Oil Filled Space Heater Buying Guide

As the weather changes and it starts to get cold, we’re always looking for ways to provide hot air and keep warm.  Rather than just cranking the heat this winter, consider something a bit more energy efficient, something that allows for a more centralized heat source where you need it.  Space heaters are often the perfect fit.  They heat only the area you need heated, saving you money.   More specifically, oil-filled space heaters are quiet, maintenance-free, and they’re portable so you can move them anywhere you need them.  They also have the capacity to heat very large rooms.

What to Look For in Oil Heaters

Of course we’re not all experts in electric heaters, and that’s okay.  It’s something you really don’t think about until you need it, and at that point, you don’t have hours to spend doing too much research.  The good news is that we’ve taken the time to study up on them for you.  

The following is a list of things to consider when you buy an oil filled spaced heater.  We’ll cover what makes them good, along with which features you need and which are just “nice to haves”.

Heating Capacity / Modes

The very first thing you’ll need to consider when making a space heater purchase is it’s heating capacity.  How big of an area are you looking to keep warm and what size heater does that require?  Since we’re specifically talking about oil filled radiators to heat large rooms, you’ll need adequate heating capacity for larger areas.  This usually means a 1500-watt oil filled heater.  This was our threshold for the capacity on the list above.  They do make smaller, often 700-watt heaters, but these are typically used in a very cozy setting like a small office space next to your desk.

Next, the best oil filled space heaters offer multiple heating modes.  So rather than just turning the heater on/off, you can setting it for the amount of heat you need.  This helps with energy efficiency (more on this below), but it’s also needed to satisfy your differing comfort levels.  We recommend sticking with machines that include this feature.

Energy Efficiency

We briefly touched on the energy efficiency of oil filled radiator options above.  There are several reasons why they’re the best choice in space heaters, and this might be the biggest one.  They are very efficient in quickly warming areas of your home where you need it and not where you don’t.  There’s also no forced air, so that means they’re quiet and it saves energy too.  

In addition to oil filled space heaters being inherently energy efficient, modern features like eco mode and multiple heat settings, and adjustable thermostats mean you only use heat when you need it.  This again helps you cut down on your energy bill, ultimately putting more money back in your pocket, and at the same time, doing the right thing for our environment.

Safety Features

If you have small children or pets in your home, you must think about the safety aspect of having a heater around.  The good news is, the best oil filled heaters now have sensors for tip over protection and overheating.  These are both safety features that prevent fires. 

In the past, fires have always been a concern with space heater safety.  While we’ll probably never do away with that concern, making sure you buy a space heater that implements features like these are ensuring you do what you can to help keep your family safe.  It’s also important to keep the heating element away from small children so they don’t burn themselves.

Where to Place a Space Heater

Understanding where to place a heater in your large room is also important.  Ultimately, if located optimally, the heater will help you cover a larger area, thus allowing to you purchase a smaller, less expensive heating system.  As we all know, warm air rises.  This means typically it’s best to place the heater on the floor, doing your best to keep the heat lower.  

The other thing to consider is windows & doors that may be allowing a small draft to enter the room.  Have you ever noticed that when you stand next to a window or door opening, it feels a bit chilly in the winter time?  This is because there is a small amount of cold air finding it’s way through.  It’s most efficient to warm that air almost immediately before you start feeling that elsewhere.  For this reason, we recommend that you place your oil filled heater near the windows of the room, and of course in an area where it will not get tipped over.  Depending on the draft, you’ll want to adjust the heat settings accordingly.

Customer Reviews/Feedback

Looking back at what other customers have said about their purchase of the items you’re looking to buy is the best way to identify good and bad products.  With so much information readily available at your fingertips on the internet, there’s really no excuse to do this 2-minute research that could help you find something great, or perhaps more importantly, avoid a bad buy.

Customers readily offer their feedback over and over at online retailers like Amazon.  Using this free resource is an absolutely awesome way to size up what’s worth spending your money on and what’s not.  Take advantage of this.
