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 from Holly Springs homeowners.
Gas service varies by subdivision here. Many newer neighborhoods have natural gas at the street, and some homes run on propane or are all-electric. Tankless units come in natural gas, propane, and electric versions, so we confirm your fuel before we pick the model.
A conversion is more than a swap. A tankless unit burns far more gas at once than a tank, so the gas line is often upsized. It also needs its own venting, a condensate drain on condensing models, power for the controls, and a wall to mount on.
Tankless is sized by flow rate, not tank gallons. We add up what your household runs at the same time, such as two showers, a dishwasher, and a laundry load, and choose a unit that heats that much water for your incoming temperature.
Many Holly Springs homes have a tank in the garage or a closet with no good way to vent a new unit. We can mount tankless on a garage wall or outside on an exterior wall, with the freeze protection, vent clearances, and gas connection the model calls for.
Navien and Rinnai units show codes for ignition, 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, scale, or a blocked vent.
If the tank in a 2000s or 2010s home is leaking at the base or cannot keep up, replacement is the moment to compare tank and tankless. We tell you plainly which one suits your household and your gas supply.
Clear Answers
We confirm natural gas, propane, or electric, check gas line size, plan the vent route and mounting spot, 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 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 requires it. We test flow and temperature at your fixtures and explain the annual descaling visit.
Tankless in Holly Springs
Most Holly Springs homes were built from the 2000s through the 2020s, in subdivisions like Sunset Ridge, 12 Oaks, Holly Glen, and Braxton Village. Many have a builder-grade tank in the garage or a utility closet, and those tanks are now reaching the age where they leak or run short. Households here tend to be big, so hot water demand is high, and that is exactly where a properly sized tankless unit helps.
Whether a home has natural gas depends on the subdivision. Where gas is at the street, a tankless conversion is mostly a matter of upsizing the line, venting, and mounting. Where it is not, we can install a propane unit or talk through an electric one, and we will tell you if the numbers favor a tank instead. Scale is what shortens tankless life, and Triangle water is moderately hard, so plan on a yearly descaling flush. If you would rather keep a tank, see water heater options. Financing is available.
Our shop is at 3460 Apex Pkwy in Apex, a short drive up NC-55, and we work Monday through Saturday, 7:00 to 18:00. Call or text (919) 679-1275, or book online. More about how we work in Holly Springs.
Commercial Tankless
Businesses that need 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 as a bank 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.
It varies by subdivision. Many newer ones have natural gas at the street, and some homes use propane or are electric. Look for a gas meter or a propane tank, or tell us your address and we will confirm during the visit.
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. Triangle water is moderately hard, so scale builds inside the heat exchanger. We flush the unit with a descaling solution, clean filters, and check venting and error history.
We install Navien and Rinnai tankless units and Bradford White tanks. We also repair and service most other tankless brands. If your unit shows an error code, call (919) 679-1275 and give us the code.
Yes. We replace tank heaters in Holly Springs homes and will tell you honestly whether a tank or tankless is the better fit. See our water heaters page for both.
