Tankless Water Heater Repair & Installation in Charlotte, NC

Tankless water heaters heat water on demand rather than storing a full tank of heated water. For the right home, they can provide efficient operation, reduced standby energy loss, and a compact installation.
Pathmaker Plumbing provides tankless water heater repair, installation, maintenance, replacement, and tank-to-tankless conversion guidance throughout Charlotte, NC.
As an authorized Rinnai dealer and installer, we also provide professional installation and service for Rinnai tankless water heating systems.
Tankless is not automatically the right answer for every house. We look at hot water demand, existing utilities, installation conditions, and what you want from the system before recommending a conversion or replacement.
What Is Your Tankless Water Heater Telling You?
Tankless problems can involve the equipment, controls, utility supply, water flow, maintenance needs, or installation conditions. The symptom pattern helps narrow down where to look first.
No Hot Water Or Intermittent Heating
A tankless unit that does not heat consistently can have a control, ignition, flow, utility, or equipment problem that needs to be diagnosed before replacement is discussed.
Temperature Changes During Use
Unexpected temperature changes may involve flow conditions, demand, system performance, controls, or another issue affecting how the unit responds while water is being used.
System Cannot Keep Up With Demand
If several fixtures are using hot water at the same time, the issue may involve system sizing, household demand, installation conditions, or a performance problem rather than a simple component failure.
Authorized Rinnai Dealer & Installer
Pathmaker Plumbing is an authorized Rinnai dealer and installer for homeowners considering a Rinnai tankless system or needing service on existing equipment.
A successful tankless installation depends on more than the brand on the wall. Household hot water demand, available utilities, venting or electrical requirements, water flow, and installation conditions all matter.
We evaluate the home and the expected demand before recommending equipment.
Tankless Water Heater Services
Tankless systems have different service and installation considerations than traditional storage-tank water heaters. We look at the equipment and the conditions around it before recommending the next step.
Tankless Water Heater Repair
When a tankless unit stops heating properly or becomes inconsistent, we diagnose the problem before assuming the equipment needs to be replaced.
Tankless Maintenance
Tankless systems may require periodic maintenance based on the equipment, water conditions, and manufacturer recommendations. Maintenance can help support reliable operation and gives us an opportunity to evaluate system condition.
Tankless Installation
New installations should be matched to household hot water demand, existing utilities, available space, and the work required to support the equipment.
Tankless Replacement
If an existing tankless unit has become unreliable or is no longer a good repair candidate, we can explain replacement options and what needs to be considered before selecting a new system.
Thinking About Converting From A Tank To Tankless?
A tankless conversion can be a strong upgrade, but it can also require more than simply removing the old tank and hanging a new unit on the wall.
The decision can depend on household hot water demand, gas capacity or other utility requirements, installation location, venting or electrical needs, and the amount of additional work required to support the system.
If tankless fits the home and the way you use hot water, we will explain why. If another tank-style system remains the better value, we will explain that too.
Is Tankless A Good Fit For Your Home?
The answer depends on the house and the household. We look at the conditions that actually affect installation and performance before recommending a system.

- On-demand water heating
- Reduced standby energy loss

Questions We Consider Before Conversion
