This is true for gas heaters (actually it's usually a physical valve that opens on thermal expansion, not a sensor). This prevents a blown pilot from being a safety concern, but it's a pain to manually relight them.
I know of no gas stove that has such a feature, though.
- ams6110 8y agoGas water heaters have this, as do older gas furnaces (any newer furnaces will have electronic ignition not a standing pilot). For kitchen stoves, most have electronic ignition as well. For an older stove, the amount of gas released from an unlit pilot is not significant enough to pose a danger.
- azernik 8y agoThe issue isn't pilot lights for the oven itself; it's the stovetop. Most of the ones I've seen have individual electric lighters for each burner, which must be semi-manually activated (by turning the knob past "maximum" to a "light" setting until it catches). If you turn it to on without lighting it, or turn it off enough to put out the fire but not enough to completely cut off gas flow, you'll get a constant gas leak.
- adamcharnock 8y agoI'm in the UK and I'm pretty sure every gas stove I've ever used has had this feature. The exception being camping stoves which I think may not have had it.
- snthd 8y agoThe gas safety valves I've read about aren't physical, but are actually electric. They use a thermocouple to power an electromagnet in the (sprung) safety valve. Presumably this allows the safety valve to be located further away from the heat source reducing the risk of thermally-induced failure modes.
