Furnace and Boiler Oil Filters - Oil burner oil filters are important to keep trash out of the burner gun and plugging the nozzle. A dirty filter can also choke the system from firing properly by preventing the correct amount of oil flow from reaching the nozzle. Oil furnace oil filters or oil boiler oil filters should be changed on at least an annual basis. More if the oil or oil tank is of poor quality. It is also recommended that the oil furnace or oil boiler be shut down when oil delivery is made.

Gas Furnace Components 2 - Gas Burners - Depending on the type of gas furnace and how the gas furnace was engineered will depend on the type of gas burners. Inshot burners generally shoot a flame into the combustion chamber where an induced draft exists. For sealed combustion chambers a forced or induced draft will exist.
There are burners with precisely drilled holes in them. Then there are slotted gas burners that extend into the combustion chamber and generally have induced draft combustion chambers. However, these can also have forced draft combustion chambers if the combustion chamber is sealed. The size of these holes and slots in gas burners will also depend on the altitude and capacity of the furnace. (more…)

Outside All Weather Boiler - Outside all-weather boilers are used in circumstances where it is not possible to install the boiler inside a mechanical room or anywhere in the building. There some considerations one needs to take into account about having an outdoor boiler especially if it is for a residential application. (more…)

Oil Controls Burner - The oil burner and oil controls provide the main source of heat for this oil furnace. The oil burner comprises an oil pump, an oil pump, a burner electric motor, a burner blower, a step-up transformer, an oil ignition control, an oil burner gun, and an oil nozzle (inside not viewable here).
The burner electric motor is directly linked to the blower and the oil pump and when the electric motor starts (controlled by the ignition control) the pump begins pumping oil while the blower provides primary air to the combustion chamber. (more…)

Gas Furnace is Making Too Much Noise - Richard, my gas furnace makes a lot of noise when it is running and it is somewhat annoying and sometimes bothers me when I am sleeping. It is installed in a closet close to my bedroom. What can I do to fix this gas furnace that is making too much noise? I’m growing to hate my noisy gas furnace. Jenny
Jenny, sorry to hear about the noise your gas furnace is making. I know an overly noisy gas furnace can be irritating. All gas furnaces make some noise when operating and we can break it down into three different noises. Depending on which noise your furnace is making will depend on a fix to your furnace making too much noise. (more…)

Oil Furnace Condensation Problems - This Oil Furnace has flue gas condensation problems as one can see from the white residue forming on the front of this oil furnace. This problem occurs when the flue gases are not hot enough to rise above and out of the flue. (more…)

Honeywell Oil Burner Ignition Control | HVAC Heating - This Honeywell oil burner ignition control controls the oil burner sequence of operation. On a call for heat from the thermostat, the oil burner ignition control starts the burner blower. this mechanically interlinked with the oil pump.
The blower blows air into the combustion chamber and the oil pump pumps oil to the burner’s nozzle. The step-up transformer is energized and applies a very high voltage spark to the burner’s ignitor. When the flame is detected it is immediately detected by a cad cell eye which recognizes the light produced by the flame inside the combustion chamber. (more…)
