Tankless Water Heater Myths You Need to Stop Believing

3 / 7

They Don’t Supply Enough Hot Water

Another common myth regarding a tankless water heater is that once the water is used, water must be reheated, which can take up to 30 minutes. But there’s no storage tank, which means no shortage of hot water. The water is heated as it passes over a heating element to an outlet, so as long as you need the hot water, you’ll get it.

They Deliver Hot Water Instantly

A tankless water heater shouldn’t be purchased solely on the belief that it delivers hot water at the speed of light. Yes, it comes very quickly, but no, it’s not instantaneous. Essentially, the speed of hot water relies on the distance of the water heater from the faucet. Here’s how to replace a water heater thermocouple.

They Require Annual Inspections

Don’t believe the myth that you have to hand over cash each year for an inspection on your tankless water heater. There’s really no set time frame to service a tankless water heater, as it really depends on the hardness of the water. The harder the water, the quicker mineral deposits will build up in a water heater. Your tankless water heater will push most of this through the system, but if there is a buildup, the scale detection software will show you an error message, and then you’ll need to service it. Here’s what you need to know about DIY hot water heater repair.
