How to Maintain & Clean the Combustion Chamber of Your Oil Boiler

by Amy Henry

If you have an oil boiler in your home with a hot water system, then you may need to complete a bit more maintenance than if you had a gas or electric appliance. This fact is directly related to the oil fuel and how it burns, flows, and leaves deposits behind. In general, you will need to clean parts of the system. This is wise when the boiler cycles too quickly, fails to turn on, or does not produce enough heat.

To learn more about oil boiler cleaning and maintenance, keep reading to find out how to clean the interior combustion chamber.

Deal With Rust in the Combustion Chamber

Oil boilers contain a central space inside the system called a combustion chamber. This chamber is constructed out of steel and lined with a type of insulating material called ceramic fiber. This fiber is needed to protect the walls of the steel chamber. Temperatures inside the chamber can exceed 4,000 degree Fahrenheit, but steel can degrade and melt at these temperatures. The ceramic fiber that lines that steel can withstand temperatures around 4,700. Sometimes, this ceramic material becomes encrusted with bits of rust, and this interrupts the heating function of the boiler system.

The rust forms, because heat rises to warm the water that runs through the steel lines sitting on top of the combustion chamber. Moisture is created when the oil is burned and the water creates oxidation across the outside of the pipes. The rust then breaks free and falls down into the combustion chamber. 

Clear the Rust

The rust must be removed from the combustion chamber to maintain the boiler's ability to heat the home. You can reach the interior by opening the front door of the unit. Attached to this door will be the motor, oil pump, blower, and the transformer for the unit. The door itself is hinged on one side, and it opens with the loosening of on or several bolts on the door. Loosen the bolts with a socket wrench and pull on the door gently. If the electrical wiring connected to the transformer or motor is preventing you from doing this, then gently pull the wiring out from its plug or socket.

Open the door wide once you are able to. Also, look to see if you can release the top cover of the boiler by releasing screws or bolts. Look for a series of coiled steel pipes inside. Use a wire brush between these pipes to knock loose any accumulated rust. Afterwards, use a shop vac or the hose attachment on your regular vacuum to clear the rust from the combustion chamber. Make sure not to dislodge the ceramic fiber when doing this.

Clean the Nozzle

After the majority of the rust is removed, you will want to clean the spray nozzle that sits just inside the combustion chamber. This nozzle releases oil into the chamber at a consistent rate so it can be burned properly and efficiently. A small hole sits on the end of this nozzle, and it can become encrusted with rust or solidified oil debris. A dirty nozzle can cause firing and heating issues, so it must be cleaned at the same time as the rest of the combustion chamber.

The oil nozzle will be seen on the back side of the chamber door. Use a cotton cloth to wipe the front of it clean. Place a small amount of rubbing oil or mineral spirits on the end of a cotton swab and gently clear the hole of the nozzle. Wipe the sides of it as well and look for soot or rust debris on the two metal prongs that surround the nozzle. These prongs release a spark to light the oil coming out of the nozzle, and you should clear debris away if you see it.

After the nozzle and electrodes are cleaned, close the door to the combustion chamber and replace the bolts. Your heating system should fire and heat your home effectively at this time. If it does not, then make sure to contact heating specialists like Avery Heating & Air Conditioning so the boiler issue can be located.
