Factors that Impact Cost

While a tankless water heater from Takagi seems like a no-brainer, thanks to the affordable price tag, your final expenses will be greater than just the cost of the unit. After all, what good is a tankless water heater if it isn’t properly installed?

Check out the factors that can add up when installing a new tankless water heater so you can temper expectations heading into the installation process.

• Installation
• Venting
• Water lines
• Gas lines

Installation

Installation is a necessary blow to your budget. There’s no getting around it, and it’s always best not to cut corners during a major home upgrade since safety is a concern. While there may be unforeseen expenses during installation, it’s best to get the job done right the first time.

While the top-end Takagi model may max out at just $1,800, installation costs can raise the cost to between $4,700 and $8,000. It’s a pretty broad range, but there’s a reason for that wide gap. Some installers offer base and premium installation.

With a base installation, you’ll likely get the usual water connections, gas connections, new isolation valves, and the unit itself included in the installation cost. Companies that offer premium installation typically include an expansion tank, a neutralizer, and water treatment for your tankless water heater to run at its best.

Depending on which route you take, you can expect to land near the top or bottom of the range. But a base installation can reach up to $6,200, while a premium installation might start at $5,000.

Aside from the initial installation costs, there are a few other considerations to factor in before making your move on a Takagi tankless water heater.

Venting

Proper venting is a must when installing a tankless water heater, but your existing venting might not cut it. This is where you can see additional costs in the way of new or revamped venting.

If your venting needs menial work, you can expect an added investment of about $395. But the more venting needed, the higher the cost. If your home requires more venting work, then it tracks that the cost would go up accordingly.

There are a couple of other factors to keep in mind before scheduling an installation. Your water heater’s location also plays into budgeting for venting costs. In some cases, specific types of venting might be required to get the job done right, which will also affect cost.

You may not incur the same costs as the next home, but calculating some extra padding to your budget is always a wise move so that these types of adjustments don’t hit quite as hard when they arise.

Water Lines

A technician may have to replace your water lines if they’re not in great shape. This is done to ensure your tankless water heater is installed safely and in a way that will help it last. You’ll need new lines put in if you plan on relocating your water heater, though.
Fixing up lines or installing new ones will run you between $395 to $995. While the low end of this project isn’t so bad, it can quickly turn into something a bit more involved, leaving you at the higher end of the scale when it comes to additional costs. It’s wise to budget on the higher end just to play it safe.

Gas Lines

Your gas lines are often out of sight and out of mind, making their condition a bit of a mystery heading into the installation process. You may not even know what size your lines are, which can add more to your installation cost.

While many homes have ½-inch gas lines, tankless water heaters require ¾-inch gas lines. If you end up with ½-inch connections, then they’ll likely need to be swapped out, leading to a bump to your bill.

There’s always the chance that your gas lines do fit, but their condition is also of consideration. If your gas lines aren’t in good working order, they’ll have to be replaced.

Swapping out gas lines is a more expensive endeavor and can cost up to around $3,900. This repair is tough to budget for since most homeowners will be crossing their fingers that their lines are in order. Still, budgeting for this additional expense will help you avoid surprises during the installation.
