If you are tired of running out of hot water, a tankless system might be a great fit, and we are happy to talk it through with you. Tankless units skip the standby heat loss and give you endless hot water on demand. We install gas and electric tankless units from A.O. Smith, Rinnai, Navien, Takagi, Noritz, and others, and handle tank-to-tankless conversions for homes ready to upgrade.
Best fit for tankless: bigger families who run out of hot water; homes wanting reduced energy bills; long-term homeowners (the long lifespan rewards staying put). Anybody who wants endless hot water may want one.
| Feature | Gas Tankless | Electric Tankless |
|---|---|---|
| Flow rate (GPM) | Typically 5-11 GPM | Typically 2-8 GPM |
| Whole-house capable | Yes: handles multiple fixtures simultaneously | Sometimes, for smaller homes; whole-house units draw a lot of power |
| Energy efficiency | About 0.81-0.97 UEF (condensing models at the top) | About 0.98-0.99 UEF |
| Installation | Often needs a larger gas line and new venting (PVC for condensing units) | Whole-house units can draw 100+ amps; often need a panel or service upgrade |
| Operating cost | Generally lower (gas usually cheaper) | Depends on local electric rates |
| Upfront cost | Higher install if gas line needs work | Higher install if panel upgrade needed |
| Best for | Whole-house replacement, high hot-water demand | Point-of-use, additions, no gas hookup, smaller homes |
| Lifespan | 15 to 20 years with regular descaling | 15 to 20 years with regular descaling |
Things to plan for: very high simultaneous demand (multiple showers + laundry + dishwasher at once) may need two tankless units in parallel, which we size for you; homes with limited gas line capacity (may need gas line upsizing, adding cost); short-term rentals/flips (won't recoup the upfront cost).
We give you a real-world recommendation based on your specific household, not a sales pitch.
We repair tankless water heaters, including the A.O. Smith, Rinnai, Navien, Takagi and Noritz units we install. Most problems show up one of three ways:
Descaling: Inland Empire water is hard, and scale builds up inside the heat exchanger. Descaling flushes it out with a descaling solution through the unit’s service valves, which keeps the heater running efficiently and protects it. We recommend it once a year in our hard water, and we clean the inlet filter while we are there.
You get your options in writing, each with one flat-rate price, before any work begins.
A tankless heater stores almost no hot water, so it creates very little thermal expansion. If you’re switching from a tank to tankless, the expansion tank you have now may not be needed anymore, and we’ll tell you so honestly instead of selling you a new one.
If your home keeps a storage tank anywhere in the system, such as a buffer tank or a second water heater, the expansion tank still matters. Its air charge has to match your home’s water pressure to work. Expansion tanks are pre-charged at the factory (commonly 40 PSI, depending on the brand), while many Inland Empire homes run 60 to 80 PSI.
When an expansion tank is part of the job, we measure your home’s water pressure and set the air charge to match before it goes in. Most plumbers skip that step. We never do.

The company was responsive and professional. Jerry, their representative showed up on time, gave us a detailed quote and installation. I would recommend this company and this tech to others needing a water heater installed.
Freddy the serviceman was great. He explained everything in detail about what needed to be done. He replaced my water heater and a few other things that needed attention. Very pleased with the work he completed. Will use Sweetwater plumbing again when needed…
