Steam Furnace Maintenance

A steam furnace utilizes a boiler to produce steam; it is composed of several parts. The furnace is the part of the steam furnace that produces the heat; it does this by burning fuel such as oil or natural gas. The boiler utilizes the heat produced by the furnace to convert water to steam. The steam produced by a steam boiler furnace has several uses. It can be used to heat the home or office, power steam engines and more.

A steam furnace has a lot of advantages over other types of heating systems. It has less moving parts; this makes it more durable and reliable and also quite efficient. It quietly provides steady heat that is dust-free. Even though one of the advantages of a steam furnace is its durability and low maintenance, it should still be checked yearly to guarantee operation without problems.


Preventative maintenance procedures should be done to ensure safety, avoid major repairs and replacement costs, lessen downtown caused by unforeseen breakdowns and lessen fuel expenses by improving efficiency. You can do most maintenance procedures yourself.

Summer Maintenance Procedures

The boiler must be drained and flushed to keep the parts working properly and to help prevent damage to the device. All manholes and hand holes should be open and the boiler must be checked for any damage or rust. To lessen the buildup of scale and rust, you should also begin a water treatment program. The water feeding and low water cutoff devices should be disbanded, cleaned and assembled again. The gas burning gear should all be cleaned and the controls regulated. Fuel safety shutoff valves should be checked for leaks; pumps, fans and other mechanical gear should be oiled and the motor operation and rotation should be verified. The boiler pipes should also be checked for leaking and missing insulation. It is advisable to create a log to record the maintenance procedures done.

Winter Maintenance Procedures

Make sure that the boiler room is uncontaminated and that all the air openings, ventilation and louvers are clean and waste-free. The water level of the boiler should also be checked to ensure that it’s not too low since a lot of boiler accidents happen because of a low water levels. The stack dampers should be open and the boiler furnace should be inspected for any unknown material. The flue passes and furnace should be checked for fuel buildup; check the flame height and color too. A blue flame is hotter than a yellow flame. Make sure that the boiler cuts-in and out at the right pressures and right temperatures. The low and high fire proving switches should also be checked. The safety relief valve needs to be examined manually; this can be done by lifting the level with your hand when the pressure of the boiler is half of the valve set pressure. Check the smoke, soot and the flame’s condition and make sure all flame detection devices are working properly.

Proper maintenance of your steam furnace is the best way to avoid injuries and accidents and keep it working efficiently.
