Tankless water heaters have been available in the U.S. since the 1990s, yet misinformation about the appliances persists. Most people understand that a tankless water heater is more efficient than a conventional tank heater. Beyond that, confusion abounds.
Let’s set the record straight. Here’s what you need to know about tankless water heaters.
3 Common Misconceptions About Tankless Water Heaters
They deliver hot water instantly: When the tankless water heater was introduced in the U.S., some of the marketing around, it was at least a little misleading. Even today, you’ll hear some people refer to it as an “instantaneous” water heater.
It’s true that a tankless water heater will heat water the instant it’s needed. That’s what makes it so efficient. Unlike a tank water heater, an on-demand water heater doesn’t keep hot water on standby. But don’t confuse “instantaneous” with immediate delivery of hot water at the tap. You’ll still have to wait for the water to warm up before stepping foot in the shower.
They don’t require maintenance: They certainly do! Most manufacturers recommend annual maintenance to prevent limescale and calcium from developing on the components. This buildup can hinder the appliance’s performance and shorten its lifespan. That’s why you have to descale the tankless water heater periodically. Be sure to follow the instructions in the owner’s manual.
Scale buildup is a common problem in homes with hard water. Installing a water softener will also help protect your tankless water heater, as well as your plumbing and all water-using appliances.
They don’t last as long as a tank water heater: Surely, something as advanced as a tankless water heater, with all those sensitive components, won’t last as long, right? Wrong! Because the tankless water heater only operates when needed -- unlike the tank kind, which is continually running -- it will last upwards of 20 years with routine maintenance. A tank water heater’s life expectancy is only 10 to 15 years.
