Tankless Water Heaters
Tankless water heaters give you hot water without a tank to run out, and they commonly last 20 years or more with care. We install, service, and repair them across Cary from our shop in Apex. We tell you honestly whether your home is a good fit, and you get the real price before we start.

Tankless Installation, Service and Repair
Whether you are planning a switch or have a unit that is acting up, these are the six we hear most.
Three things decide it: gas service (or the electrical capacity for an electric unit), how much hot water you use at once, and a wall with room for the unit and its vent. If one is missing we say so, and sometimes a good tank is the better answer.
A conversion is more than a swap. Tankless units burn more gas at once, so the gas line is often upsized. They need their own venting, a condensate drain on condensing models, an electrical outlet, and a wall mount location.
Tankless is sized by flow rate in gallons per minute and by how many fixtures run at once. We add up your simultaneous use and pick a unit that covers it, rather than guessing by square footage.
Navien and Rinnai units display codes for ignition failure, flame, flow, vent, and temperature faults. We read the code, test the part behind it, and repair it. Common causes are a dirty flame rod, a stuck flow sensor, or a blocked vent.
Cary water is moderately hard. Scale coats the heat exchanger and flow sensor, and the unit loses efficiency or throws errors. A descaling flush clears it, and doing it yearly is the single best thing for a tankless unit.
Where indoor wall space is short, we can mount a unit outside on an exterior wall, with the freeze protection, vent clearances, and gas connection the model calls for.
Clear Answers
We check gas supply and line size, venting route, and mounting wall, and count your peak flow. You get the real price in writing before we start, and nothing begins until you approve it.
We remove the tank, mount a Navien or Rinnai unit, and run the gas line upgrade, venting, condensate drain, and electrical connection it needs. Isolation valves go on so the unit can be flushed later.
The work is permitted and inspected where the Town of Cary requires it. We test flow and temperature at your fixtures and explain the yearly descaling visit.
Tankless in Cary
Cary homes built in the 1990s and 2000s usually have a gas line sized for a tank heater, a furnace, and a range. Adding a tankless unit can push that line past what it carries, so we check it first and upsize where needed. Many homes in Preston, Lochmere, and Cary Park have attic or garage heaters, and a tankless unit may move to an exterior wall or garage wall with new venting.
Cary water is moderately hard, and scale is what shortens tankless life. Plan on an annual descaling flush, and consider a water softener. We also install and service softeners in town, see water softener installation and repair in Cary. If you are not sure about the switch, compare it with a tank replacement in Cary. Financing is available.

Commercial Tankless
Businesses that need a lot of hot water on demand are a natural fit for tankless. We install and service commercial tankless systems as well as home units.
Several Navien or Rinnai units piped to work together cover restaurant and salon demand, and if one needs service the others keep running.
A recirculation loop keeps hot water near the fixture, so sinks and shampoo stations deliver quickly and less water goes down the drain.
Several units draw a lot of gas at once. We check the supply, upsize the line where needed, and handle venting and permits.
Helpful Details
Tankless generally runs $4,000 to $6,000 installed, compared with $2,000 to $4,000 for a standard tank. The exact number for your home comes in writing before any work starts. Gas line size, venting, and unit location drive the difference.
Often, yes. A tankless unit burns much more gas at once than a tank. We check the existing line and the total load before we quote and upsize where needed.
Once a year in Cary, because the water is moderately hard. We flush the unit with a descaling solution, clean filters, and check venting and error history. A softener reduces the scale.
Navien and Rinnai. We also repair and service most other tankless brands.
Note the code and call us at (919) 679-1275. Many codes point to scale, a flame sensor, flow, or a blocked vent, and we can usually tell you the likely cause on the phone before we visit.
It heats as water flows, so it does not run out like a tank. It does have a flow limit. If too many fixtures run at once, the temperature drops, which is why sizing matters.
