How many watts does a portable heater consume?

Many homeowners view portable heaters as a blessing, feeling that they are their only possible source of warmth during the winter. However, older homes are likelier to lose heat and let cold air in through small holes or cracks. As such, some people may rely on portable heaters as their primary form of heating during this season.

If you are considering buying a portable heater, it might be tricky to determine the correct size for your home. This article will explain how portable heaters work and how they are usually used so that you can choose the best one for your home.

Another thing to consider when getting a portable heater is how much power it consumes. The smallest portable heaters created for people have a power output of roughly 250 watts.

Apart from the 100-watt layer heaters that warm chicken coops, they are the smallest accessible portable heaters. Since these heaters are meant to warm up small rooms, most people would categorize a 1500-watt portable heater as a “small portable heater.”

Can a little heater warm a large area?

The quality of the heater is an essential factor to consider when determining the appropriate wattage for a space. For example, a 250-watt portable heater should adequately warm an area between 50 and 80 square feet, while a 500-watt model is likely more suitable for spaces that measure up to 100 square feet.

The 1500-watt models, which can warm a portable up to 200 square feet, are the biggest space heaters that we can still consider “little.”

What should you use portable heaters for?

People needing a compact and efficient portable heater can find the perfect solution with the tiniest heaters. These little devices are ideal for warming up small spaces such as screened-in porches, bathrooms, and particularly chilly cubicles. Many people buy these types of heaters as they are extremely energy efficient, cost-effective, and easily fit into tight spaces. No matter what purpose you require one for, there is undoubtedly an appropriate portable heater for you.

Size of portable heater

As a general rule of thumb, a heater can heat 1 square foot for every 10 watts.

However, there are more precise measurements. How well a heater works depends on many things, like how well-insulated the room is. For example, how humid is the room, are the windows adequately sealed, and are there any spaces between the doors and frames? With all these in mind, the best approach to selecting a heater size is based on the projected square footage it can heat.

How to pick the Best portable Heater for your room

1. Know the size of your room

If you want to heat an open-plan flat, buying a single larger portable heater is often more efficient and economical than numerous small ones. When buying a space heater, think about how big the room is. This will help you choose one with enough power and coverage for the whole area. Knowing how big your room is in square feet can help you choose the right size of heating appliance for your needs.

2. Check the heater’s safety

Portable heaters have heating elements that can be hazardous to little children and pets. Also, electric portable heaters often overheat and can trip a circuit. These two factors are a major cause of concern.

Fortunately, contemporary heaters offer a variety of safety elements that reduce the possibility of dangers. Ensure the heater has an automatic shutoff and protecting plates before purchasing it. These features ensure the heater does not overheat or tip over to cause a fire. Furthermore, the protective plate will limit direct contact with the heating element.

3. Knowing the pros and cons of the different portable heaters

As was already said, there are a few distinct portable heaters, each of which operates differently and is constructed from a unique material. Therefore, you’ll need to research which best suits your needs, as they each have advantages and disadvantages.

Now, we will discuss the benefits and drawbacks of the different portable heaters.

Electric and propane-fueled heaters are the most efficient at producing warmth but pose the highest risk. In addition to fire hazards due to combustible fuels, electric heaters can cause electrical shock if improperly maintained or used correctly. 

You must monitor and regularly service your electric heaters to ensure optimum function and safety. Even if you are using propane-fueled heaters, inspect them for any signs of damage. Do not forget that improper use of propane-fueled heaters leads to carbon monoxide poisoning and many other health risks.

Ceramic and infrared heaters are beautiful and quiet but cannot heat the room as much as you want. Ceramic and infrared heaters are best for spot heating. They are not meant to be used as wide-range heaters.

Commonly asked question

Can two portable heaters be used in one area? 

Technically, you could do this, but we strongly advise against it. Utilizing multiple portable heaters will drastically increase the risk of potential accidents and, therefore, should be avoided. It is important to remember that space heaters contain heating elements, making them hazardous if not cautiously operated. This is especially pertinent if you have young children or pets in your home, as they may need help understanding the risks associated with their usage. Instead of getting two tiny heaters, buying a large portable heater is better.

How many watts does a big heater use?

The largest portable home heaters can consume up to 4,000 to 5,000 watts. These heaters are the best choice for heating big rooms since they can effectively warm 500 square feet or more. Furthermore, these devices provide enough warmth to make your home comfortable. 

May I get a portable heater if I already have central heating?

Of course, yes. Many people use portable heaters to supplement their home’s heating system. Older houses often have gaps and cracks between the windows and doors, which allow heat to escape, making some areas of the house chillier than you would want. A space heater placed in these locations can make a significant difference.

In conclusion

Always use your room’s size to guide the type of heater you will get. Bigger rooms require larger portable heaters. It is important to note that the bigger the electric heater, the more warmth it produces and the more electricity it consumes. 

Secondly, always check the safety feature of the heater to reduce the risk of fires. It is better to buy a heater from trusted producers.
