Best Space Heater Reviews & Guide For 2021

Space heaters, not to be confused with propane heaters, ever, are handy devices that help assist in keeping portions of a home or office warm in winters. There are small, countertop space heaters that can aid in taking the chill off of the bathroom in the morning, space heaters that can add comfort to a small bedroom, and larger space heaters that will help add a few degrees of heat to a larger room. Knowing the environment you wish to heat is one of the pillars of choosing the best space heater for you.

There are also different types of heaters in terms of how they generate the heat. Some make you feel warm like the sun is shining on your body. Other space heaters blow warm air on you with a fan. Other space heaters are in a radiator style that heat oil and have the warmth radiate through the room. There are also some newer types of space heaters coming on the market that are in a panel form.

The best space heater really depends upon where you want the heating to go and upon your budget. Space heaters can range in price from around $20 to $500. The most common space heaters with high reviews tend to run in the $20 to $100 range.

This article will look at the very best space heaters in a variety of types.


How to Choose the Type of Space Heater You Need

If you have places in your home or office that are cold and uncomfortable, you need the best space heater for your particular situation. Examples of places that may need a space heater include:

  • In the office, where the main heating system fails to warm your cubicle
  • A chilly bathroom
  • In a bedroom with no vents or registers
  • In a living room, where the heating system struggles to keep the room warm

Another great use for space heaters is to turn down the central heating and have the space heater, or a few space heaters, in different rooms. This may save on heating costs, but it is dependent upon the wattage used by the space heater and the costs of electricity where you live. Electricity costs vary by state.


Types of Space Heaters

There are several types of space heaters. The difference is in how the heat is generated and how it is emitted. One of the ways in which people can best choose the right space heater to solve their particular heating issue is to understand the best uses for each type of heater. One important issue about space heaters is that no space heater will replace one’s home heating system. Space heaters just don’t generate enough power for that because the vast majority of space heaters on the market are electric. Their maximum wattage output is 1,500.

The different types of space heaters on the market are:

Convection Heaters

These either have a ceramic plate or an electric coil and have a fan to send the warmth generated by the heater out into the room or space to be heated. Most of the modern convection heaters today use a ceramic plate.

The pros of convection heaters are that the air blows on you as soon as you turn them on, so they supply instant warmth. They are usually small or medium-sized. The small models are designed to sit on a countertop. The medium-sized models are designed to sit in the middle of a room. They are great for heating a small bathroom or small bedroom. The cons of convection heaters are that their fans may be a bit noisy, and the air they blow may not be uniformly warm. Many are undersized to warm a larger room, but there are notable exceptions.

Infrared Heaters

These heaters warm like the sun. Electricity is passed over wires. The wires radiate their heat out to the objects surrounding the heater. Convection heaters warm the air, which may dry it out. Infrared heaters heat the objects in the room. Smaller infrared heaters have a parabolic dish or are in a small, metal box. They can heat a person in an office cubicle or a small area in a room.

The larger infrared heaters use quartz tubes, often come in an attractive wooden box and can heat larger rooms. The pro is their warm, uniform heat that will not dry out the air. The con is that one has to take care about what is in the room near the heater in order to not start a fire.

Oil-filled Heaters

These often are in the shape of a radiator, with fins. The heaters are filled with an oil that the heater maintains at a certain temperature. Oil-filled heaters are one of the safest types of space heaters, since the oil that is being heated is contained in the steel radiator. They send a uniform warmth out into a room and smell pleasant as they heat. They are capable of warming medium- to large-sized rooms.

Pros are their safety, the amount of heat they generate and the uniformity of the heat. The only con may be their size. They are the largest form of space heater but often have wheels to move around the room.

Micathermic Heaters

These are somewhat newer on the market. They radiate and emit warmth by convection, so there is both heat that radiates from them and warm air blown out of them. They work by mica sheets being warmed by electricity. They are flat panels and can often be mounted on wheels or to a wall. They are more frequently used to heat medium- to large-sized rooms. Pros are that these units are quiet, space saving and heat up more quickly than oil-filled heaters. The major con is that micathermic heaters are limited in their coverage. They will heat a room up to around 150 square feet.


Features of Space Heaters

Some of the common features of space heaters include:

Thermostats – Many space heaters have thermostats that allow one to maintain the area at a certain temperature. The most reliable space heater thermostats tend to be those that use a simple rotary dial. Digital thermostats that one can set to a specific temperature may not be reliable or can malfunction.

If you want a digital thermostat to add to your space heater, and it does not come with one, Amazon sells the popular Lux Win100 Programmable Outlet thermostat. It will turn your space heater on and off in order to maintain a desired temperature.

Timers – Some space heaters have timers that turn the unit on and off at a desired time.

Automatic Shut-Off – Many space heaters on the market today come equipped with automatic shut-off systems. These shut the heater off in the event the unit tips over.


Best Usage Practices

The main advice for space heaters is to use them safely. They need to be placed away from clothing, curtains or anything that they could get so hot as to ignite. Some space heaters may not be placed on a carpeted floor, while others have a pedestal that allows for safe use on any type of flooring. It is also important to not allow the cord to be in the path of the heat output, so it does not melt or catch on fire.
