What Tankless Heater Installation Involves

Tankless heater installation isn't a one-to-one swap with a tank system. Gas tankless units typically require:

  • Venting sized specifically to the unit, which often differs from a tank's existing vent
  • Gas line capacity sufficient to fuel the unit's higher instantaneous demand
  • Correct sizing based on how many fixtures might run hot water at the same time

Our plumbers evaluate your home's existing gas line and venting before installation so the new unit is set up to perform at its rated capacity, not just installed and hoped for the best.

Gas Tankless Water Heater Installation

A&B Plumbing specializes in gas tankless water heater installation. We're a certified Navien Tankless dealer and service center and stock all parts for the Navien units we install, so if service is ever needed after installation, the parts are already on hand rather than backordered. A&B Plumbing also installs electric tankless units, though gas tankless installation, particularly Navien, is where most of our tankless work is concentrated.

Tankless Hot Water Heater Installation, Start to Finish

Tankless hot water heater installation with A&B Plumbing starts with confirming your household's or building's peak hot water demand, since that determines what size unit is actually needed. From there, our plumbers handle removal of the old unit if one exists, install and vent the new tankless system to code, and test it under load before finishing the job.

When Tankless Water Heater Replacement Makes Sense

Tankless water heater replacement is worth considering when:

  • Your current tank keeps running out of hot water during normal daily use
  • The tank is aging and you'd rather not replace it with another tank
  • You're trying to reclaim closet or utility room space a tank occupies
  • You want lower standby energy use compared to a tank that reheats water around the clock

Not every home is a good fit for tankless without some changes to venting or gas line capacity, which is something we assess before recommending a switch.

Tankless Installation FAQs

Do I need a gas line upgrade for tankless installation?

Sometimes. Gas tankless units draw more gas at peak demand than a tank system, and if your existing gas line wasn't sized for that, it may need to be upsized. We check this before quoting the installation, not after.

How much space does a tankless unit save compared to a tank?

A tankless unit mounts to a wall and takes up a fraction of the floor space a standing tank does, which is one of the main reasons homeowners switch when space is tight.

Can I install tankless in the same spot as my old tank?

Often, but not always. Tankless units vent differently than tanks, so the existing vent location doesn't always work without modification, which is something we evaluate on-site.
