Have you ever thought about the safety of your water heater? If not, it’s time to start. According to the US Fire Administration, an estimated 890 residential structure fires are caused by water heaters annually. That’s why it’s essential to make sure that yours is functioning properly and isn’t at risk of exploding. In this article, we will be exploring ‘Is Your Water Heater Safe or Is It About To Explode?’. So if you are having an expansion tank for water heater, tankless water heater or a gas heater, then this article is a must read for you.
Can A Water Heater Explode?
Yes, a water heater can explode for many reasons. Following are the major causes for your water heater to explode:
- The first thing to consider when evaluating whether your water heater is safe or not is its age. The majority of traditional tank-style water heaters last between 10 and 15 years before they need replacing. After this point, the build-up of pressure due to sediment can cause them to fail suddenly and even explode in some cases. So if your unit has been around for a while, it might be worth inspecting further.
- Another important factor is maintenance – regular inspections and flushes can help prevent corrosion from building up over time which would otherwise put unnecessary strain on the system allowing dangerous levels of pressure to accumulate.
Understanding how old your water heater is and making sure it gets proper maintenance are key things to consider when assessing its safety status. This article will provide more information on what signs indicate potential danger as well as practical advice on how best to proceed should any issues arise.
Why Does Water Heater Explode and Its Effects?
A water heater explosion occurs when the tank ruptures and releases stored hot water and steam generated due to heat energy within the system. It’s a sudden, violent event that can cause severe property damage as well as injury or death. The force of the blast is strong enough to break through walls and shatter windows.
The most common causes of water heaters exploding are due to corrosion, high pressure, faulty installation, poor maintenance, sediment buildup, malfunctioning of thermostats and gas leaks. These factors will be addressed in more detail in the following section.
Risk Factors For Water Heater Explosions
As with any household appliance, water heaters have their own set of risks. Understanding the risk factors associated with a water heater can help you determine if yours is safe or not.
| Risk Factor | Explanation |
| Age | Older models are more prone to failure and explosions due to wear and tear over time. |
| Poor Maintenance | Regular maintenance helps keep your water heater in good condition; neglecting it can lead to corrosion, rust, and other issues that increase the chance of an explosion. |
| Overheating | If the temperature control system is faulty, then the internal pressure could build up too high, leading to an explosion. |
It’s important to know what type of water heater you have as well, since different types may be susceptible to different hazards. For example, electric tankless water heaters don’t store hot water like regular tanks do so they’re at less risk for overheating-related explosions than traditional storage tanks. On the flip side, gas-powered tankless systems need extra safety features to protect against dangerously high temperatures caused by improper venting or air flow obstruction.
With this knowledge in hand, let’s explore different types of water heaters available today.
Different Types Of Water Heaters
There are several types of water heaters available.
