Factors that Impact Cost

A tankless water heater is useless on its own. This means you’ll have to navigate the installation process to get a return on your investment. But it isn’t just installation that can increase the cost of a Navien tankless water heater.

Factors that impact cost are:

• Installation
• Venting
• Water lines
• Gas lines

Here are a couple of things to keep in mind before going all-in on a Navien tankless water heater.

Installation

There’s no getting around installation costs for any major home upgrade.

Sure, the top-end cost of a Navien tankless water heater is around $2,300, but installation costs can easily inflate your investment closer to between $4,700-$8,300. You might think this is a pretty big range, and you’re right, but this includes installers with different installation tiers.

Some companies provide basic and premium installation packages. While you’ll get the standard water connections, gas connections, new isolation valves, and the unit, premium installations can bake in more long-term value.

Premium installations often add in items like an expansion tank, a neutralizer, and water treatment to keep your tankless water heater running at its peak.

Looking past the initial installation cost, a few things can stack up during the installation process.

Venting

On the low end, adjustments to your home’s existing venting or completely replacing it can cost about $395. Venting can get pricy, depending on the situation, though.

Basically, the more venting, the more expensive the installation. For instance, a foot of venting is going to be cheaper than five feet of venting. So, if your home requires more venting, you can expect an additional cost here.

Additionally, your water heater’s location plays a role here. And in other cases, some factors can necessitate a specific type of venting that differs from a standard installation. These are just a couple of examples of what you might run into.

Some homes don’t require as much as others, but it’s always best to play it safe when budgeting a project.

Water Lines

Depending on the state of your water lines, a technician may need to replace them to get your tankless water heater installed safely. But if you choose to relocate your water heater, you’ll certainly be seeing some additions to your final bill since you’ll need some new water lines.

To run new lines or fix up older ones, you could be looking at an additional $395 to $995. What may start as a somewhat modest investment can quickly work its way up to feeling like a weightier cost. This is another factor you’ll want to consider while heading into the installation process.

Gas Lines

From the outset of the installation process, you might think your gas lines are up to snuff. But the reality of the situation is that many homes have gas lines that are incompatible with tankless water heaters.

Many homes feature ½-inch gas lines, but tankless water heaters often require ¾-inch gas lines. If this is the case with your home, then they’ll need to be swapped out, which will hand you a price bump.

Even if your gas lines fit correctly, their condition is also important. If your lines aren’t in good enough shape, you’ll need to have them replaced to ensure the safety of your household.

Replacing gas lines is one of the costlier pitfalls you may face. On the high end, you’re looking at around $3,900 to have them replaced.
