Wet water heaters: everything you need to know to stay safe and save money

Water heaters are essential appliances in our homes, providing us with hot water for showers, baths, and other daily tasks. However, one common concern is whether water heaters can get wet.

The answer is yes, but with some important caveats. Water heaters can withstand occasional splashes or leaks, but prolonged exposure to moisture can lead to damage and safety hazards.

Understanding the Risks of Water Damage

There are several reasons why water damage to water heaters is a concern:

• Electrical hazards: Water can conduct electricity, increasing the risk of electrical shocks or fires.
• Corrosion: Moisture can corrode the metal components of the water heater, shortening its lifespan.
• Mold and mildew: Dampness provides a breeding ground for mold and mildew, which can affect air quality and health.
• Gas leaks: If a gas water heater is exposed to water, it can cause gas leaks, which are highly dangerous.

Mitigation Strategies for Water Exposure

To minimize the risks associated with water damage, there are several steps you can take:

• Proper installation: Ensure that the water heater is installed in a dry location, away from potential water sources.
• Drip pan installation: Place a drip pan under the water heater to catch any leaks or condensation.
• Insulation: Insulate the water heater to prevent condensation from forming on its exterior.
• Regular maintenance: Inspect the water heater regularly for leaks, corrosion, or other signs of water damage.

Types of Water Heaters and Moisture Resistance

Different types of water heaters have varying levels of moisture resistance:

• Electric water heaters: Electric water heaters are more susceptible to water damage due to their electrical components.
• Gas water heaters: Gas water heaters are less susceptible to water damage, but prolonged exposure can still cause corrosion.
• Tankless water heaters: Tankless water heaters are the most resistant to water damage, as they do not have a storage tank that can leak.

Emergency Response to Water Exposure

In the event of a water leak or spill near your water heater, take the following steps:

• Turn off the water supply: Locate the water shut-off valve and turn it off to stop the flow of water.
• Turn off the power: If the water heater is electric, turn off the circuit breaker or fuse.
• Contact a qualified technician: Do not attempt to repair the water heater yourself. Call a licensed plumber or electrician to inspect and repair the damage.

Prevention is Key

Preventing water damage to your water heater is the best way to ensure its safety and longevity. By following these tips, you can minimize the risks and enjoy reliable hot water for years to come:

• Keep the area around the water heater dry and free of moisture.
• Check for leaks regularly and repair them promptly.
• If you notice any signs of corrosion or damage, contact a qualified technician immediately.
• Insulate the water heater to prevent condensation from forming.
• Follow the manufacturer’s instructions for maintenance and care.

Questions You May Have

Q: Can I install a water heater in a bathroom?
A: Bathrooms are typically not ideal locations for water heaters due to the high levels of moisture. However, if you have no other option, ensure proper ventilation and take extra precautions to prevent water damage.

Q: What should I do if my gas water heater gets wet?
A: Turn off the gas supply immediately and call a qualified technician. Do not attempt to operate the water heater until it has been inspected and repaired.

Q: How long will a water heater last if it gets wet?
A: The lifespan of a water heater that has been exposed to water damage will depend on the severity of the damage and the type of water heater. However, even minor water exposure can shorten the lifespan of the appliance.
