Tankless Water Heaters
If you’re not aware of what a tankless hot water system can do for you, then you need to speak with the highly trained, tankless water heater experts at Justice Plumbing, the only certified Rinnai Pro‘s in Hood County.
With a tankless water heater, your home’s cold water is heated only when you need it, and it stays hot until you’re done using it. This results in a limitless hot water supply and little to no wasted energy usage. No more worrying about having no hot water for your bath, shower, clothes or dishwashing machines. A tankless hot water system heats the water on demand, right when you need it.
Life is Better With Tankless
Your family can enjoy hot water from anywhere in your home. Two showers running at once? Laundry and dishes at the same time? Not a problem. Experience a limitless supply of uninterrupted hot water. Rinnai tankless water heaters use up to 40% less energy than a traditional tank – and last twice as long!

YOUR ESSENTIAL APPLIANCE
The Heart of Your Home
Think of plumbing as your home’s vital arteries, supplying critical fluid—in this case, hot water—to critical areas at critical times. At the center of this system is your hot water heater. If it fails to perform as needed, everything it supports—showering, bathing, washing dishes and clothes—will fail too.

There are two types of periodic maintenance that your service technician should perform to keep your tankless water heater in top shape. It’s important to note, the time in between necessary maintenance will depend on the water quality in your home.
- The in-line screen filter should be checked periodically for debris and cleaned.
- The unit should be flushed annually to keep it free of scale and lime, which can shorten the water heater’s lifespan over time.
