4 Primary Controls On A Residential Steam Boiler

If you just purchased a home that has a steam boiler in it, you need to familiar yourself with how the steam boiler works so that you can take proper care of it. Here is a quick guide to the basic controls found on most residential steam boilers, and what each control is responsible for.

#1 Pressure Gauge & Regulator

This gauge plays a very important role in monitoring your steam boiler. It is in charge of measuring the pressure that your boiler is exerting. It makes sure that your boiler stays within the allowable and safe pressure limits while it is in use. If your boiler exceeds recommended pressure levels, your regulator will stop the supply of fuel to the boiler until the boiler returns to normal and safe pressure operating levels.

The pressure gauge and regulator ensure that your boiler operates within safe pressure levels and act as a fail-safe, shutting off your boiler when the pressure levels are not safe.

#2 Temperature & Pressure Relief Valve

The temperature gauge keeps track of the internal temperature inside of your boiler and allows you to check and see what the temperature is like whenever you want.

The temperature and pressure relief valve are also another fail-safe built into your boiler. If the pressure gauge and regulator fail for some reason, this valve will release steam out of it to help alleviate both the pressure and temperature levels inside of your boiler.

#3 Water Level Sight Glass

This tube is made of glass and allows you to see the water level inside of your boiler. It generally also has marks on it so you can better quantify the level of water inside of your boiler at all times. Your boiler needs to maintain consistent water levels in order to create the steam that it needs to function properly.

#4 Low Water Cut-Off

Finally, most steam boilers also have a low water cut-off control. This control is designed to work automatically, although it can generally be manually triggered as well. If the water level in your boiler drops below safe operating levels, then the low water cut-off should turn off your boiler. This will prevent your boiler from becoming destroyed due to low water levels. 

If you are unsure where any of these valves and controls are located, consult the owner's manual that hopefully came with the home. If the owner's manual didn't come with the home, find the name of the manufacturer on the steam boiler and request an owner's manual directly from the manufacturer.
