Having a tanked water heater in your home means you can easily take hot showers, wash dishes, and do many other daily activities that involve hot water. Unfortunately, these appliances can suffer extensive damage without proper maintenance. In worst-case scenarios, a tank explosion could occur.
What causes water heaters to explode? Our experts at Hats Off Heating and Air Conditioning provide plumbing services in Norfolk, VA, including water heater services, so we know the problems these appliances could develop. Review our guide to learn how and why these appliances explode and keep your household safe from a dangerous explosion.
Top Water Heater Explosion Causes
What causes water heaters to explode in Norfolk? Here are the main reasons:
Gas Leaks
Gas leaks are usually the culprit behind blown gas-fueled equipment. Natural gas is flammable, so if a leak exposes the fuel to a heat source, like the heater’s pilot light, the appliance could explode.
Excessive Tank Pressure
High pressure levels inside the tank are another problem for gas and electric systems. Heating water naturally generates pressure, but tanks can withstand a certain amount. Anything beyond the system’s capabilities will trigger the pressure relief valve.
However, a faulty valve may not open, causing more pressure to build inside the equipment. Without relief, the tank will explode.
The valve isn’t the only way pressure can build up inside a water tank. High internal temperatures can be too much for the heater to contain due to increased pressure from thermal expansion. Excessive sediment at the bottom of the tank could also prevent the heater from warming the water quickly, forcing the system to overheat, build pressure, and cause tank deterioration.
Corrosion
Even rust could be problematic. Tanks have metal anode rods, which are supposed to develop rust before the heaters. If an anode rod deteriorates, the tank will soon follow.
If you notice brown or discolored water pouring from your taps, it could be due to a rusty rod and tank.
Warning Signs of a Possible Water Heater Explosion in Norfolk
Now that you know the answer to “What causes water heaters to explode?” you must learn the warning signs of impending danger. They include the following:
- Leaky or open pressure relief valve: Since it only opens to relieve pressure when necessary, it should never stay open. If it does, the valve will leak, which indicates massive water heater pressure buildup beyond the tank’s capabilities.
- Constant popping noises: Does your equipment make popping sounds all the time? If so, the tank has a sediment buildup, which is causing micro explosions.
- Shaking appliance: Shakes or movement are clear indicators of equipment failure because tanks never move unless the pressure inside them is too high. When the movement starts, an explosion could happen at any time, so turn the heater’s power off and schedule a replacement immediately.
- Rotten egg smell: Gas has an additive that gives it a sulfuric odor. So, if you smell rotten eggs, contact a Norfolk plumbing expert for an immediate heater inspection.
How Can You Ensure Residential Water Heater Safety in Norfolk, VA?
Your safety is crucial; you don’t want to compromise your household due to improper water heater maintenance. Follow these steps to ensure optimal performance and stay safe:
- Maintain the right temperature range: Setting water heater temperatures too high increases the risk of danger. Keep the temperature between 120 and 125 degrees to keep the pressure in check.
- Install a functional pressure valve: Another way to ensure optimal pressure is to correctly install a pressure valve as soon as you notice problems with your existing device.
- Schedule professional heater service: Heaters need annual cleanings and flushings to keep them safe and functional. Don’t forget to book the appointments with a qualified professional in Norfolk.
If it’s time for a new water heater, consider installing a tankless model. Since water heater malfunctions typically cause explosions in the tanked varieties, you won’t have to worry about this problem with a tankless upgrade.
