Pilot light

A pilot flame, also called pilot flame, is an ever- burning, small flame.

Heaters

For gas appliances such as boilers, water heaters, etc., it ensures permanent combustion. If the gas valve of the burner opens, the escaping gas at the pilot flame ignites. A safety pilot interrupts when going out of the pilot gas to the appliance fully. Although the gas consumption is not particularly large, can add up over time considerable quantities. Therefore, an electric spark ignition is used in most modern appliances.

Running costs

The performance of a pilot light is about 60 watts. The hour ie 60 Wh or 0.06 kWh for operation is required, the per month add up to 43.2 kWh. At a price of about 6 cents / kWh ( in 2006) so monthly 2.60 EUR caused to cost of natural gas, or 31.10 euros per year. Pilot flame older boilers and water heaters can consume five to eight times.

The pilot flame bears in winter only limited for space heating at because the heated air is usually passed immediately into the chimney from their immediate environment. It's worth to delete the pilot flame of consumption-based devices (eg domestic hot water thermal bath ) when not in use.

Pyrotechnics

In pyrotechnics, it serves as Zündlicht as a means of ignition. Here, too, are increasingly electric detonators are used.
