How Much Does a Noritz Tankless Water Heater Cost?

There’s no great way to answer this question since Noritz offers a range of products. But you’re typically looking at $1,200 to $2,300 for a residential Noritz tankless water heater alone. 

Depending on your home size, demand, and the number of bathrooms, the cost of a Noritz tankless water heater will scale. To get a clear idea of what you might need, take these 3 steps to determine which size of tankless water heater is right for you

While you can get a great idea of what to expect in terms of price by determining the size of the tankless water heater you’ll need, there are still several factors that can increase the overall cost, mainly installation. 


Factors That Impact Cost

So, you’re committed to going all-in on a tankless water heater but aren’t sure what surprises might be in store for you. Well, there can be a few, including installation. Beyond installation, some of these modifications can cost between $395 to $3,900.

Factors that impact cost include:

  • Installation
  • Venting
  • Water lines
  • Gas lines



Installation is an inevitable expense when choosing a major home upgrade, and Noritz tankless water heaters are no exception. 

While the tankless unit itself may come in at the top end of $2,300, adding installation can carry the final cost to between $4,700 and $8,300. That’s quite the range, but some companies offer both base and premium installation, which extends the possible cost quite a bit. 

While a basic installation will get you all the water connections, gas connections, new isolation valves, and the unit, a premium installation adds a bit more value. Some installers include an expansion tank, a neutralizer, and water treatment for your tankless water heater. 

But aside from the installation cost, you may run into a couple of other expenses during the process. 



Venting is one of those installation pitfalls that can cost you a little or a lot, depending on the depth of modifications. On the low end, adjusting venting can cost about $395. 

But venting can get complicated depending on the state of the existing system. In this case, the math is pretty simple. Some homes may require less venting than others. The longer the venting, the higher the cost. 

Where your water heater is located can also have a bearing on the cost of venting. In some cases, the type of venting needed to complete the installation may be different than a more standard installation. 


Water Lines

If your water lines are on the older side, a technician will likely need to replace them to ensure everything is above board. Additionally, if you choose to relocate your water heater, you’ll likely have to run more water lines, which will bump the cost up further. 

Fixing up or running new water lines to be in working order can run from about the $395 mark to around $995. While this isn’t the steepest issue to remedy, the state of your water lines is something to factor into your budget if you want to play things safe.


Gas Lines

Tankless water heaters require ¾-inch gas lines, but many homes have hookups with ½ lines. This means that these gas lines may have to be replaced, adding an unexpected cost to the initial installation. 

Some gas lines may be old and in need of replacing, even if they fit correctly. You’re looking at a similar additional cost in this case as well. 

On the high end, revamped gas lines could cost up to $3,900
