Dr. Infrared has a dual heating system and a removable filter that is designed to help the unit last for years.

DeLonghi – Best Portable Oil Filled Radiator

Buyer's Guide for Bedrooms

Winter is coming, and your bedroom is not ready. Space heaters work best as a supplement to central heating and can lower your bill all season long. Keep your room toasty by adding some extra warmth this year, and you’ll never go back.

Types of Heaters

There are many space heaters out there, and each is constructed with different features that work best for certain circumstances and heat up the room in various ways. Most of them are electric, 1,500-watt heaters.

They should warm up quickly—you should notice a difference in 10 or 15 minutes. They are not magic-makers, so you can not expect them to heat your room by more than a few degrees or replace a central heating system. If you are just looking to save a bit of money on your bill and feel added warmth, a space heater can easily accomplish those things.


Most are familiar with this type of warmer, often called a radiator. It is an electric heater that heats up oil through a current, and then the warmth “radiates” around the surrounding area.

Infrared heaters use a bit more science in their construction; rather than heating up the air around them, they emit radiation that warms whatever it touches (your skin, the couch, etc.), much like the sun. These heaters work well in large rooms and open spaces because they can heat larger spaces quickly.

These are going to be more expensive; however, they have a lot of benefits that may be worth it to you. Besides being more energy-efficient, they are often safer than other models because the warming elements do not get ultra hot. They also don’t dry out the air because they don’t need to circulate heat.

These use convection currents that heat up some kind of element, often coils or a ceramic plate. As the element heats up, it slowly expands across the air in the room evenly, starting from the air closest to it.

Many of these types have fans to help circulate the air more quickly because, without them, it could take a while to heat up a large space. Although it may take longer to heat, convection is your best option for keeping a room warmer for longer, so they are more energy-efficient than radiant heaters. Generally speaking, ceramic plates get hotter and work more effectively than coils.


Micathermic heaters use both radiant and convection methods to warm the room; the warming elements are covered in thin layers of mica, which conducts a lot of heat. These are usually more compact and unobtrusive than other warmers.

Features to Look For

Quite a few factors go into shopping for a space heater, so let’s break down some of them to make sure that you are purchasing the right one.

Size and Type

First, plan out where you are going to put your space heater. If your room is large and open, you might need to go with a bigger, convection type warmer. This type would also be best if you are using it often or as a main source of heating during the winter.

Smaller, closed-off spaces would be fine with a smaller unit or a radiator. It is ideal if you only want to heat one section of the house, as well.

Timer and Automatic Shut-off

Most heaters nowadays have an automatic shut-off feature for safety and efficiency reasons; after it has been on for so long or starts to overheat, it turns off.

Timers are another awesome factor that you may want to look for. You can easily set the amount of time that you want the heater to be on for, and it will automatically turn off when the timer runs out. This can save you a bunch of money on your bill.

Tip-Over Protection

Just in case your heater tips over, make sure that your model has an auto-shutoff feature that triggers when this happens. This will keep you and your family safe.


The vast majority of products you will find out there are rated 1,500 watts, which works well in a variety of rooms and are pretty powerful. Some may be lower, around 750, and many people use these for personal heaters at work or in bed.

Thermostat and Controls

Most products come with different heat settings that you can toggle between to achieve your desired temperature. Two settings of “high” and “low” are the most usual, but some units come with exact temperature options. So, if you like your room at precisely 77 degrees, you can do that.

Throughout the duration that it is on, it should stay at your desired heat level. Units with more control options usually come at a higher cost, but it might be worth it if you are picky about how your room feels.

Power Cord

To be able to move your unit around to the perfect spots, you are going to want to have a heater with a long cord. This way, it can maneuver around furniture and plug placement, and you will not have to use an extension cord (which is not recommended due to safety reasons).


A noisy model could easily get in the way of a good night’s sleep in the bedroom or pleasant conversation in living spaces. Generally, units with fans are louder than those without, but most are constructed to have low noise levels.

Ability for Fan Only

If you want to use your space heater year-round, check to see if it has a fan-only option. This turns off the heating element and just circulates the air.

Ease of Portability

Plan on moving your unit around the house? Portability will be key. Models that are smaller and lighter with wheels or a handle will be the easiest to transport.

User Manual

Make sure to read through the instruction manual before using it, as it will contain important safety and setup directions.

Seasonal Availability

Once it starts getting cold, space heaters start flying off the shelves. To make sure that you get the model that you want, start looking before winter comes.

Safety and Important Considerations

General Fire and Safety Information

Portable models can be dangerous; when used incorrectly, they can start fires. In fact, they are the culprits of 44 percent of house fires from 2012 to 2016. Don’t worry—as long as you follow proper safety guidelines, you and your family should be safe.

Be sure that you purchase a unit that has safety-organization verification. In the United States, heaters will have a label from UL or ETL, and Canadians should look for CSA or ULC. These organizations test and verify the product’s safety.

Make sure that you fully read the instruction manual before using your heater, and only purchase those with an automatic shut-off feature. Accidents happen, and anyone could forget to turn off the heater before leaving the house. Even where you place them matters; flammable materials can start a fire when getting too warm, and pillows or curtains can fall on top of them causing potential danger.

But by following safety precautions, and only buying heaters with safety verification, you can rest easy—and warm.

Leaving the Room

You should never leave your heater unattended while it is on. Kids and pets can particularly be an issue; they could accidentally knock them over or push flammable things on top of them. Try to turn off your heater before leaving the room.

Running Them Through the Night

Again, units should never be left unattended, and most people are not very attentive while they are sleeping. Although many products have automatic shut-off features when overheating, you do not want to count on them just in case. Plus, older homes can have issues with wiring and may start a fire while heating up the walls.

If you are concerned about your room being cold, try warming it up before you go to bed for an hour or so. Convection heaters will do the best job keeping your room warmer for longer.

Where They Should Sit

Keep your unit at least two feet away from any flammable materials, including upholstered furniture, pillows, and bedding. Make sure that nothing would be able to fall on top of it, such as curtains blowing in the breeze or your kid knocking over a blanket. Avoid putting your warmer on top of any rugs or carpet, and keep them on a solid, flat surface.

Following these tips should keep your family as safe as possible.

Energy Efficiency

Besides keeping you a bit warmer, a huge benefit of portable heaters are their energy efficiency. When using a space heater, you can usually lower your bill by quite a bit, but you will have to be sure that you are choosing the right option for your space. If you have a large room, radiators will have to be on a lot longer than other types of warmers, meaning it will cost you more.

If you live in an extreme climate or are using multiple heaters in different rooms, it will probably be more cost-effective to use a central heating system instead. But those that live in places that do not get extremely cold and are looking for a little extra warmth can benefit from using a space heater.

Helpful Safety Tips

The main goal is to keep you and your family safe and warm, right? Both of these things are attainable, but here are a few tips to follow so that you can be sure.

Make sure to unplug your heater while not in use; turning it off and unplugging it is important. Water can also be dangerous, so avoid placing your warmer in the kitchen, bathroom, or anywhere that water might come into contact with it. Inspect the power cord before plugging it in every time you use it and do not use an extension cord—damaged cords are the most common reason that fires begin.

When your heater is on, stay in the same room to keep an eye on it and avoid any possible fire issues, and make sure that children and pets stay away, especially from heating elements; if they touch it, they can get burned or knock it over.

Your space heater takes care of you on the coldest days, so you must take care of it and return the favor. Wipe down your heater regularly to keep the dust away because it can become flammable. It is important to keep it clean and store it in a safe, dry place.

When wrapping up your cord, be sure to not damage it and wrap it loosely. And when you do take it out of storage, be sure to inspect the cord before plugging it in.
