A tankless water heater takes a different approach: instead of keeping 40 or 50 gallons hot around the clock, it heats water only while a tap is open. When water starts moving, a flow sensor notices, a powerful burner or electric element fires, and the water is heated as it passes through a compact heat exchanger. The upside is significant: no standby heat loss, hot water that does not run out during back-to-back showers, a wall-mounted unit that frees up floor space, and a service life that often reaches twenty years with maintenance. For plenty of Apex, NC households, that makes tankless a smart upgrade.
The most important step happens before anything is installed. We total your peak demand in gallons per minute, such as a shower, a kitchen sink, and the dishwasher at once, and compare it against how much the unit must heat cold winter water. That tells us the real capacity you need. Next we check the supply side. Gas tankless units fire at up to around 199,000 BTU, so a half-inch line that fed an old tank is often too small. Condensing models vent through PVC or polypropylene and need a condensate drain, while non-condensing units need stainless steel venting. Electric units bring their own demands, often needing multiple large breakers and sometimes a service upgrade.
Every tankless install from Apex Water Heater includes isolation service valves so future descaling takes minutes instead of hours, proper gas piping with a drip leg, correctly pitched and terminated venting, and a pressure relief valve piped to a safe location. If your water is hard, we talk through scale protection, since mineral buildup is the main enemy of a tankless heat exchanger. We can add recirculation for faster hot water at distant bathrooms, set the temperature, handle permits where required, and walk you through maintenance before we leave.

Signs You Need Tankless Water Heater Installation in Apex
Most tanks announce trouble weeks or months ahead with rumbling noises, rusty water, or hot showers that keep getting shorter. Watch for these telltale signs that professional help is needed:
- Showers turning lukewarm before everyone gets a turn
- Construction or remodeling that opens walls and simplifies the install
- A tank water heater that is ten years old or more and due for replacement
- A utility area where a bulky tank takes up room you would rather use
- A far-off sink or bath where a point-of-use unit could help
- Preferring a heater that can be repaired and maintained instead of replaced every decade
- Standby losses on a tank that sits idle for long stretches
- Adding a bathroom, soaking tub, or larger shower that needs more hot water
Act Before It Gets Worse
A little rust-colored water or a relief valve that drips now and then can be the first hint of a tank that is close to the end. If you notice any of these signs, contact Apex Water Heater at (984) 273-8660 for a prompt inspection.

The Benefits of Professional Tankless Water Heater Installation
Buying the right unit is the easy part. The other half is making sure your home can support it. Gas tankless burners can fire at close to 199,000 BTU, so gas line sizing, meter capacity, and pressure under full load all have to check out. Vent materials, lengths, and terminations are dictated by the manufacturer and local code, and condensing units add a condensate drain that should be neutralized. Electric whole-home units can pull more current than an older panel can deliver. Miss one of these, and the unit underperforms or becomes unsafe.
Our technicians handle the full picture. We size the unit by flow rate and winter temperature rise instead of guessing, confirm gas pressure with the burner at maximum, and install venting and condensate lines exactly to specification. Every install gets isolation valves for easy descaling and a properly piped relief valve. We also give honest advice about whether tankless suits your home at all. For some households, a high-efficiency tank or a heat pump water heater makes more sense, and you will hear that from us before you spend money on a system that does not match how you live.
Step by Step: How a Visit Works
Our workflow is simple and thorough, so nothing gets missed between the fuel supply and the relief line. Here's what you can expect when you choose Apex Water Heater:
Flow Rate & Temperature Rise
Sizing starts with your peak demand in GPM and the temperature rise needed for cold winter water. That pairing tells us which unit will actually keep up.
Supply & Venting Plan
We confirm the gas line and meter can feed the burner's full BTU demand, plan the right venting, and check the panel for electric units before any price is set.
Careful Install
We mount the unit, run gas and venting to the manufacturer's specs, add isolation valves for descaling, and pipe the relief valve and condensate properly.
Test, Set, Explain
We fire the unit at full demand, check gas pressure under load, confirm the vent and condensate work, set the temperature, and show you how everything operates.

A few preventive steps can help you avoid a cold shower or a wet floor down the road. Here's where to begin:
- Flush the unit with a descaling solution annually to keep scale off the heat exchanger
- In freezing weather, keep the unit powered and insulate exposed piping
- Check and rinse the small filter screen at the cold inlet periodically
- Pay attention to error codes; they point to issues that are cheaper to fix early
- Consider a water softener or scale-prevention filter if your water is hard
- Check the vent cap outside for nests, debris, or buildup
- Set the temperature around 120F for safety and efficiency
DIY vs. Professional Tankless Water Heater Installation
The line between a safe DIY check and a risky repair is usually the moment you need to open a gas fitting, a vent connection, or an electrical cover. Here's a comparison:
| Factor | DIY Attempt | Hiring a Pro |
|---|---|---|
| Capacity | Sized by the box, not your demand | Matched to real peak demand |
| Gas Line | No check of meter or pressure | Gas pressure tested at high fire |
| Exhaust | Old flue reused or wrong vent material | Correct vent type, length, and termination |
| Power Needs | Wiring undersized for the load | Dedicated breakers sized correctly |
| Future Service | Service access ignored | Built for easy annual service |
| Outcome | Possible warranty and permit problems | Steady hot water at real demand |
