Questions people ask us most.

Do tankless water heaters need to be flushed?

Yes. Even though a tankless unit has no storage tank, mineral scale still builds up inside the heat exchanger as water passes through it. Most manufacturers require an annual flush to keep the unit running efficiently and to keep your warranty valid.

How often should I flush a tankless water heater in Paradise, CA?

Once a year is the standard recommendation from most tankless manufacturers, and it's what we recommend for homes in Paradise, Magalia, and Chico. If it's been more than a year since your last flush, your unit is likely due.

How much does a tankless water heater flush cost?

Paradise Tankless Flush charges a flat $180 for a tankless water heater flush, supplies included, with no in-home quote required. Traditional tank water heater flush plus anode rod replacement is a flat $400, parts and labor included.

What happens if you don't flush a tankless water heater?

Mineral scale keeps building up inside the heat exchanger, which makes the unit work harder, reduces efficiency, can cause inconsistent hot water, and shortens the unit's lifespan. Skipping flushes can also void your manufacturer's warranty.

Does hard water make tankless water heater maintenance more important?

Yes. Homes with harder water tend to see mineral scale build up faster inside a tankless unit's heat exchanger, which makes annual flushing even more important. If you're unsure how hard your water is, flushing on a yearly schedule regardless is the safest approach.

Do I need a licensed plumber to flush a tankless water heater?

Not for a job this size. California's small-jobs exemption (Business & Professions Code §7048) allows unlicensed handyman work on jobs under the state's dollar threshold, with no employees and no building permit involved. Paradise Tankless Flush operates under this exemption and is not a licensed contractor, and carries general liability insurance.

We regularly service Rinnai, Navien, Noritz, and Rheem tankless units. Not sure about your brand or model? Send us a photo and we'll confirm before you book.
