Thinking about replacing your water heater in Cary, NC? Don’t sweat it—unless, of course, your hot water just went out. In that case, read this now and thank us later.
Whether you’re a homeowner, new to the area, or just DIY-curious, this guide walks you through what type of water heater to choose, how to stay on the right side of Cary’s building codes, and how not to blow a gasket (literally or figuratively).
Why a New Water Heater?
- Your showers are turning into polar plunges.
- You hear rumbling noises like a T-Rex moved into your garage.
- It’s over 10 years old and clinging to life.
In short: it’s time.
Types of Water Heaters (and Which One Cary Folks Prefer)
| Type | Fuel | Pros | Cons | Cost (Installed) |
|---|---|---|---|---|
| Tank (Traditional) | Electric/Gas | Lower upfront cost, easy to install | Less efficient, runs out of hot water | $1,200–$2,000 |
| Tankless | Gas/Electric | Endless hot water, energy-efficient | Higher cost, may require upgrades | $2,000–$3,500 |
| Heat Pump | Electric | Super efficient, eco-friendly | Needs space, slow recovery | $2,500–$4,500 |
Quick Tip: Most Cary homeowners still opt for tank heaters due to lower costs and simplicity. But if you’re techy and want long-term savings, tankless or heat pump units are worth exploring.
Permit? Yes, Please (And Thank You, Town of Cary)

- Permit fee: ~$80-$100
- Expect an inspection after installation
| Step | Description |
| 1. | Submit permit application online |
| 2. | Get approval and schedule inspection |
| 3. | Complete installation (DIY or contractor) |
| 4. | Town inspector checks for code compliance |
Fun Fact Box: Did you know Cary is one of the few Triangle-area towns that allows homeowners to pull their own permits (if you’re living in the home)? DIYers, rejoice!
Top 5 Mistakes to Avoid (Seriously)
| Mistake | Why It Matters |
| Skipping the permit | Violates code; fails home inspection later |
| Choosing wrong size | Too small? Cold showers. Too big? Energy waste |
| Bad placement | Can violate clearance rules |
| Forgetting expansion tank | Required if you have a closed system |
| Not hiring licensed pro | Risk of leaks, gas issues, insurance denial |

| 3–4 people | 40–50 gallons |
| 5+ people | 50–80 gallons |

FAQ:
What’s the real cost to install a water heater in Cary?
Many homeowners get quoted between $1,000 and $2,000 for a 50-gallon tank, which includes labor, permits, and hauling away the old unit. As one plumber explained on r/homeowners:
“If they aren’t charging at least $250 an hour they are either unlicensed… or teetering on the edge of bankruptcy.”
Bottom line: licensed pros factor in parts, permits, liability insurance, and code compliance—so go cheap at your own risk.
Can I buy a water heater from Home Depot or Lowe’s and do it myself?
Yes—but plumbers caution it’s not always worth the hassle. A homeowner said it took 5 hours and three trips to Home Depot. The real danger isn’t just time—it’s potential failure to meet code, risk of leaks, and permit troubles.
Is tankless worth it for Cary homes?
Yes, especially if you’re looking for energy efficiency and space-saving. Cary’s mild winters are favorable for tankless systems since they don’t have to work overtime like in colder regions.
How do I know if I need a new water heater or just a repair?
You might only need a repair if the unit has:
- Minor leaks from fittings
- Heating element failure (electric heaters)
- Sediment buildup
You likely need a replacement if:
- The tank is rusting
- There’s a major leak
- It’s over 10–12 years old and inefficient
What’s the difference between Lowes/Home Depot installs vs. local Cary plumbers?
Big-box stores often subcontract the job, which could mean less personal service or higher turnaround time. Local plumbers in Cary typically offer faster response, local code expertise, and better accountability.
How long does it take to install a water heater?
A standard installation typically takes 2–4 hours. That may vary if you’re switching fuel types (e.g., from electric to gas), upgrading tank size, or needing code-related adjustments.
Can I reuse the existing vent or gas line for a new water heater?
Sometimes. However, upgrades may be needed to meet current codes. Always have your installer inspect the existing setup.
