Oil-Filled Heaters Dry The Air

Do Oil-Filled Heaters Dry the Air?

Contrary to popular belief, oil-filled heaters do not dry the air. When these heaters warm a room, the air’s capacity to hold moisture increases, but the actual moisture content remains unchanged.

This phenomenon leads to a drop in relative humidity, making our skin feel drier and possibly causing discomfort in our nasal passages.

It’s essential to understand that any heating source that doesn’t add moisture will have this effect, not just oil-filled radiators.

Relative Humidity Explained:
Relative humidity is the ratio of the current amount of moisture in the air to the maximum amount it could hold at that temperature.

When the room is heated, the air can hold more moisture, but since no additional moisture is added, the relative humidity drops.

Addressing Dryness:
If you experience discomfort due to reduced humidity, consider adding household plants, drying clothes in the room, or using a humidifier.

Sealing any draughty leaks in the room can also help maintain a comfortable humidity level.

What Are Oil Heaters?

Oil-filled heaters resemble traditional radiators in appearance. However, they are smaller. They consist of a series of connected fins or columns.

They may feature open spaces between the columns or fins connected to a base with a control panel in front. Flat panels are found on some oil heaters, but they are uncommon.

Oil-filled heaters, unlike typical radiators, are portable. The link to the household electrical system via a conventional wall socket allows them to be relocated to any room that needs additional warmth.

Many even have carry handles, while larger ones normally have wheels to reposition easily.

What Is An Oil Filled Heater, And How Does One Utilize One?

An oil-filled radiator resembles an old-fashioned radiator (the kind you normally see someone hitting with a wrench on TV), but it is much smaller.

They are made from a series of connected columns or fins, sometimes with open spaces between them, attached at the base and have a control panel in front of them.

A single flat panel is made up of a few oil-filled heaters.

Oil-filled radiators are more movable than ordinary radiators. They connect to your home’s electricity using a standard wall connector, allowing them to be relocated practically anywhere.

Most of the types have carrying handles, and the larger variants have wheels for convenient movement.

The heater’s body and fins are filled with diathermic oil. “Do I have to refill the oil?” is the most often asked question about oil-filled heaters.

No, you don’t have to replenish the oil in an oil-filled radiator, says the answer.

It never runs out because the oil is not used as a fuel but rather as a heat reservoir. It just circulates through the heater for the duration of your use.

Advantages Of Oil-Filled Heaters

Now that you know how oil-filled heaters work, all the benefits of having one in your home or workplace. There is no fan.

A fan blows hot air out into the room from a typical space heater with an exposed heating element. Oil heaters are virtually completely silent.

The thermostat regulates itself, so the most noise it produces is clicking.

  • The air will not be dried. Because you don’t have a fan, the air in your room will not dry out.
  • It saves energy. Electric heaters are nearly 100 per cent efficient, meaning that all energy consumed is directly transformed into heat. A fan motor does not need to be powered by an oil-filled heater.
  • Allow time for cooling. Even after the power has been switched off, they continue to radiate heat.
  • Thermostat-controlled environment. Oil-filled heaters will automatically cycle off and on to maintain a reasonable temperature once the area or room achieves that degree, rather than running continually, saving you money and preventing overheated areas.
  • Oil does not require replenishment. Because the oil isn’t utilized for fuel, it will never need to be replaced.
  • Portable and compact. Oil-filled heaters are small and light, making them easy to transport. Many of them are compact enough to fit beneath a desk.

Non-scorching surfaces make oil-filled heaters some of the safest space heaters available:

  • The metal surfaces become warm to the touch but not hot enough to burn if mistakenly brushed against.
  • There is no visible heating element. The heating element is fully confined within the heater, so it will never come into contact with anything flammable.
  • There are no grilles or vents. There’s no need to worry about dust or debris getting inside an oil-filled heater or fingers poking through an uncovered grill. There’s also no need to worry about restricting air passage through intake and exhaust vents.
  • There is no gas or smell. They are safe to use indoors because they do not burn oil or gas.
  • Safety features are built-in. Overheat prevention and tilt-switches are standard on most models, which turn the heater off if there is a problem.
  • Of course, like with any product, there are certain drawbacks; the most significant is that they take longer to heat up than a fan-forced heater. Because oil-filled heaters must first heat the oil before warming the air around them, this is the case. Fan-forced heaters provide a burst of hot air nearly instantly.

How Does An Oil Heater Work?

Diathermic oil is found inside the fins and bodies of oil heaters.

Because this oil isn’t used as a fuel source, it won’t need to be replaced. Instead, the oil serves as a heat reserve, which will never be depleted. Instead, it keeps circulating through your heater. The following is how an oil heater works:

  • The electricity will be sent into the heater’s resistor. This will convert the electricity’s energy into heat.
  • The oil inside the heater will then absorb the heat.
  • The oil’s warming will begin to move through the columns and fins.
  • The passage of the oil into the heater’s metal fins will transfer the heat. This will result in more consistent surface temperatures.
  • When the metal in the fins heats up, it radiates heat around the space.
  • Due to natural convection, the heat will flow throughout the space.

What Are The Advantages Of An Oil-Filled Heater?

You may be wondering why you should choose an oil heater for your home now that you know how they work. There are numerous benefits, including:

  • They are virtually silent, and the air will not dry out because there is no fan.
  • Energy efficiency – an oil heater converts 100% of its energy into heat. You’ll save money on your utility bills, especially because oil heaters don’t require extra power to run a fan.
  • Slow cooling – oil heaters are even more energy efficient because they radiate heat after turning off the electricity.
  • Thermostat-controlled — rather than constantly running once the room has achieved the desired temperature, the heater will cycle on and off to maintain the desired temperature. This will keep your room at a pleasant temperature while saving you money.
  • Oil will never need to be replenished because it will never be used as an energy source.
  • Portable and lightweight, they may be transferred from room to room thanks to their compact and lightweight design.
  • Although the metal will warm up, it will never become so hot that it burns you. They can also be used safely indoors because no fumes or gas are created. Most models also have built-in safety mechanisms that turn off the heater in the case of a malfunction for your safety.


Hopefully, after reading about Do Oil-Filled Heaters Dry The Air? You’ll be able to decide whether one of these heaters is the best solution for your chilly rooms! Oil-filled heaters dry the air equally as effectively as resistance heaters using a heated surface and convection without using a fan to heat an area.

Ceramic heaters are similar to electric heaters. However, they have a fan. If the air in your home is excessively dry, consider purchasing a humidifier with a water tank to evaporate moisture into the air.

The humidity in the area will be reduced if exiting warm air is replaced with colder outside air. You might also hang some damp towels to add moisture to the space as they dry.

Frequently Asked Questions

Do oil heaters dehydrate you?

While heating the room, oil-filled room heaters do not burn oxygen or lower humidity. They are the greatest options for toddlers and the elderly because they do not dehydrate them. They’re the finest option because they don’t suffocate you or create dry eyes or skin rashes.”

Does an oil heater remove humidity?

Heaters do not eliminate moisture from the atmosphere. Combustion heaters (kerosene, propane) add moisture to the air. However, because hotter air may contain more moisture, the relative humidity can decrease even if the actual humidity does not.

Can you become sick from using an oil heater?

Look for signs of CO poisoning such as headaches, nausea, dizziness, and lethargy. A carbon monoxide detector will give you extra security and peace of mind even if you’ve never been poisoned by carbon monoxide from an oil heating system.

Is it okay if I leave my oil heater on?

Oil heaters are generally safe to leave on overnight. The basic reason is that there is no exposed heating element in them. They’re made to keep the surface from getting too heated. They also contain built-in tip-over switches and timers that will turn off the heater in specific circumstances, lowering the fire risk.
