Oil Burner Nozzles

If your oil burner in your boiler or furnace is not lighting up, running rough, or not running as efficiently as it could be its highly likely that there is something wrong with your oil burner nozzle.

Its these devices that meters the flow of heating fuel, natural gas, or waste oil (for alternative energy fans) to the combustion chamber.  These nozzles are specifically designed to spray a very fine mist of fuel in a pre-set pattern to be ignited as its coming out.

The pattern, to my knowledge,  is different depending on what type of combustion chamber you have.

The opening on these nozzles is not big at all.  They are extremely small and usually come with a stainless filter at the back opening to filter any moisture or contaminants that have not been filtered out already.  Having said that its extremely easy for oil burner nozzles to get plugged.

The spinner will oftentimes wear on the inside changing the flame pattern.  It happens all the time.  These things are extremely delicate and you would be surprised by how little it takes for them not to be working at 100% efficiency level.

I would highly recommend you get your nozzles changed at least once a year to make sure you have everything working exactly the way it should.  If you get an annual tune up on your heating boiler or furnace they usually change the nozzle, other various filters (oil and air), and drain your tanks.

On a side note you would be surprised by how much moisture builds up in your holding tank where you store your heating oil.  Your may not think there is any condensation in there but water is one of the main culprits in oil burner nozzles clogging up.

There are three types of nozzles from what I know and they are: solid cone, semisolid cone and hollow cone.  You only need to know this information if you plan to change them out yourself.  Please do not try to attempt to do this if you do not know what you are doing.  Me and my business partner will change them out from time to time because the distributor who installed it for us walked us through it step by step.  Because we have a waste oil boiler we try to change them out semi-annually.  Even having said that I sometimes get a professional to do it because I do not like the hassle.

But anyway, you need to know which type of nozzle your boiler or furnace uses because each one of the types just mentioned has a different spray pattern.  You do not want to put the wrong one on!


Oil Furnace From Local Automotive Shop

Here is some pictures of waste oil furnaces I saw today.  I used to give tons waste oil to these guys years ago before I bought my oil boiler because they never had enough to last them throughout the whole winter.  They do mostly automotive work and I assume that when the owner first purchased his oil furnace he thought his business would do more than enough oil changes to provide fuel for it.  Boy was he wrong.

I talked with one of his employees at length and he said that not too long in the winter they have to shut the oil furnace off and switch back to natural gas.  When they get a nice quantity of motor oil they switch back to that. Sounds like a complete waste of time and money in my opinion. Especially when its so easy to get all the used motor you need if you look hard enough.  Any major tire shop, automotive shop, quick lube, or large construction company that maintains its own vehicles will usually generate a couple barrels of oil every month.  All you have to do is ask for it.  They will be more than happy to give it to you.  Its a pain to get rid of it and a lot of these places have to pay to have it picked up.

The guy told me that they have had oil pump related problems and have needed to replace it twice since they have had it.  Now I do not consider myself a totally trained professional but I have tons of experience with these things and I think the oil pump is going out because they keep letting their holding tank run out of oil.  How do you think the oil pump gets its lubrication in a furnace or a boiler?  I think this could be especially true in a furnace because the oil is pumping upwards to the furnace instead of lateral in an oil boiler.  They have not had their furnace that long for them to be having these problems.

Oh, and did I mention that they had to get their oil burner totally rebuilt inside the furnace.  I am witting this post to explain to you what can happen if you do not take care of your investment.  The employee says that they filter the oil and clean it but I have my doubts.  Unless you have a machine that was made on a Monday it will last a long time if you clean it, gets routine tune ups from time to time, and filter the oil going into it making sure as little dirt and moisture gets into it as possible.

Is An Oil Burner Worth The Cost?

I get many questions throughout the month from people asking me two questions.  They are a) what do waste oil boilers/ burners or furnaces cost and b) are they worth that cost?

I think these are very good questions to ask.  Many people today are interested in various forms of alternative energy heating but they also want them to be economically feasible and give some sort of reasonable return.

I can assure you that this form of heating will do both.

How Much Do They Cost?

This is will depend on what type of structure you want to use your boiler (or burner) for.  Are you are going to be heating a home, office building, or small shop?  You are going to find that many companies that make waste oil boilers will have at at least three models for heating small, medium, and large areas.  The larger the area you have the larger your hot water output (for boilers) or air flow (for furnaces) will have to be.

The prices can range from $5,000 all the way to $10,000 for your waste oil boiler, fuel tank, and several optional accessories.  That does not include the installation and set-up.  That alone could cost you an additional $2,000.  Here is the breakdown of my total costs for my personal waste oil boiler.  My basic package was $5,698 but once I added a hot water coil, a 250 gallon workbench holding tank with a furnace stand, a plumbing and hardware package, and tank gauge the total cost came out to be $8,000.  I then had to pay an additional $2,000 for shipping.  Keep in mind that I live in Anchorage so my shipping will be a lot more than everyone else.  So the total cost I paid for my Energy Logic El-200 model ended up being $10,000.  Following that expenditure I still had to pay another $2,000 for the installation of my machine including connecting all the thermostats, pipes, hydronic lines and tubing to my house and my newly build 1,700 two story garage/shop adjacent to it.

There are some lessor models like Lanair that you can get for $4,000-$5000.  Keep in mind that that is just for the base package and you will need to add at least $1,500 to whatever base package you see to make it workable.  I would strongly recommend going with some of the top brands.  These devices are extremely delicate and if you get one of the cheaper models you can be sure to have problems.  I personally am a big fan of Columbia and Energy Logic but there are others that are just as good.  Beckett makes a lot of the components for these companies as well as some add ons you can get like the Beckett heat manager (also known as a fuel economizer).

Is the Cost for an Oil Burner/ Boiler Worth It?

Absolutely!  I have save thousands of dollars in heating cost by having one.  I would not trade mine for the world.  My oil boiler has enabled me to have $10 heating bills in February.  If I had not purchased one that bill with my home and shop would have been at least $400 a month during the wintertime especially when you consider the fact that we had to coldest winter in the last ten years.  I saved at least $1800 just this last winter and because all my heat was free and I had an abundance of waste oil I had the temperature in my home and business at 80 degrees all the time.

I would say that I have gotten all my money back and for many of the people who live in this country the ROI will be fast because your costs of shipping an installation will be lower.  Depending on where you live you should be able to recoup all your money in two to three years.  Your return could be greater if natural gas and heating costs continue to rise at their current levels.
