Should Your Pilot Light Always Be On?: 1 Minute to Understand Your Pilot Light Needs

The pilot light in many older gas appliances—such as furnaces, water heaters, and fireplaces—serves as a small, constantly burning flame used to ignite the main burner when needed. You might be wondering if this pilot light should always be on, or if there are times you should turn it off. The short answer: for appliances relying on a standing pilot (not electronic ignition), the pilot light typically should remain on during periods of use for both safety and functional reasons. However, during extended periods when the appliance won’t be used (like summer for a heating furnace), it can be safely turned off to conserve gas and reduce minor risks.

From a safety standpoint, the pilot light acts as a continual ignition source. Turning it off when not using the appliance can prevent unintentional gas buildup, but it’s crucial to fully follow the manufacturer’s instructions for relighting the pilot safely. On the other hand, leaving it on throughout the year means a consistent minimal gas flow and minimal heat output, which, over months, can add up in both cost and energy use.

As a designer, I always consider how essential home systems, like heating and water, fit into the bigger picture of comfort and function in your space. Upgrading appliances with older pilot lights to newer models using electronic ignition (sometimes featured in room planners and design tools) not only improves safety and efficiency but also streamlines the aesthetics and reliability of your home. Tools like a room planner help you visualize and plan for such functional upgrades as part of an integrated design solution.

Tips 1:

For energy-conscious homeowners, consider swapping out appliances with standing pilot lights for modern, more energy-efficient options. This aligns both with a safer environment and a more sustainable home lifestyle.

FAQ

Q: Should a pilot light always remain lit?

A: If your appliance uses a standing pilot and is in active use, yes. If not used for long periods, it’s safe to turn off—just be sure you know how to relight it safely.

Q: Does leaving the pilot light on use a lot of gas?

A: Typically, it uses a small but steady amount of gas, which can add up financially and environmentally over a year.

Q: Is it easy to relight a pilot light?

A: Most are fairly easy to relight with instructions from the manual, but if you’re unsure, consult a professional.

Q: Are there modern alternatives to pilot lights?

A: Yes. Modern appliances often use electronic ignition, which only draws gas when needed, improving efficiency and safety.

Q: Should I upgrade if my appliance still uses a standing pilot light?

A: For many homeowners, upgrading can mean better energy efficiency and peace of mind, especially when planned as part of an overall home design update.
