Piezo Igniter
A piezo igniter is a device used in gas-powered HVAC systems and water heaters to ignite a gas mixture without external electrical power. It relies on the piezoelectric effect, where pressure on a crystal generates a spark. Piezo igniters are reliable and durable, commonly found in gas stoves, water heaters, and some furnaces.

Quick Facts
How Piezo Igniter Works
Pressure creates a spark to ignite gas safely.
Real-World Application
A homeowner presses a piezo button on a gas water heater to spark the pilot and start heating without electrical ignition.
Pro Tip
Keep the igniter tip and surrounding area clean so the spark can reach the burner reliably.
“Keep the igniter tip and surrounding area clean so the spark can reach the burner reliably.”
Important Things to Keep in Mind

Did You Know?
The piezoelectric effect was discovered in 1880 by Jacques and Pierre Curie.
FAQ
Why won't my piezo igniter spark?
Common causes include debris buildup, worn parts, or a misaligned spark gap.
Can piezo igniters be replaced?
Yes. They are often inexpensive and can be replaced to restore ignition.
Is a piezo igniter better than electronic ignition?
It is simple and power-free, but electronic ignition can offer more features and diagnostics.
