37. Almost No Appliances Have Pilot Lights Anymore

We are all gas. Stove, dryer, water heater, home heat. They're are all spark ignited. When the demand valve opens a sparker fires. A thermocouple reads a rise in heat (meaning there is a live heater fire) and the sparker turns off.

There is timer in the logic that if the thermocouple doesn't detect heat within a few seconds, it shuts the gas valve again.

Some of our stuff is "newish" but the water heater is at least 15 years old and it works the same way.

The concern you expressed, completely valid, has been engineered out of most systems like that today.
