Can Water Heaters Explode? The Best Safety Tips

Did you know that the average household is spending just over $3,000 each year on home maintenance issues? If you’re trying to avoid significant expenses, you’ll want to prioritize staying on top of the major parts of your plumbing and HVAC systems. That effort includes monitoring units like your water heater to ensure they are operating safely.

Can water heaters explode? Yes, they can if you’re not careful. Read on to find out what you should look for and how to stay safe!

Know the Causes of Water Heater Dangers

One of the biggest water heater dangers is the sheer intensity of the temperatures in the unit. Most units can get up to 140 degrees, though recommended temperatures are closer to 120 degrees. If that scalding hot water bursts out, you’ll end up in a dangerous situation.

Water heaters use pressure relief valves to help gauge internal pressure within the unit. If this valve fails or wears down over time, however, that can lead to catastrophic failure and, potentially, an explosion.

Yes, water heaters are supposed to maintain a high internal temperature so you can enjoy hot showers. But that temperature can get too high. You may notice the pressure valve going into overdrive to attempt to regulate the flow of water in the tank and release pressure.

But if that valve or any other part malfunctions, you’ll have a problem. Sometimes water heaters can fail and produce cold water, but the scarier possibility is water that is too hot. That’s why regular maintenance is crucial to detect problems with parts.

Another issue that could increase the risk of an explosion is if your water tank’s body is rusted. If it is, excess amounts of sediment in the tank may obstruct the flow of water. The sediment also has an insulating impact, which drives up the temperature even more.

This, in turn, can cause pressure to build, leading to an explosion. If a tank explodes, steam and hot water will be released into your home. There’s potential for life-threatening injuries as well as structural damage to your home.

Keep Your Senses Alert to Problems

To help prevent a water heater explosion, you’ll need to be alert to changes. Some of the signs that something is wrong are visual, while others can be heard. And in some cases, you’ll need to rely on a trained technician to spot the problems.

For instance, do you hear an unusual popping noise coming from your water heater? That popping noise could mean your tank contains too much sediment, and the water trapped beneath it is boiling. As a result, that trapped water could trigger too much heat and pressure and lead to a dangerous situation.

You also might hear a whistling or gurgling sound. This, too, can indicate that water might be trapped beneath sediment in the tank. If there is any question as to what sound your water heater is making, take action.

Is your water looking brown? That’s another clear indicator that it’s time to clean your water heater tank. Brown water indicates that the tank has too much sediment or rusty parts are leaking into your water supply.

Finally, pay attention to smells. If you smell something that seems like a rotten egg, you could be dealing with a gas leak connected to your water heater. Regardless of the source, you never want to mess around with a gas leak.

Left unattended, a leak could result in an explosion. Water heaters use a pilot light, and that source of ignition could lead to significant water heater dangers.

Practice Regular Maintenance

Ultimately, your best strategy to avoid a water heater explosion is to invest in regular maintenance. Skilled plumbers can offer inspections and routine maintenance. Or you might need to pursue hot water heater replacement.

When it comes to water heater safety tips, make sure to complete a yearly assessment of your water heater. Tank flushing, air intake filter replacement, and temperature checks are all essential forms of maintenance. A temperature that is above the optimal range of 120 to 125 degrees could pose a greater risk.

While a certified plumber should do the annual maintenance, there are some tasks you can complete. Stay alert to unusual noises and smells. And check the pressure relief valve on a monthly basis, too.

Simply lift the lever to ensure that water comes out. If that does happen, your valve is working effectively to mitigate pressure issues. If that doesn’t happen, you’ll want to call a plumber to do an inspection and replace the part.

If you need a new water heater, investigate different types of water heaters. While more expensive, tankless water heaters have the advantage of taking up a smaller footprint. And because they don’t use a tank to store extremely hot water, they are safer.

You won’t have to worry about a home water heater explosion with a tankless option. Additionally, these water heaters won’t promote the growth of bacteria because they lack a tank. And they will last longer because they won’t be subject to corrosion and rust.

Can Water Heaters Explode?

Are you still wondering, “Can water heaters explode?” Yes, they can if you avoid routine maintenance and fail to notice signs of problems. Your best bet is to hire a professional technician to check your water heater annually and pursue repairs or replacement as needed.
