How much does a replacement water heater cost?


Water heaters, as well as plumbing & HVAC equipment in general, have been battered with price increases for the last two years. What does this mean? Water heaters used to be a commodity, a plumbing job that was completed for $1,500-$2,000 all day long. Over the course of the last 24 months, water heaters and their required installation components have gone up in cost significantly which results in higher replacement water heater costs. The good news is a replacement water heater is still affordable and one of the most cost effective plumbing, HVAC or water well appliances or equipment in your home! 

The variables that impact the overall investment the most are:

    • Type of water heater
    • Size of water heater
    • Required code upgrades and necessary modifications to the existing system
    • Accessories (of course)

When budgeting for a replacement you can plan to spend between $1,200 and $7,000.

Water heater replacement & installation additional factors to keep in mind


  • Get the right size water heater for your home and your hot water needs

    Having the right sized water heater can make all the difference. When considering a new water heater, keep in mind how the way you use hot water in your home may change. Sometimes you’re able to get away with a smaller water heater and save money and sometimes it is a smart move to install a larger heater based on a growing family.

  • Water quality

    A major factor in the life expectancy of your new water heating system is the quality of the water that runs through it. Austin Plumbing, Heating & Air can test your water to make sure your new water heater is on the right path for a long life!

  • Water heater efficiency

    Water heaters come in many different types of efficiency. When looking at a new water heater, be sure to ask your plumber about all of the different options you have when it comes to efficiency.

  • How long do you plan to be in the home?

    The type of water heater you get and any accessories you choose with it will likely depend on how long you plan to be in the home. When deciding between tank or tankless or that tank booster kit, keep in mind how long you plan to enjoy the new water heater.

  • Permits

    Austin Plumbing, Heating & Air always pulls a permit when installing a replacement water heater. This means you’re insured that your new water heater was installed to code and it gives the inspector a chance to look at the existing water, gas, electric and exhaust and request any upgrades they see fit. This is the best way to keep your water heater safe, efficient, up to date and up to code!

Frequently Asked Questions

What Should I Look For In A Water Heater?

The most important factors in a water heater extend beyond the water heater equipment itself. Make sure when you invest in a replacement water heater you’re investing in a contractor that will stand behind it.

If I Buy My Own Water Heater, Will You Install It?

We will happily install an owner supplied water heater. However, we do not warranty the product nor provide repair services in the future.

Will Austin Plumbing, Heating & Air Haul Away The Old Water Heater?

Of course! Be weary of any plumber that would leave old equipment onsite for you to deal with.

Does Austin Plumbing, Heating & Air Pull A Water Heater Permit?

Yes we do. Not because we have to, but because we want to prove that the work we do is up to code.

What Is The Best Water Heater Brand?

We install more replacement water heaters than anyone else in Washington and Waukesha County, which means we see firsthand which brands of heaters are leaking and at what age they start leaking.

We don’t believe that one brand is “better” or lasts longer than another in the market. However, we’ve found that some brands offer much better support with technical assistance and local distribution, which is why it’s more important to choose a trusted repair and replacement company than the brand name on the water heater.

Is An Extended Water Heater Warranty Worth It When I Get A New Water Heater?

It depends. In most cases, the water heater is the exact same whether it comes with a 6-year, 9-year or 12-year warranty. Any money spent buying a 6-year heater versus a 12-year heater warranty is much more like insurance than investing in a better product.

Ultimately, you can decide what is right for you and your family, but most clients decide they are better off installing a unit with a 6-year warranty and joining our Austin Club membership over spending extra money on an extended warranty.

How Long Does It Take To Install A Replacement Water Heater?

Water heater replacements are typically a four hour job. Upgrades and conversions can take up to a day.

Common Water Heater Replacement Upgrades


Water Heater Drain Pan

A drain pan is a great way to prevent water damage should your water heater spring a leak. The time to install a drain pan is at the time of your water heater replacement. We carry several sizes of drain pans on our trucks.

Running Out Of Hot Water- Get A Tank Booster

At Austin, we know how to turn your 50 gallon water heater into a 70 gallon heater without the expense of upgrading the tank. Our tank booster kits can get you that extra shower and hot water your home needs.

Instant Hot Water At Any Faucet In The House

Sick of waiting for hot water in the morning? Our retrofit instant hot water system provides you hot water where you need it without opening up walls and major repiping.

Emergency Shut Off Valve & Alarm

When you can’t risk the damage a leaking water heater could cause, we have emergency leak detection systems that will turn off the water to your water heater the second a tank leak is detected, saving you thousands of dollars in damage.

Upgrade To Tankless

Tankless water heaters are the ultimate when it comes to efficiency and never ending hot water. Although some cons do exist, a tankless water heater is a popular upgrade for many homeowners in Southeastern Wisconsin.

Upgrade To A Heat Pump Water Heater

Don’t have gas to your home but want the most efficient water heater you can get? Consider upgrading your standard electric water heater to a heat pump water heater. With the current energy credits available, you can save thousands on the upfront cost and hundreds of dollars per year with a heat pump water heater.
