Dangers of tankless water heaters & Their Solutions

In this guide, we are going to Identify the Dangers of tankless water heaters and provide you with the potential safety measures to avoid any explosions, leakages, hazardous gas emissions, etc.

So without wasting your time let’s dive in;

Dangers of tankless water heaters

The following could be the potential hazards of the tankless water heaters.

Dose Tankless System Emit Dangerous Gases?

The tankless water heaters can emit carbon monoxide, carbon dioxide, nitrogen oxide, and hydrogen sulfide.

These gases are hazardous to your health in enclosed areas. The units should be installed in a well-ventilated area. Otherwise, you can create a passage to emit out the hazardous gases from the ventilations if your unite is installed in a closed basement.

What Causes A Tankless Water Heater To Explode?

Gas leakage is the most common cause of the explosion of gas tankless water heaters. If there is leakage of gas it can cause fire or explosion due to the presence of ignition sources (i.e. pilot light, uncovered power circuits, etc.).

This can be overcome by keeping a proper check on your tankless water heater thus, reducing the risk of explosion in the future.

How To Reduce Chance Of Tankless Water Heater Explosions:

Do not install the tankless water heaters near garbage cans, stoves, furnaces, etc. which produces combustion particles that can trigger off an explosion when present in high amounts.

Gas leakages:

Gas leakages can lead to a significant impact on your health and may even prove fatal for you. It should be checked regularly that there are no leakage problems or not. Most people forget to do it and it becomes a significant reason for explosions in tankless water heater units.

How To Reduce or Detect The Gas Leakages

You can detect gas leakage by applying soapy water solution over the joints of your unit. If you notice bubbles, it means there are some leaks in them and should be repaired or replaced to avoid any hazardous situation.

You can also install carbon and other gas detectors to detect such types of hazardous gases.

Are Tankless Water Heaters Safe?

Tankless water heaters are the latest models of heating appliances. These are generally preferred over traditional tank-type systems as they have various advantages. However, there are heated debates ongoing whether these appliances are safe to use or not.

The main concern is that Some of the modes utilize natural gas, which can be extremely dangerous if there is even a minor leakage.

It has been reported that in the last few years, there have been dozens of cases where people lost their lives due to carbon monoxide poisoning because of leakages from these tankless water heater installations.

Some studies also state that it might cause an explosion if proper ventilation is not provided while installation and usage of these appliances.

How To Minimize The Danger?

If you consider having a tankless system, then keep the following points in your mind to minimize its dangerous effect.

Install Your Unit Properly:

You should always keep safety first. An installed water heater is usually safe, but it can be dangerous if you do not follow the proper guidelines for installation like venting it properly.

If there are any cracks in your unite, then replace them as soon as possible because these gaps can cause leakage of gas which results in fire or even an explosion.

If your tankless water heater has a warranty option, then you could check their regulations before replacement.

Install Carbon Monoxide Detectors In Your Home:

To detect carbon monoxide or other gases present near your unit, install a carbon monoxide detector near the unit.

It will alert you by emitting a beep whenever there is an excess amount of poisonous gases so that you can take necessary actions immediately to avoid any harmful effects.

Keep Maintain Your Unite:

You should take regular check-ups for your tankless water heating system and make sure that it is up and running fine to avoid any hazard.

If you hear any strange sound coming from your unit either due to gas leakage or some other problems, then don’t ignore it and repair the same without wasting time.

If you keep these points in your mind, then you can minimize the chances of explosions, fire, or carbon monoxide poisoning caused by the tankless water heaters.

Seek Help From Expert Plumber If Your New:

If you are not sure how to install a tankless water heater safely, then take help from a professional plumber to make sure that it is properly installed.

This will also help you in minimizing the chances of any risk and even prevent accidents and disasters.

Tankless vs. Tank Water Heater Dangers:

Both of them are beneficial in their way, but if you consider the safety perspective then tankless water heaters are more advantageous over the traditional system.

This is because the main danger with a tank unit is that it can explode or burst even due to small reasons like overheating or anything else.

Plus, there is also the chance of leakage involved with these systems if not maintained properly. But, this problem relatively less exists with the tankless water heaters as they will shut down immediately when something goes wrong. This feature makes it more reliable and safe for use than any other type of water heater system available in the market today.

Here is the detailed comparison of the tank and tankless water heater


Thus, after discussing all the points and facts related to the dangers of tankless water heaters, we can conclude that tankless water heaters are much safe and reliable than the traditional system.

These systems offer various advantages like longer durability, better performance, and energy-saving capacity that make them very popular among several consumers today.
