A tankless water heater heats water as you use it instead of keeping a full tank hot all day. For many households in Moore, OK, that means steady hot water and no bulky tank in the garage. It also means the system needs the right setup and regular care to work the way it should.
PlumbWorX LLC installs, repairs, and maintains tankless water heaters from our base at 101 Barbour St in Moore. Whether you’re thinking about switching or your current unit is acting up, we’ll give you a straight answer.

Tankless isn’t the best fit for every house, and we’d rather tell you that up front. Here’s how it compares with a traditional tank.
| Tank Water Heater | Tankless Water Heater | |
|---|---|---|
| How it works | Keeps a stored supply of water hot | Heats water on demand as it flows |
| Space | Needs room for a full tank | Compact, usually wall-mounted |
| Hot water supply | Can run out during heavy use | Steady flow when sized correctly |
| Upkeep | Periodic flushing and checks | Regular descaling and filter cleaning |
| Installation | Often a straight swap | May need gas, venting, or electrical changes |
If a tank turns out to be the better choice, our water heater installation in Moore page covers that route.
Switching from a tank to tankless takes more than swapping one box for another. We look at a few things before recommending a unit:
We install high-efficiency tankless units and review pricing with you before work begins, so you know what the upgrade involves.
Tankless units are reliable when they’re cared for, but they do have their own set of issues.
Mineral buildup, a dirty filter, or an undersized unit can cause temperature swings.
Most units display a code when something’s wrong. We find the cause instead of just clearing the code.
Gas supply, ignition, or venting issues can keep the burner from lighting.
Leaking fittings or unusual sounds are worth checking before they become bigger problems.
Minerals in the water slowly build up inside a tankless heater. Regular descaling and filter cleaning help it keep heating evenly, and in homes with hard water, that upkeep matters even more. Learn more about our water heater maintenance services or ask about water filtration.
Whether it’s a new install or a repair, the steps are simple.

Call or send a request and tell us what you have or what you want.

We check your setup, explain options, and review pricing with you.

We install or repair the unit you approve and test it before we go.
The $89 service call fee is waived when work is performed.
If your tankless unit has shut down completely or you smell gas near it, turn off its gas supply if it’s safe and call (405) 847-9809. You can also visit our emergency plumbing services page.

A tankless unit doesn’t run out the way a tank does, but it can only heat so much water at once. If too many showers and appliances run together, the water may cool. Sizing the unit for your household is the key, which is why we ask how your family uses hot water before recommending one.
From deciding whether to switch to keeping your current unit in shape, we’ll give you honest advice and careful work.
In most homes, yes. The switch may need changes to the gas line, venting, or electrical service. We check your setup first and explain what the upgrade would involve.
We work with natural gas and electric units. We don’t work on propane units at this time.
It depends on your water and how much hot water you use. Homes with harder water may need it more often. We can suggest a schedule after looking at your unit.
Error codes can point to ignition, venting, gas supply, overheating, or mineral buildup. We diagnose the cause so the problem doesn’t keep coming back.
