Why do so many people switch to tankless? Mostly three things: hot water that keeps coming, lower standby energy use, and space. A tankless heater stays idle until you open a tap, then fires a high-output burner or electric element and heats the water in passing. With no stored water to keep warm, it wastes less energy between uses, and with regular descaling it can last twenty years or more. It is not magic, though. Performance depends entirely on sizing and installation, which is where our attention goes on every Norman, OK install.
Sizing is where tankless installs succeed or fail. We work from two numbers, flow rate and temperature rise: add up the fixtures you realistically run at the same time in gallons per minute, then factor in how cold the incoming water gets in winter, since a unit that delivers five gallons per minute at a mild rise may deliver far less when the groundwater is cold. Then comes the infrastructure. A whole-home gas unit can draw several times the gas of a standard tank, which often means a larger gas line or confirming the meter can keep up. Venting must match the unit, and electric tankless models can need a large share of your electrical service, sometimes enough to require a panel upgrade.
Every tankless install from Norman Water Heater includes isolation service valves so future descaling takes minutes instead of hours, a clean gas connection with a sediment trap, 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.

Warning Signs to Watch For
Water heaters usually give plenty of warning before they fail, as long as you know what to look and listen for. Here are the most common indicators that it's time to call a professional:
- More people or more fixtures than your current heater was sized for
- Wanting a unit that can last up to twice as long as a typical tank
- Standby losses on a tank that sits idle for long stretches
- A remodel that would benefit from a compact wall-mounted heater
- Construction or remodeling that opens walls and simplifies the install
- An addition or guest suite that is a long run from the main heater
- Hot water running out during back-to-back showers
- A water heater near the end of its service life, making this a natural time to switch
A Slow Leak Never Stays Slow
Most water heater failures start small: a popping sound from sediment, a damp spot under the drain valve, or a shower that goes lukewarm a few minutes sooner each week. If you notice any of these signs, contact Norman Water Heater at (405) 785-5893 for a prompt inspection.

Why This Job Calls for a Pro
Tankless installation is more involved than swapping a tank. A whole-home gas unit can demand several times the gas flow of a standard tank, and running it on an undersized line causes ignition faults and inconsistent temperatures. Venting is equally specific: condensing units use plastic vent pipe and need a condensate drain, non-condensing units need stainless steel, and neither can simply reuse the old tank's flue in most cases. Electric tankless can require multiple large circuits, and mistakes with gas, venting, or high-amperage wiring carry real fire and carbon monoxide risks.
A professional install protects both performance and safety. We start with a real demand assessment, check the gas line, meter, and panel, and design venting that meets the manufacturer's requirements. The install includes service valves, a sediment trap, a correctly routed relief valve line, and a neutralized condensate drain where needed, followed by a full-flow test. Just as important, we tell you plainly if a tank, hybrid, or smaller point-of-use unit would serve you better. The right fit matters more to us than the type of unit.
How We Handle Tankless Water Heater Installation
We work through a clear, repeatable process so you always know what's happening and what it will cost. Here's exactly how a typical visit unfolds:
Flow Rate & Temperature Rise
Sizing starts with your peak demand in GPM and the temperature rise needed for cold incoming water. That pairing tells us which unit will actually keep up.
Gas, Venting & Power Check
Gas line size, meter capacity, vent routing, condensate drainage, and electrical service all get checked, so the quote reflects the real job.
Careful Install
Every connection follows the manual and local code: gas, venting, relief valve discharge, condensate, and isolation valves for future maintenance, with permits handled where required.
Startup & Verification
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.

Tap to Call (405) 785-5893How to Prevent Water Heater Problems
Routine maintenance is almost always cheaper and easier than an early replacement. Start with these practical measures our team relies on:
- Check the vent cap outside for nests, debris, or buildup
- In freezing weather, keep the unit powered and insulate exposed piping
- A setting near 120F limits scalding and reduces scale formation
- Treating hard water protects the heat exchanger from mineral buildup
- Plan on yearly descaling through the service valves, sooner if your water is hard
- If the unit shows a recurring code, note it and have it checked
- Check and rinse the small filter screen at the cold inlet periodically
DIY vs. Professional Tankless Water Heater Installation
Relighting a pilot by following the label is one thing. Diagnosing a gas valve, a burned-out element, a dirty flame sensor, or a tankless error code calls for meters and know-how that a pro brings. A side-by-side look:
| Consideration | Doing It Yourself | Hiring a Pro |
|---|---|---|
| Capacity | Guessed from the old tank size | Calculated for your coldest months |
| Gas Line | No check of meter or pressure | Line and meter verified for full BTU demand |
| Exhaust | Old flue reused or wrong vent material | Venting built to the manufacturer's specs |
| Power Needs | Overloaded circuits and tripped breakers | Service upgrades flagged up front |
| Future Service | Service access ignored | Isolation valves installed for quick descaling |
| Outcome | Possible warranty and permit problems | Safe, inspected, and working as designed |
