Oil Column Heaters Buying Guide

Looking to beat the winter chills without spending big bucks? If you’re low on cash, but still want to keep things hot at home, an oil column heater may be just what you need.

This is one of the cheapest and most convenient options in the world of portable heaters. But, what exactly is an oil heater and should you get one? We answer your burning questions in this article.

What is an oil column heater?

What is an oil column heater

An oil-filled column heater is a type of portable electric heater which uses electricity to warm up oil contained inside the columns (otherwise known as fins) to generate heat which is then transferred to the exterior metal column casings and then warms your home via air convection and thermal radiation.

Do oil column heaters use a lot of electricity?

Oil-filled column heaters have been praised for their energy efficiency compared with other types of heaters since they largely transform energy into heat and don’t require power for a fan motor. The small portion of electricity which isn’t converted is alternatively used to power other features, such as LED displays, timers or different heating modes.

Are oil heaters expensive to run?

Oil-filled column heaters are generally the cheapest type of electric portable heater to run. But they’re certainly not as affordable as using reverse cycle air conditioners, especially those designed for small to medium-sized areas, or radiant-convection gas heaters.

Electric heaters tend to have higher running costs because they take longer to warm up compared to gas heaters, for example, which can heat large areas much quicker. That’s why many brands such as Goldair recommend certain oil heaters for larger spaces, compared to less open or spacious rooms where a reverse cycle air conditioner might be more cost-effective in the long run.

6 good reasons to get an oil column heater

If you’re still on the fence about buying an oil column heater, here are some benefits to consider:

  1. Low upfront cost: Oil column heaters aren’t expensive to buy, with options starting from just $15 and reaching up to $400 for high-end models.
  2. No gas or fumes: The process of converting energy into heat doesn’t actually involve burning oil (and clearly not gas or other fumes in other types of units).
  3. Keeps you warm for longer: Oil is great at retaining heat longer than other types of fluids, which is why column heaters are better at ensuring you stay cozy.
  4. Less noise: If the sound of the washing machine and dryer already drives you crazy, don’t worry. Column heaters are known to be quiet performers.
  5. Portable: Oil column heaters come in various sizes and styles. Many are pre-assembled, or at least have a handle, cord storage and castor wheels to help you easily move around the house.
  6. Safer to touch: We’re not suggesting you should run to an oil heater and give it a big hug, but the surfaces you might accidentally bump into are unlikely to get as hot compared to other types of electric heaters. Plus, there’s less risk of anything catching on fire if it comes into contact with the unit since the heating element is sealed inside. All oil-filled column heaters also come with a safety tip-over switch and overheat protection.

Some disadvantages of oil column heaters

There are always two sides to every story. Here’s why it might not be the best idea to pour your money into an oil heater.

  • Uneven heat distribution: Many column heaters don’t have a fan to make sure heat is spread evenly throughout the room, although brands are now starting to add this feature in their latest models.
  • Bulky: While column heaters are technically portable, it’s not uncommon for them to weigh around the 7kg mark or be spread out with more than five fins.
  • Slow to start: While oil heaters are great for long-term use, they need a fair amount of time to prepare. This is because the oil needs to be heated up before it’s transferred into the columns, which themselves also take time to warm up.
  • High running costs: Oil-filled column heaters aren’t the most affordable to run, so whether this factor is a pro or a con depends on how you plan on using your unit. If you’re thinking of using a model with 11 fins in a small room for two or three hours a day, then it might not be worth it.

Is it worth getting an oil-filled column heater?

The beauty of oil-filled column heaters is they’re available at all different price points, ranging between $15 and $400. As a general rule, a model priced at under $200 should still do the job, unless you live somewhere particularly cold. Most brands offer a two-year warranty on oil column heaters, with certain manufacturers, including De’Longhi, offering a seven-year warranty on some models.

But keep in mind scoring a good deal isn’t just about finding the cheapest heater on sale. Your budget needs to take into account how much you’re willing to spend upfront, plus in the long run. Do you prefer to leave your heater on overnight? Oil column heaters are likely to be more useful and cost-effective if you’re planning on leaving the appliance on for longer periods, instead of just a couple of hours while you’re watching TV. Otherwise, you might be in for a nasty bill shock! The other downside to oil column heaters is that you’ll probably be waiting a while for it to heat up too.
