How to Pick the Perfect Space Heater for Your Needs?

Aside from the Dr. Infrared Heater DR-968H, there are other top-quality space heaters available to choose from. Since there are so many options on the market, here’s everything you need to know to pick the right one for your needs.


Do you need a heater that can warm and dehumidify?

Knowing what you’d like to achieve by installing a space heater will help you select one with the features to satisfy your needs.

Physical Size

If a space heater is too small, it may not be powerful enough to provide the level of heating you want. But if it’s too big, you might have trouble finding a space for it in your room. Also, a larger space heater will be heavy, making it harder to move around.

Be sure to go for a space heater that conveniently fits into the space you have in mind and won’t be too large to move around or store when you don’t need it.

Safety Features

Space heaters can get pretty hot. If left running for long periods, some are at the risk of overheating. To prevent burn injuries or a fire accident, go with a space heater with safety features, like automatic shutoff that kicks in when the machine overheats or tips over.

Another essential safety feature is a Heat Protective Casing that prevents the body of the space heater from getting too hot. This is especially essential if you have kids or pets in the house that may carelessly get too close to the heater.

Temperature Controls

Do you want a heater that you can simply set to high or low temps? Or, a heater that lets you choose precise temperatures?

Go for a heater that you can adjust to suit your needs. But make sure that the controls are easy to understand and user-friendly. The more control you have over the level of heating a space heater provides, the better you can enjoy it.


The best space heater for a large room will have features that make moving it around a breeze. The said feature may be a handle for carrying or wheels for easy movement. If you know you are going to be moving your space heater around a lot, especially if it’s a large one, make sure it has portability features.

Easy Installation

Electric heaters are super easy to set up. Simply pull it out of the box, plug it, and you are good to go. On the other hand, if you opt for a gas space heater, you may have to purchase specific components and tools for hooking it up to a gas line.

Extra Features

Do you want a simple space heater or one with additional features for your comfort?

The best space heater for a large room will come with a remote control that lets you adjust it from a distance. Other options come with a timer that you can set, and a thermostat that lets you monitor the temperature in a room.

Some options can also double as a dehumidifier.

Noise Level

If you want a heater that’s as quiet as possible, it’s best to go for one that doesn’t use a fan. A good alternative is a radiative heater since it has fewer moving parts.


You don’t want a heater that works great but is an eyesore in your living space. Electric space heaters come in various shapes and designs, and some are very attractive. There are even some like the Duraflame 3D that simulate the appearance of a blazing fireplace.

Consider the heater’s aesthetics instead of focusing solely on its performance, to get a heater that matches the décor of your home.


More expensive heaters are typically more powerful and have more features. The cheapest models are often less durable and less reliable heaters.

If you are on a budget, instead of going for the most expensive or cheapest option, go for one that offers all the features you need. It should deliver such features to your satisfaction at a price that doesn’t exceed your budget.
