Tankless Water Heater Installation & Repair
Endless hot water, a smaller footprint and a longer life than a tank. TPM Services installs, repairs and descales tankless water heaters across the Las Vegas Valley, sized correctly for your home and installed to code.
Tankless Done Right for Las Vegas Homes
A tankless water heater heats water only when you open a tap, so you never run out in the middle of a shower and you’re not paying to keep 50 gallons hot all day. In Las Vegas that matters, because tank heaters in hot garages and hard water often fail in 8 to 10 years while a well-maintained tankless unit can last 20.
The catch is that tankless has to be installed correctly. Most units need a larger gas line than a tank, new stainless or PVC venting and the right size for how many fixtures run at once. We size the unit to your home, check your gas meter and line, and tell you honestly if tankless isn’t the best fit.

- You plan to stay in the homeThe longer life and lower energy use pay off over time.
- Your tankless unit shows an error codeScale, a clogged inlet filter or venting issues are common and usually repairable.

What Does a Tankless Water Heater Cost in Las Vegas?
Tankless installs vary more than tank replacements, so we price each one in writing after we look at your home. The biggest factors are:
- Unit size and brandFlow rate (gallons per minute) and whether you want a condensing or non-condensing model.
- Gas line capacityMany homes need a larger line from the meter to handle the unit’s gas demand.
- VentingNew venting through a wall or roof, depending on where the unit mounts.
- LocationReplacing a tank in the same spot is simpler than moving the heater.
- ExtrasIsolation valves for easy flushing, recirculation, and a water softener to protect the unit.

Frequently Asked Questions
How long does a tankless water heater last in Las Vegas?
With yearly descaling, a quality tankless unit commonly lasts about 20 years, roughly twice as long as a tank heater in a Las Vegas garage.
Do tankless water heaters work with Las Vegas hard water?
Yes, but they need to be descaled about once a year to remove mineral buildup. A water softener cuts down on scale and helps the unit last longer.
Will I need a bigger gas line for tankless?
Often, yes. Tankless units burn a lot of gas for short periods. We check your meter and existing line and upsize it if needed so the heater performs properly.
Do you install Navien tankless water heaters?
Yes. We install and service Navien and other major tankless brands, and we’ll recommend the model and size that fits your home.
Can you repair my tankless error code?
Yes. Most error codes point to scale buildup, a dirty inlet filter, ignition or venting problems. Call 702-932-5755 and we’ll diagnose it.
