • delivery cost, and
  • disposal;  

Lowe’s will install the water heater bought from them for $275 ($325 for power vent) basic installation fee. 

Before putting in the installation work, Lowes sends an installer to your home to check the conditions for the installation and give a quote or estimate. For this part, Lowes charges 40 dollars fee. 

You will probably need additional piping to complete the installation of the heater. And it’s another cost. According to Lowe’s sales representatives, new white piping (if former have black piping) is a cost of about $200.

For Lowe’s job delivery of the water heater to your home, expect a charge of an extra $75 fee. 

If you want to save, consider renting a car for an hour. Lowes has van or vehicle renting services so that you can deliver your heater unit home by yourself. The price is about 20 dollars. 

Typically, to send the unit to your home, Lowes charge 75 dollars, so with renting, you’re saving 50 dollars on delivery. 

Last but not least, the disposal cost is $50.

Other factors that affect cost can include permit fees and carpentry work, adding $50 to $1,500 or more to the overall project cost.

What about tankless water heaters? How much does a tankless water heater average cost with installation? 

A certain advantage of this type is that you’ll never experience any unexpected cold showers with a tankless water heater. 

Yet, the average cost of a tankless water heater (with installation) is around $3,000.

Frequently Asked Questions

It takes about 1 to 1.5 hours to conduct a water heater installation by a licensed professional. Yet, if you have an old hot water heater in place, it will also call for 1 to 1.5 hours to remove it. So, in total, the installation will take 2-3 hours.
Given it doesn't seem too complicated, you may feel the urge to do the installation yourself. It seems that it comes with extra savings on installation costs. However, consider that not being an experienced installation specialist, you never know what you can come across during the installation process. Therefore, we don't recommend conducting a water heater installation by yourself. Instead, you have a heater installed by a qualified plumber to ensure the full professionalism of the process.
The "life expectancy" differs depending on the type. For example, a gallon tank water heater should last eight to 15 years; a tankless unit should last at least 20 years.
