Are you wondering how long to hold the pilot light on your gas water heater? It’s a common question that many homeowners have, and for a good reason. After all, the pilot light is the ignition source for your water heater, and it needs to run for a specific amount of time to ensure proper functioning.
In this article, we’ll discuss everything you need to know about how long to hold the pilot light on your gas water heater, including the advantages and disadvantages, FAQs, and more. So, let’s get started!
Introduction
Before we dive into the details, let’s first understand what a pilot light is and how it works.
A pilot light is a small flame that burns continuously in your gas water heater’s combustion chamber. It ignites the burner, which heats up the water and provides hot water to your home. The pilot light is essential to the proper functioning of your water heater, and you need to know how long to hold it to ensure your unit works correctly.
There are several factors that determine how long you should hold the pilot light, such as the water heater’s age, type, and size. Generally, you need to hold the pilot light for 30 seconds to 2 minutes, depending on the type of water heater you have.
The Different Types of Gas Water Heaters
Before we go into detail about how long to hold the pilot light, let’s first take a look at the different types of gas water heaters:
| Type of Gas Water Heater | Description |
|---|---|
| Standard Tank Water Heater | Stores hot water in a large tank and continuously heats the water to maintain a constant temperature. Typically, pilot lights run continuously in this type of water heater. |
| Tankless Water Heater | Heats water on demand when you turn on hot water taps. Typically, pilot lights only run when the unit is in use. |
| Condensing Water Heater | Similar to standard tank water heaters, but with added features to increase efficiency. Typically, pilot lights run continuously in this type of water heater. |
Now that we have an understanding of the different types of water heaters let’s look at how long to hold the pilot light on each one.
How Long to Hold Pilot Light on Gas Water Heater
Standard Tank Water Heater
If you have a standard tank water heater, you’ll need to hold the pilot light for at least 30 seconds to 1 minute. This duration gives the gas valve enough time to release the gas and helps ensure the pilot light ignites the burner.
However, some water heaters have a control valve that requires you to hold the pilot light for 2 minutes to allow the thermocouple to heat up and signal the valve to release gas to the burner.
Tankless Water Heater
In contrast, tankless water heaters use electronic ignition to ignite the burner when you turn on hot water taps. The pilot light only runs when there’s an issue with the electronic ignition system. If you need to relight the pilot light, you’ll only need to hold it for 30 seconds to 1 minute.
Condensing Water Heater
Similar to standard tank water heaters, condensing water heaters require you to hold the pilot light for at least 30 seconds to 1 minute. However, some models also require you to hold the pilot light for 2 minutes to allow the thermocouple to heat up and signal the valve to release gas to the burner.
Advantages and Disadvantages of Holding Pilot Light on Gas Water Heater
Advantages
There are several advantages to holding the pilot light on your gas water heater:
- Ensures proper functioning of your water heater
- Helps save energy and lower utility bills
- Reduces the risk of gas leaks and carbon monoxide poisoning
Disadvantages
While holding the pilot light is essential, it also has some downsides:
- Wastes gas and increases your utility bills
- Creates unnecessary wear and tear on your water heater
- Can be hazardous if not done correctly
FAQs
Q: How do I relight the pilot light on my water heater?
A: Refer to your water heater’s manual on how to relight the pilot light. Typically, you’ll need to turn the gas valve to “pilot,” hold down the button to release gas, light the pilot light, and hold the button for at least 30 seconds to 2 minutes.
Q: Can I turn off the pilot light if I’m going on vacation?
A: Yes, you can turn off the pilot light if you’re going on vacation. However, if you’re only leaving for a short period, it’s more efficient to leave the pilot light on.
Q: How often should I relight the pilot light?
A: You should only need to relight the pilot light if there’s an issue with the water heater’s ignition system. Otherwise, the pilot light should run continuously.
Q: What causes the pilot light to go out?
A: Several factors can cause the pilot light to go out, such as a faulty thermocouple, a dirty or clogged pilot light, a gas supply issue, or a draft in the room.
Q: Can a pilot light explosion occur?
A: While rare, a pilot light explosion can occur if there’s a gas leak and the pilot light ignites the gas. It’s essential to follow proper safety procedures when handling your water heater.
Conclusion
In conclusion, knowing how long to hold the pilot light on your gas water heater is crucial for proper functioning and energy efficiency. Make sure you refer to your water heater’s manual and follow safety procedures when relighting the pilot light. If you have any concerns about your water heater, don’t hesitate to contact a professional.
Don’t let a faulty pilot light ruin your day. Follow the proper procedures and enjoy hot water whenever you need it.
