Low water cut off:
This is one of the most important parts on a steam boiler. This device has a probe inside the boiler andcwhen it does not detect any water it first shuts the burners off so it stops heating up the boiler. Second if you have a automatic water feed installed it tells the water feed to start feeding water into the boiler until it finally detects water again. Then it stops feeding water and tells the boiler to fire up and run again if there is a call for heat.
If the boiler runs and is heating up without water even for a short period of time this can cause your boiler to crack and the boiler would then need to be replaced. This why it’s extremely important to have a working Low water cut off in your system and always need to mange sure the probe can detect the water level by having your system serviced every year.
Automatic water feed:
This is a optional device you can have installed on your steam system. If your low water cut off doesnt detect water it shuts the boiler down then either sends a signal to a automatic water feed to start feeding water into the boiler or if you don’t have one you would have to manually open the water valve to feed water into the boiler until the light shuts off on the lowc water cut off. If you have a automatic washer feed everything is done automatically and you dont have to physically check on your steam systems water level everything is taken care of automatically.
