paranoid question

dumbengineer

i have a dual-water heater gas tank. if one of the tanks' "fire" dies, i wouldnt notice it coz the other tank will still supply hot water in my house.

i guess i'm just being paranoid, what are the chances it will cause fire or carbon monoxide poisoning?

i'm comparing it to gas oven left "on" but without fire. gas will escape and may fill up the room which is dangerous.

oh'mike

There are safety devices built in that SHOULD keep it from blowing up---if is not working tourn it to "OFF' and shut off the gas to it----

I"m assuming one which supplies hotwater for heat and hotwater for domestic use.

If the gas was flowing you would smell it. You can also get combo detector that will detect CO, propane and natural gas.

Shouldn't it have individual thermocouplers to prevent that from happening? I had a similar fear until I found out what a thermocoupler was and what it did.

tnx

Thermocouple

• The thermocouple is a safety device that shuts off gas when the pilot light goes out. It's generally part of the electrical field that generates an electric current by producing heat. Thermocouples are predominantly made of two U-shaped conductors of similar metals which create a circuit to control valves and relays. In most devices, such as water heaters, furnaces and gas fireplaces, thermocouples are located near the pilot light. The thermocouple controls the main gas valve that permits gas to flow to the pilot light. Once the pilot light extinguishes, the safety device shuts off gas flow. The thermocouple does not open the gas valve unless the pilot light is lit to prevent gas from needlessly flowing to the device and haphazardly escaping into the air.
