Tankless Water Heater Installation & Repair in Pahrump, NV
A tankless water heater heats water as you use it, instead of keeping a tank hot all day. ASC Plumbing installs, repairs, and maintains tankless water heaters for Pahrump homes and businesses.
Is a Tankless Water Heater Right for Your Property?
Tankless units save space and don't run out of hot water the way a tank can. But they have to be sized to how much hot water you use at the same time, and they need the right gas supply and venting, or enough electrical capacity. We look at all of that before recommending one.
When to Call About a Tankless Water Heater
- Your tank water heater is failing and you want to switch to tankless
- You keep running out of hot water
- You're adding a bathroom or need more hot water capacity
- Your tankless unit shows an error code or shuts off
- Water temperature swings, or goes cold in the middle of a shower
- Hot water flow has dropped over time
Tankless Water Heater Services
Tank-to-tankless conversion
We remove the old tank and plan the changes to gas, venting, water, and drain connections that a tankless unit needs.
Tankless repair
We troubleshoot error codes, ignition problems, temperature swings, and low flow.
Descaling and flushing
Hard water leaves scale in the heat exchanger. Periodic flushing keeps the unit efficient and helps prevent shutdowns.
How Tankless Water Heater Service Works
1. Review your hot water use
How many fixtures run at once, and what you need the unit to keep up with.
2. Check gas, venting, and power
We confirm the supply and venting a tankless unit needs, or plan the changes.
3. Install or repair
We complete the approved installation or repair.
4. Test and explain
We test temperature and flow and explain the maintenance schedule.
Hard Water and Tankless Heaters
Pahrump's hard water is tough on tankless units. Scale builds up in the heat exchanger and can cause error codes, reduced flow, and early failure. Regular descaling helps, and a water softener reduces how quickly scale builds up.
Gas Supply and Venting
Gas tankless units often need more gas than a tank water heater, and they have their own venting requirements. Your existing gas line may need changes. ASC Plumbing also provides gas line services, so that work can be planned together.
Tank or Tankless?
A tank costs less up front and is simpler to replace. Tankless saves space and gives continuous hot water within its capacity, but costs more to install. Compare them side by side in tank vs. tankless water heaters.

Frequently Asked Questions
Which tankless water heater brands do you service?
All brands, including Navien, Rinnai, Noritz, Rheem, and Takagi, in both gas and electric models.
How often should a tankless water heater be flushed in Pahrump?
With Pahrump's hard water, many tankless units need descaling about once a year. Follow the manufacturer's schedule, and flush more often if the unit shows scale-related error codes.
Can my gas line support a tankless water heater?
Not always. Gas tankless units often need more gas than a tank heater. We check the gas line size and supply before installation and plan any changes.
Why does my tankless water heater go cold in the middle of a shower?
Common causes are too many fixtures running at once, scale in the heat exchanger, a dirty inlet filter, or an ignition or gas supply problem. We can find the cause.
Is a tankless water heater worth it?
It depends on your hot water use, your current setup, and how long you plan to stay. Tankless saves space and provides continuous hot water, but costs more to install than a tank.
Do you repair tankless water heaters?
Yes. ASC Plumbing troubleshoots and repairs tankless water heaters, including error codes, ignition problems, and low flow.
