How to Troubleshoot Common Issues with Commercial Heating Oil Burners

Keep your commercial heating oil system running with Fraticelli Oil & Propane

Using commercial heating oil for your business here in central Massachusetts and southern New Hampshire has all sorts of advantages.

Commercial heating oil produces more heat per gallon compared to many other types of fuels, it is clean-burning and efficient, can help a heating system last longer than it otherwise would and it can be incredibly cost effective.

With all of that being said, a heating system is never flawless, even when it’s fueled with commercial heating oil.

However, you don’t need to sweat it. There are many issues that your average person can fix with a little bit of troubleshooting. Let’s take a look at what some of those are.

What to do about issues with your commercial heating oil burners

When it comes to a commercial heating oil burner, there are some fairly common problems that people may run into. Here are a few of them along with what you can do to fix them:

• Check your fuel levels: If you are low (or completely out of) commercial heating oil, your commercial heating oil powered heating system isn’t going to be able to provide you with heat. So check your fuel supply and schedule a delivery if you are low.
• Take a look at your circuit breakers: If your burner isn’t turning on, take a look at your circuit breaker panel to double check that all the switches are in the ‘on’ position.
• Check your pilot light: A burner will also not turn on if your pilot light is out.
• Look at your drain pan: A heating system that is working properly will automatically drain the water that it removes from the air. Therefore, a full drain pan can be an indication that something (i.e.: a triggered float switch) isn’t working quite right and is preventing your heating system from turning on. If you notice that your drain pan is full, check to make sure your system’s pump is operating correctly.
• Don’t ignore any unusual orders: If there is a strange odor coming from your heating system you may be over firing your unit or you may have something blocking your flue or chimney.

Don’t forget to call in the professionals

The best way to stay clear of any burner issues is to stay on top of your annual tune-up appointments. You can count on a professional to catch any small problems before they turn into large and potentially expensive issues. Annual maintenance is also the best way to help ensure your heating system is working as effectively as possible.
