Best Space Heater For Large Room Buying Guide

There are a few knowledge you need to have before purchasing a space heater; one is the larger the room, the larger the space heater you may want to get, but it goes beyond that! We want you to make a perfect choice, not only based on your fixed budget, but we feel the product you get should be the correct fit for the task you want it to carry out.

So we would give you a buying guide, as we discuss the space heaters considering the heater type, the heating capacity, energy efficiency, safety features, and noise level.

Heater Type

Space heaters have two main types, and the kind of heater you are getting is an important factor to be considered when getting one for large rooms. The two types of space heaters we would base on are the convection space kind and the radioactive kind.

Usually, most of the convection space heaters are small, portable and can effortlessly be moved. They make use of a heating element to warm the air, and circulates it heat itself or use an inbuilt fan to move the air around large rooms. Convection space heats up faster in smaller rooms since most of them are fan-based, you only need to turn it on, and it begins to work. When other heaters warm the air, the surface temperature from the oil-based convection heater stays much lower to heat rooms faster.

On the other hand, radiative heaters are bigger than fan-based heaters for larger rooms, but they are not so attractive. They work like halogen light bulbs to emit heat in the infrared spectrum. So instead of heating the air in the room, it warms the objects around it. They are more efficient for smaller rooms than the convection space heaters since they heat up longer and do not cool down so fast.

Heating Capacity

Heat capacity would be the required amount of heat needed to raise the temperature of the room and create warmth. Most space heaters are powered on 1500 watts, some others with a dual setting option can produce lower heat at 750 watts.

The heating capacity is a crucial factor to consider. Ideally, 1500 watt is appropriate for a 150 square feet room. Now that we have already established that the wattage of the space heater determines the heating capacity, you may want to consider the British thermal Unit measurement and temperature rise of the device. One watt approximately equals 3.14 BUTs.

It would be an unwise decision to get a heater that would not warm your room up as much as you want. A factor that would determine the heating capacity of the space heater you are planning to get is the type; another is the size.

Even though most space heaters would perform well in small places, there are secrets behind using them used to address the heating conditions in larger rooms too, one of them is the larger the room, the larger the space heaters and the other could be the way you use them.

Energy Efficiency

It is one thing for your space heater to produce sufficient heat to warm up your room, it is another important thing for the heater to effectively manage the energy used, which in turn saves up on your energy bill. Space heaters can warm a particular room and reduce the power spent on central heating of the whole house.

Some heaters would be sufficient enough to provide the required heat you need to warm up your room without weighing so much on your energy, and there are others that consume so much power.

Some features like the auto shut off timer exist to manage the energy properly. You can set a specific schedule when you want your heater to automatically work or stop working and save up on energy bills. Some space heaters allow you to set up the timer within a range of 1 to 7 hours, while some others allow setting up to 12 hours.

For an economical way to effectively heat your room, you should get a space heater that is good enough to perform it’s duty and lightens the weight on your energy. The space heater should also have a timer system, so when you put it on and set up the timer, you can be sure that your bills are not pilling up.

Safety Features

Of course, electrical devices come with some kinds of risk, and that means the space heater is not an exception. Manufacturers of space heaters equip these devices with safety features to prevent the risk of fire or overheating.

Some of the features are the tip over sensor, and thermal shut off that becomes active when the device gets hotter than it should be. The safe to touch feature also seem reasonable to mention, since the external body of most heaters do not hurt your hands even when you are running the device at maximum use for hours.

Noise Level

heating devices

Even when large rooms in your home need some space heaters, it may be upsetting to when you always have to hear the sounds from the blowers. For light sleepers especially, you may find it difficult to enjoy your sleep with the constant whining sound of the heater.

Fan equipped heaters are usually noisy than the fanless unit since the heater noise comes from the oscillating sound the fan in it. The fanless heaters exhibit silent operation. Most modern portable heaters are fan based, and they make loud noises, even though some may be louder than the other. You can check through the decibel rating listed in the product specification to compare, and know that the higher the rating, the louder the heater.

So if you have a problem with the noise level of a heater, you should instead go for a fanless radiator. But if you buy a fan equipped heater, you could get one with a lower sound.

Which is the best room heater to buy?

Space heaters are not designed to be the primary source of heat, and they also work well to compliment your heating scheme in the rooms or certain spaces. The Dr. Infrared Heater is our choice for the best room heater since it excels amidst other space heaters with a dual technology that propagates heat faster and stabilizes it, so there are no hot and cold spots.

The electronic thermostat has a high range of 50 degrees to 86 degrees. Like several other space heaters, Dr. Infrared Heater also has features like thermostats, timers, thermal switch to shut off the device during overheating and also tip over sensors to help you concentrate the heat to a specific room of your choice.

Frequently Asked Questions

Is room heater good for health?

While a room heater operates, whether it is a fan equipped convection heater or halogen room heater, it burns up the oxygen and drops the humidity level in the air. When the oxygen level falls beyond the limits, it may lead to suffocation especially if you or any member of your household is asthmatic. The solution to this could be for you to open the door a little for natural air to come in.

Asides from oxygen, the reduced humidity in the air leads to dry eyes and nasal blockage which you can work out with a humidifier, or you can put a bucket of water in the corner of the room. If you use an oil based filter to dampen the air a little, you can prevent the oxygen and humidity levels from dropping so much.

Rest is good for the health, but you may have issues with the unwanted noises of the heaters as it is quite annoying to bare while you are sleeping. We suggest you drink enough fluid to avoid dehydration and water good wool cloth, so you reduce your dependency on room heaters alone.

Is room heater safe?

The main potential risk you can have while using a heater is fire accidents. Most times when fire accidents occur it is due to leaving the device unattended. While using your space heaters, you need to avoid covering the room heater outlet, so your device does not catch fire instantly. You should also put away your polyester clothes or inflammable items when you use radioactive heaters.

Not all space heaters are safe to touch; some are very hot, so you should make sure you keep kids and your pets away from them. We suggest you also consider a heater that both time based and tip over sensor features for assured safety so that automatically switch off either when during overheating or after your set duration.

Which room heater is best halogen or fan?

Deciding on which room heater is the best between halogen and fan would depend on your preference and the purpose of their use, as they both have advantages and disadvantages.

Rather than heating the air in the room like the fan based heater, halogen room heaters work by heating the objects directly around it. In some ways, like their size and how they handle large rooms better, they could be preferred. They also have silent sounds cool down slowly, so you can enjoy a quiet, warm room even after the device is turned off.

Some advantages of the fan based heater are that it heats up and distributes warm air in the room faster than other types of heaters, to ensure there are no cold or hot spots. They also have small and portable sizes and can fit perfectly into smaller rooms. The Fan equipped heaters always have a better and stylish build up in case you prefer not to tamper with your home decorations. The downsides you may have to deal with is the noise level and the fact that it cools down faster than you may expect.

Which room heater is safe for baby?

Either walking or crawling, babies are always curious, and it would not matter how much you watch them, they are drawn to shiny and bright items. Some coil heaters could be attractive to them and cause severe burns, that is the reason why you should get a wall mounted heaters or heaters that are safe to touch.

Another specification you should consider when deciding on a heater for your babies are the ones with thermostat control to turn it off and on automatically. Most importantly, the best heaters to get at this stage are oil heaters or radiators to reduce cases of dryness or itching on your baby’s skin.

Oil filter heaters help protect humidity and oxygen levels from burning low; they also come with features like timers and thermostats. Oil filters are the best choice for child safety, but monitoring that operation is still essential for utmost safety.

How to calculate room heater size?

Estimating the room heater size would depend on several factors, but there is one fundamental concept that guides it, and it is 10 watt per square foot of space. Comparing the heater’s watt with the room size according to this precept is quickest and easiest way to calculate room heater size, but other conditions may flaw this method, like the room insulation.

The heavily insulated room would require lesser power to heat it. Instead of 10 watts, approximately 7.5 watts would do the job, while lightly insulated rooms may need up to 12 watts. Places without insulation like garages or basements would let heat out as it gets in. Other conditions are the ceiling heights, outside temperatures, windows and the amount of supplemental heating.

Which room heater consume less electricity?

Even with your need for instant heat, you would still prefer to use an energy efficient room heater. The room heaters are meant to supplement the heat source for individual rooms, and it would be unwise when they take so much energy and add to the electrical bill.

Generally, oil filled radiator and halogen heaters consume lesser energy since they do not have to power the oscillating blower of the fan based room heater. When getting a room heater, you should look for one that is accurately effective enough for your target room, so you do not have to end up opening up your doors and windows from too much heat.
