We don’t think about our water heaters much—until there’s a cold shower involved. But there a surprising number of myths out there about water heaters that can lead to unnecessary repairs, higher bills, and even shorter lifespans for the system. At Donnie’s Plumbing in Temecula, we’ve heard every water heater myth in the book, and we’re here to set the record straight! Let’s dive into four common myths that many believe and the real truth behind them.
Myth #1: You Don’t Need to Flush Your Water Heater
Truth: Even if your water heater seems fine, flushing it regularly—usually once a year—is a smart move. Here’s why: as water heats up, minerals like calcium and magnesium settle at the bottom of the tank. Over time, this sediment builds up, making your water heater work overtime to keep the water hot. That means higher energy bills and, potentially, a system that wears out faster. Regular flushing keeps your heater efficient and helps it last longer. There are few exceptions as you can read about in this water heater blog. If you need help flushing your heater, just give us a call!
Myth #2: The Bigger the Water Heater, the Better
Truth: A bigger tank isn’t always better! Think about it—if your water heater is way too large for your home’s needs, you’re paying to keep water hot that you don’t even use. On the other hand, a tank that’s too small will run out quickly, leaving you with lukewarm showers when you need hot water most. The key is choosing a size that fits your household. If you’re not sure what size is best, we can help you find the perfect match.
Myth #3: Tankless Water Heaters Mean Instant Hot Water
Truth: Many folks think “tankless” means “instant hot water,” but that’s not quite right. Tankless water heaters heat water on demand, so you’re not using energy to keep water hot all day. But, just like with a regular tank, it still takes a moment for the hot water to reach your faucet or shower. So, while tankless heaters are energy-efficient and provide endless hot water, they don’t necessarily give you hot water the second you turn on the tap—especially if the unit is a ways away from where you need it.
Myth #4: You Should Crank Up the Temperature for the Best Results
Truth: Setting your water heater to the highest temperature won’t give you better results; it’ll just give you higher bills and a higher risk of scalding. For most homes, 120°F is the sweet spot. It provides plenty of hot water and keeps your energy costs down. Plus, at this temperature, you reduce the chance of mineral buildup and help prevent bacteria like Legionella from thriving.
Bonus Tip: Regular Maintenance Makes a Difference
Even with these myths debunked, it’s still a good idea to get a professional check-up once a year. Regular maintenance can spot minor issues before they become major problems and help keep your water heater running efficiently. A plumber can adjust your settings, flush the tank, and check for wear and leaks. So, a quick tune-up goes a long way toward ensuring your water heater is in top shape!
