Bedroom Space Heater Buyer’s Guide

Because there are so many different types of space heaters, it can be overwhelming to try to narrow down your favorites. In the following sections we’ll describe the different models of electric space heaters and the benefits of each, focusing especially on the models that are best for the bedroom. We’ll finish with some buying considerations and safety tips.

How Do Space Heaters Work?

Space heaters are portable heaters designed to heat small spaces. Many people use electric space heaters to save money on energy bills, as they allow you to heat just one room at a time instead of the whole house.

There are several different kinds of space heaters but in general, they provide heat in one of two ways: convection or radiation. Convection space heaters warm up the air, while radiation space heaters give warmth to anything they touch. Some space heaters use a combination of convection and radiation.

Space heaters are not a replacement for central heating. If you need to heat multiple rooms, it’s generally cheaper to use central heating. But if you just need to warm up a small space, then a space heater can provide the perfect solution.

How Can Space Heaters Help Me Sleep?

The optimal temperature for sleep is between 60 and 65 degrees. Trying to sleep in an environment that’s too warm can have negative effects on the quality of your sleep. However, many people have trouble falling asleep if they are cold.

One solution is to heat the bedroom with an electric space heater and then turn it off when you’re about to fall asleep. The room will stay warm for just long enough to help you fall asleep, but it will cool down as the night progresses, helping you sleep more soundly. Of course, if your room drops below 60 degrees at night, you may be better off using a central heating system.

Space heaters can also be useful for people who share the room with a partner. If you prefer a warmer environment than your sleeping partner, a small space heater can provide heat just to one side of the bed as you’re getting ready to fall asleep.

Due to the risk of carbon monoxide poisoning from gas, propane, or kerosene space heaters, it’s better to choose electric space heaters for indoor use. The best space heaters for sleeping are convection and oil-filled space heaters, which will continue providing some heat to the room even after being turned off.

You should place your space heater about 5 or 6 feet away from you on a flat, solid, non-flammable surface. Be sure to keep the heater at least 3 feet from anything flammable, such as curtains or blankets.

Used properly, space heaters are a safe and energy-efficient way to make your bedroom more comfortable.

Is it Safe to Sleep with a Space Heater on All Night?

You may have heard horror stories about space heaters catching on fire, and it’s understandable to be wary of the potential dangers. A 2018 report by the National Fire Protection Association found that space heaters were responsible for 44% of home heating fires. However, despite their reputation, space heaters are generally safe to use as long as you follow some basic precautions.

Always leave enough space (at least 3 feet) around your space heater, and pay special attention to where you place it if you have children or pets. Never place it near water, near flammable objects like clothes or furniture, or in places where it can be easily knocked over or where something could fall on it. Keep your space heater clean and dust-free.

The safest space heaters will have features like an exterior casing that is cool to the touch, or built-in tip-over and overheat protection. These features are especially useful if you have children or pets.

No matter what safety features it has, though, a space heater should never be left on while unattended. This includes when you sleep, since you’re unable to properly monitor a space heater if you’re unconscious. Always unplug the heater when you’re not using it.

When buying a space heater, look for safety certifications from organizations like UL, ETL, CSA, or ULC. Always read the safety instructions before using your space heater for the first time, and always plug it directly into the wall – never use it with an extension cord or power bar. Be sure that the cord and the plug are in good condition.

Types of Space Heaters

Usually, space heaters for indoor use run off electricity. Within the world of electric space heaters, there are four main styles: convection, infrared, micathermic, and oil-filled.

Convection
Infrared
Micathermic
Oil-filled
Convection
Lasko 754200 Ceramic Portable Space Heater with Adjustable ThermostatConvection space heaters work by blowing air across a ceramic plate, electric coil, or another heating element. As the air heats up, the room temperature rises. Some convection heaters also have a built-in fan that circulates the hot air through the room. Convection heaters are affordable and effective in larger spaces, and the room will stay warm for a while after you turn them off. Disadvantages of convection heaters include the noise from the fan and the dry atmosphere that results from heating the air.
Infrared
GiveBest 1500W / 750W Ceramic Space HeaterInfrared space heaters send out radiant heat to any objects nearby. Compared with other models, this is the most energy-efficient space heater and it won’t dry out the air. Infrared heaters are a good choice for drafty houses or open-air environments. They are virtually silent but they will give off a luminous glow, which may make them an unsuitable choice for the bedroom. A major disadvantage of radiant heaters is that they will stop emitting warmth the second they are turned off.
Micathermic
Micathermic space heaterMicathermic space heaters get their name from the mineral, mica, that covers the heating element. Mica can withstand extremely high temperatures and when heated, it will produce both convection and radiant heat. Micathermic heaters are thin, quiet, durable, and quick to heat the room. They are suitable for use in larger spaces. The space itself should stay warm for a while even after they are turned off.
Oil-filled
Oil Filled Radiator HeaterOil-filled radiators use electricity to heat the oil inside, which then circulates through the radiator. As the radiator warms up, it distributes radiant heat to the room. Oil-filled heaters take a few minutes longer to warm up, but they provide a more consistent warmth that takes longer to dissipate. Oil-filled heaters tend to be bulkier and costlier.

What to Look For in a Good Space Heater

There are many different options to consider depending on how you plan to use your space heater. While shopping, you’ll want to take the following considerations into account.

Price
The price of a space heater will depend on the model and the quality. While you may be tempted to get the cheapest space heater, remember that a better-built, more efficient space heater will save you money in the long term. On the other hand, there’s no sense investing in a space heater that’s bigger than you need. If possible, aim for an energy-efficient space heater with eco-friendly modes.
Safety
Look for a space heater that has tip-over and overheat protection. You may also want a space heater with a cool casing to prevent burns.
Temperature Options
Most portable space heaters will have several temperature options. Convection space heaters will generally have a low setting that uses around 750W and a high setting around 1500W, with a thermostat that lets you set the exact temperature within the range you’ve selected. Look for a space heater that goes up to 1500W, enough to heat a smallish room.
Power Supply
Most extension cords are not designed to withstand the power that a space heater requires, so you should never use an extension cord with your space heater. If necessary, get a space heater that comes with a long cord so that you can plug it directly into your wall far from furniture, paper, clothes, or anything flammable. Timer
Timer
A space heater with a timer allows you to program it to turn off after a certain amount of time, helping you cut down on your bills. Although these are often marketed as “sleep timers”, we strongly recommend against leaving a space heater on while you sleep, for safety reasons.
Ease of Use and Cleaning
Some space heaters will be more portable than others – if you plan to move it from place to place, look for one with a handle. Most space heaters are simple and easy to use. Space heaters with fans are particularly prone to dust accumulation, so look for one with a dust filter and always keep your space heater clean to prevent fires.
Noise
Heaters with fans tend to make more noise, so if you’re not one of the people who use white noise to help you sleep, you might want to avoid a heater with a fan. Oil-filled heaters and infrared heaters make virtually no noise at all.
Design
Space heaters come in all shapes, sizes, and colors, so you should be able to find one that complements the aesthetic of your room. Other frills include fresh air ionizer features, handles, electronic displays, remote controls, fan-only options for summer use, the ability to oscillate, or different programming options. You might consider a small space heater so you can heat just your side of the bed.
Trial Periods, Returns, and Warranty
Warranties for space heaters usually last between 1-5 years. Depending on the heater, you may also get a short trial period.
