Buying Guide For The Best Space Heater for a Large Room
Just like an air conditioner is a necessary home accessory in summers, you will find yourself needing a similarly powerful space heater when the surrounding temperature drops below a certain level in winter. While a lot of air conditioners these days offer all-year performance with a built-in space heater, sometimes the warmth created by these units is simply not enough to offer a relaxing living environment. Therefore, a lot of users prefer to get a dedicated space heater, especially for larger rolls like their living room or dining room.
So, we have prepared this list of the best space heater to help you find the best space heater for your needs from the lots of options available out there. But in order to find the perfect unit, one has to consider a lot of factors and check if they suffice one’s requirements or not. Even though we have mentioned all of the best features of every space heater on this list, you might get confused between a few properties. To clear your mind, we are including this buying guide for the best space heater for a large room. We can assure you that you can see the perfect option for your needs right on this list once you go through our buying guide.
Power Capacity
Before you start considering a space heater for your home or office, you should first check its power rating and see if it is the best option in terms of power capacity in your budget or not. This factor can offer you a good idea about the overall performance of the unit according to its power consumption. Generally, the space heater which has a higher power capacity offers a higher temperature difference between the maintained temperature and ambient temperature of the room.
Therefore, it is ideal to pick up the most powerful option you can find in your budget. But with that being said, you should also think about the fact that high-powered options also consume more power to operate and can be expensive in the long term in terms of the running costs. So, choosing an overly powerful unit for a smaller or medium-sized room can be a bad idea. Right now, the most popular options in the market offer a power rating ranging from 1000 watts to 2000 watts, and some even higher than that. Within that, the ones with 1500 watts power rating offer desirable performance for a large room.
Coverage Area
Speaking of large rooms, you should also consider checking out the suitable coverage area of the space heater you are buying to double-check its compatibility with your room. Since a lot of manufacturers mentioned the possible coverage area of the space heater in the specification list, it becomes really easy to pick an option that is suitable for a certain room. All you will have to do is compare this coverage area with your room and make sure that it is equal to, or greater than the actual square footage area of your room.
And since the coverage area is also mentioned in the square feet unit, it becomes even easier to compare the two. If you end up with a space heater having a lesser coverage area than the carpet area of your room, it might fail to generate enough warmth in the room and make each maintain the air temperature in each and every corner of the room. On the other hand, if the coverage area is too much, it will consume more power than needed, increasing your monthly energy costs. But in the latter case, you can adjust the heating mode of the unit and use it at a lower setting to get the perfect output.
Heating Modes and Control Options
In a lot of cases, using the space heater is pretty simple since most new-generation devices offer simplified control options, making the space heater easily accessible for everyone. Unlike before when using a space heater used to be very difficult, nowadays, you will find only a couple of knobs or buttons on the unit provided to select the heating mode and intensity of the performance. As for the heating modes, it is preferable to buy a space heater that comes with a variety of heating modes so that your space heater will be a viable option in all weather conditions.
And with more control options like speed control, you can adjust the overall performance of the space heater as per your needs. It is also beneficial if the space heater arrives with a remote. With that, you can change certain settings of the space heater such as output temperature or speed without having to move from your couch. Some smart options also have WiFi connectivity along with support for a dedicated mobile app. With that, you will get even better access to the machine and regular updates from the manufacturer for additional features. Most smart space heaters offer automated performance by scheduling or via a built-in ambient temperature sensor. Other smart control options include direct voice access provided with the help of AI voice assistants like Google Home or Alexa.
Reliability
While going through our list, you might have noticed that most space heaters designed for large rooms are heavy on the pocket. And if you want the best value for your investment, you must select an option that ensures proper working conditions and performance for years to come. For that, you have to consider the reliability factor of a space heater. Unlike various performance features and specifications, checking the reliability is a bit of a complicated matter. For that, you will have to check the brand that is offering the space heater and check its review and feedback from existing users.
This will give you an idea about the quality of the exterior as well as interior components powering the space heater. A simpler way to check the reliability of a certain space heater is by checking the warranty period allotted by the brand for the given product. If the brand is offering a long warranty period, it means that the brand has a lot of trust in the build quality of the unit. If something goes wrong within the warranty period, you will be able to claim free-of-cost repairing services from the brand, and even replacements in worst-case scenarios. Therefore, it is important to check the warranty period of the space heater before you make a choice.

- Infrared heaters: These heaters work by emitting infrared radiation, which is absorbed by surfaces and objects in the room.
- Ceramic heaters: These heaters use a heating element made of ceramic to produce heat.
- Oil-filled heaters: These heaters use oil as a heat-transfer medium and have radiators that heat up and release heat into the room.
- Fan heaters: These heaters use a heating element and a fan to circulate warm air throughout the room.
- Micathermic heaters: These heaters use a combination of convection and radiant heating to warm a room.
- Portable heaters: These heaters are designed to be easily moved from one location to another and can be powered by electricity, propane, or kerosene.
