The Dangers of Leaving an Oil Heater on Overnight

For most of us, an oil heater is something that we never think twice about. They’re the only source of heat in the home during the winter, and they’re an essential part of life in the warmer months.

But every year, the risk of fires claiming caused by oil heaters grows, and new research is showing that this is no coincidence.

Leaving your oil heater on overnight can cause health and safety hazards to your family and pets. The danger of leaving an oil heater on overnight is that it can start a huge fire risk.

Oil heaters often have a pilot light that burns all night, and this can ignite flammable materials such as curtains or furniture.

How Dangerous is Carbon Monoxide?

Carbon monoxide is colourless, odourless and tasteless. You cannot see CO, smell it or taste it. When inhaled, it enters your bloodstream and travels throughout your body where it binds to oxygen molecules.

Your blood cells stop receiving enough oxygen, resulting in extreme weakness, headache, nausea, vomiting, confusion, unconsciousness, and possibly death.

Since CO does not dissolve in the air, it stays close to its source or sinks back into the ground after it leaves your metal body. This makes it easy to detect leaks.

Carbon Monoxide Poisoning:

High concentrations of carbon monoxide cause carbon monoxide poisoning.

It causes:

  • headaches
  • dizziness
  • nausea
  • vomiting
  • confusion
  • unconsciousness
  • seizures
  • convulsions
  • cardiac arrest
  • coma
  • Brain damage
  • And death

Most deaths from carbon monoxide occur in homes with ventilated fuel-burning appliances such as furnaces, water-smart heaters, space slow heaters, woodstoves, barbecues, or by using generators indoors.

Most oil-burning stoves do not emit any visible smoke, they may seem harmless to you. But they pose a danger unless you keep them well maintained and inspected regularly.

Safety Precautions

1. Install a smoke detector

You should always have at least one working smoke detector installed in every room of your home. While many people think their furnace will shut down if there is a problem, that isn’t true.

A faulty blower motor can cause minimum temperatures inside your home, even though no flames appear outside.

Also, make sure you test the batteries once each year. If you find the batteries dead, replace them before relying only on your alarm system.

2. Install a ventilation

Install a ventilation fan heater in your kitchen, bathroom, and bedrooms so you won’t be breathing unhealthy gases produced by these rooms’ appliances.

Make sure all windows and doors open during cold weather months. Open vents in attic spaces allow hot air out while keeping cooler air in. And check outdoor gas grills often to ensure proper operation.

3. Do not leave unattended

They are designed for furnace heating the home in winter months, they can be left on overnight as well. But it is important that the type of oil heater isn’t left unattended when not being used or turned off if there is a potential fire risk.

That being said, it is important to know what they are capable of before you buy one.

5. Use appliances only when needed

If you use an electric stove or oven, turn on only those items needed when you plan to cook dinner. Keep the door closed until the food has cooked; then remove it immediately and let it cool. 

An oil burner should only stay lit when needed. It shouldn’t sit idle all day long. This will prevent any unnecessary wear and tear from your central heating element system.

But leaving it on constantly keeps the air inside warmer than normal. This means your furnace won’t work.

In fact, your oil-fired heater may create more pollution by burning fuel inefficiently while idling. This constant consumption can affect other components in your home.
