Tankless water heaters offer a number of advantages over traditional tanked models. They provide water on demand instead of storing it in a tank, which means that the hot water arrives instantly and never runs out. They cost less to operate than tanked models do, and they take up a great deal less space to boot. But like any other appliance, tankless water heaters run into trouble from time to time, and Bergen County, NJ residents should learn to look out for the telltale signs that something isn’t quite right. Here are 3 common problems with tankless water heaters that owners should look out for.


One of the principle selling points of a tankless system is that it provides hot water instantly. That creates a lot of hot exhaust that needs to be vented from the system or else it will cause an overload. If the venting is blocked or the heating mechanism is malfunctioning, you’re going to end up with an overload.


You don’t see nearly as much corrosion in tankless water heaters as you do in tanked models, since there’s no sitting water involved in a tankless system. However, condensation can be diverted onto components prone to corrosion, while a misaligned heat exchanger can do much the same. Simply replacing the corroded part won’t solve the problem. The technician needs to pinpoint the source of the corrosion and fix it.

3.     BUILD-UP

Hard water can cause problems to tankless water heaters over time: leaving a crusty white residue that interferes with its ability to do its job. Regular cleanings from a trained professional can keep the build-up to a minimum, but you may want to look into a water filtration system for your house to drop the hard water down.
