Are Tankless Water Heaters Safe?

Water heaters are common fixtures in most modern homes today. They ensure that no matter the outside temperature, hot water will always be available. And with advances in technology, there also comes improvements and new technologies added on to this fixture. A great example of this is the tankless water heater. However, this particular design has many homeowners wondering how safe it is. Let’s take a moment to discuss the benefits of the tankless water heater as well as its level of safety.


When it comes to comparing the difference between traditional and tankless heaters, they are as different as night and day. Take a look, below:

Remote Operation: if you are tired of manually maintaining your traditional heater, you will be glad to learn that tankless heaters are easier to operate. This is because most can be operated by remote control.

Smaller Size: most tend to take up less space than the more traditional models. This means if your home is small, you will not have to struggle with a bulky heater.

Energy Efficiency: one of the biggest benefits of tankless water heaters is that they do not work as hard as the traditional models. In fact, these heaters only need enough power to heat whatever amount of water is necessary at that given moment. The result? Say goodbye to wasted money.

Safety Features

Believe it or not, tankless water heaters can be safer than their traditional counterparts.There is no need for a tank which means that there is no storage unit and this lessens the chances of ruptures and leaks. Homeowners do not have to concern themselves with the problems that usually come with standing water – take sediment buildup in the tank for example. You can also avoid the odors that tend to come with the buildup of bacteria. However, there are a few things you should keep an eye on:

Temperature Setting: you need to make sure that your water heater is always set to a safe setting. The standard setting is typically around 120°F. Many of the tankless systems are computer-controlled which means their thermostats automatically remain on a safe setting.

Ventilation: make sure your heater is well-vented. This is to ensure that any harmful fumes are released. The good news is that most tankless systems have fan-operated venting which automatically expels exhaust each time the water has been shut off.

Monitoring: make sure to physically inspect your heater from time to time to make sure flow rates are optimal. The good news? Most tankless systems are self-monitoring.
