Water condenses from the air inside your tank and sinks through the oil to the tank bottom where it forms an acidic sludge that causes random pitting and rusting. Tank-Guard® attacks only the acidic sludge, safely neutralizing it to protect your tank against leaking.

No Heat Check List

  • Check that your thermostat setting is at least 5 degrees higher than your current room temperature. Note, some thermostats also need to be set to "Heat".
  • Check the batteries in your thermostat to see if they need to be replaced.
  • Check to see if the power switch near the system is set to the "ON" position. Note, there may also be another emergency power switch that controls the system's operation.
  • Make sure the circuit breakers are on. It is common for a breaker to trip. The circuit breaker box looks like a metal wall cabinet. It's usually located in the basement or utility room.
  • Check the amount of oil in your tank. If you have an aboveground tank, an attached gauge will show you the level, like a fuel gauge in a car. If the tank gauge reads less than 1/8 full or appears to be empty, you may be out of fuel.
  • Reset your system. Press and hold the reset button on the burner for 3 seconds. This will reset your unit and may restore your heat. If your system does not start after you push the reset button, DO NOT PUSH IT AGAIN. It could cause the combustion chamber to flood with oil and result in a lengthy and costly repair.
  • If you still do not have heat, contact the office 24 hours a day, 7 days a week.
