Tankless water heaters have become a go-to option for homeowners looking to cut energy costs and enjoy endless hot water.

These systems work differently, require specific know-how, and perform best when installed or serviced by a team that knows what they’re doing, like Pesky Root Plumbing.

Our Approach to Water Heater Installation & Repair

Not every plumbing company handles tankless systems the right way—and not all homes are ready for one without a little prep. Pesky Root Plumbing takes the time to assess your plumbing layout, gas or electrical capacity, and hot water usage before making recommendations. If your home’s a good fit, we’ll install a system that meets your needs without overloading your infrastructure or your budget.

What we offer:

  • Tankless water heater installation
  • Tankless water heater repair
  • Routine maintenance and descaling
  • System flushes and performance checks
  • Gas line upgrades for tankless compatibility
  • Troubleshooting error codes and heating delays

If you already have a tankless unit and it’s underperforming—or giving you frequent errors—we’ll track down the issue and get it running properly again. No guessing, no overcharging, and no unnecessary replacement pitches.

Why Choose a Tankless Water Heater?

Tankless systems aren’t just trendy—they’re smart. They heat water on demand, which means you’re not paying to keep 40 or 50 gallons of water hot all day. For many homeowners, that translates to lower monthly bills, longer system lifespan, and less space taken up in the utility room or garage.

Here’s what makes tankless water heaters appealing:

  • Endless hot water – Provide consistent hot water for multiple showers, appliances, and faucets running simultaneously without running out.
  • Save space – Tankless units are compact and mountable, freeing up valuable space in your utility area compared to bulky traditional tanks.
  • Energy efficiency – Heat water only when you need it, reducing energy waste and lowering utility bills over time.
  • Long lifespan – With proper maintenance, tankless water heaters can last up to 20 years, outpacing traditional models.

If high energy bills, limited hot water, or outdated equipment frustrate you, transitioning to a tankless water heater could be a game-changer for your household’s comfort and efficiency.
