Tankless Systems Have Been on the Rise Since 2014
In California, tankless water heaters have become more common over the past decade. A big reason is Title 24 energy efficiency standards, which were updated in 2014 and encouraged builders and homeowners to move away from older, less efficient tank-style units. At the same time, rebates from utilities and growing consumer awareness about saving energy and water made tankless systems a natural choice.
Today, it’s not unusual for buyers to expect a tankless water heater in their new home or for sellers to highlight one as a selling feature. But here’s what many homeowners don’t know: while tankless systems are efficient, they require regular flushing to perform the way they should.
Why Flushing Tankless Systems Matters
- Hard water makes California a tough environment
Most regions in California have hard water. That means mineral buildup (scaling) happens fast. Inside a tankless system, scaling coats the heat exchanger and narrows water flow, which can lead to weak hot water pressure, system errors, or complete breakdowns if ignored. - Efficiency depends on it
Tankless systems are designed to cut energy costs, but sediment buildup forces the system to work harder. A neglected system loses efficiency and cancels out the very reason most people chose tankless in the first place. - It protects compliance and resale
Since 2014, California inspectors and appraisers have been looking at energy efficiency more closely during transactions. A well-maintained tankless system reassures buyers, while a neglected one can show up on an inspection report and become a sticking point in negotiations. - Maintenance saves thousands
Replacing a tankless water heater can cost $3,000–$5,000. A professional flush normally costs from $150–$350 depending on the service provider. Regular flushing keeps the system working properly for years, which protects both the homeowner’s wallet and long-term property value.
What Realtors Should Tell Their Clients
- Annual flushing is standard. Once per year is the minimum. Homes with extremely hard water or older tankless units may need flushing every six months. Homes with a water softener can usually extend the time in between flushes.
- Tankless does not mean maintenance-free. Many buyers assume “tankless” means “set it and forget it.” They need to know that’s not the case.
- Service records matter. Just like HVAC tune-ups, showing proof of regular flushing can help sellers during disclosures and give buyers peace of mind.
How Realtors Can Stand Out
- Include “Annual Tankless Flush” on your buyer handouts or new homeowner checklists.
- During listing prep or walkthroughs, ask the seller when the last flush was done. If they don’t know, recommend it before inspection.
- Build trust by pointing clients to a professional service company. That small referral cements your role as a problem-solver, not just a transaction closer.
The Bottom Line
Tankless water heaters have been part of California homes for more than a decade, thanks to 2014 efficiency standards and rebates that made them attractive upgrades. They’re smart investments, but only if they’re maintained. A simple flush once a year protects efficiency, extends the system’s life, and keeps inspectors — and buyers — happy.
