Facts About Common Tankless Water Heater Myths

If it's time for a new water heater installation, why not consider a tankless water heater? Before taking the plunge, make sure you know the facts about some of the common myths that surround tankless heaters so you can make an informed choice.

1. Myth: Tankless Water Heaters Never Break Down

Fact: Although a tankless heater is less prone to leaks and other issues that can plague tank heaters, they can have service issues. The most common problems concern hard water buildup and ignition issues. Fortunately, both are easily and inexpensively repairable, so they don't impact the lifespan of the water heater. You can avoid hard water problems and limescale buildup by having the water heater cleaned annually to remove the scale. Another option is to install a water softener on the inlet line into the water heater. As for ignition issues, an annual inspection should catch these early enough so that you can have them repaired.

2. Myth: Tankless Heaters Provide Unlimited Hot Water

Fact: One common myth is that one can never run out of hot water because the tankless heater heats water on demand. Although this is partially true, there can be too much demand placed upon a single heater. Depending on the capacity of your tankless heater, it may provide between two and five gallons of hot water a minute. This is plenty for a single shower, no matter how long it lasts, but you may run out of hot water if you are trying to heat two showers at once or running a washing machine and a faucet using the same heater. Most homeowners opt to install multiple tankless heaters if they plan to run hot water in two locations simultaneously. This way one heater isn't being overloaded.

3. Myth: Tankless Heaters Are Too Expensive

Fact: Although a tankless water heater cost more than a tank model initially, this extra expense very quickly evens out over the life of the unit. First and foremost, tankless water heaters are much more energy-efficient than a tank model. Further, many people use less water with tankless heaters because it doesn't take as long for warm water to reach the tap, to there is no need to leave the tap running for long periods as the water "heats" up. Tankless heaters also have a longer service life compared to tank heaters, so you won't need to replace it as often.
