How to choose the best space heater

Are you searching for the best space heaters but are confused because of so many styles and kinds available? We’re here to help you find the right space heater according to your requirements. We have compiled a short buying guide that will help you make an informed decision. Following are some factors to consider before buying a space heater:

Heater type

The first thing that you should consider before buying a space heater is to determine the type that you need. There are many types of heaters but there are three basic heating technologies used in them. The electric space heaters can be divided into these categories: radiant, convection, and fan-forced. The radiant heaters allow warmth to be generated, dispersed and used and it provides quick heating in small spaces. The convection heaters provide even heating throughout the room and the fan-forced heaters dissipate the heat around the room very efficiently.

Apart from the electric heaters, there are propane space heaters, diesel space heaters, and paraffin space heaters. There are heaters that can be mounted on the wall and some can be just kept on the floor. Selecting the right type of heater will make sure you get enough and proper warmth that you want.

Heating capacity

If you need a portable heater, you must consider its size before buying. The size of the heater will determine its heating capacity, that is, the area it will cover. The heating capacity of a space heater can be known by the wattage rating. As a general rule of thumb, a room heater will use 10 watts of heating power to heat one square foot of your space. So, if you’re going to buy a 1500 Watt heater, it will easily cover an area of 150 square feet. However, these estimations are not fixed to every type of space heater, there can be some variations too. There are other factors too such as the indoor environment, heating technology, and others.

Safety features

Another important thing to look for is the safety features of the space heater. There should be enough of them on the device so that it operates safely in your indoor environment. One important safety feature is the overheat protection which makes sure that the device doesn’t get too hot and switches it off automatically. This safety feature makes sure that the internal heating elements of the space heater don’t get too heated up and prevents any form of electrical circuit damage. This not only keeps the heater safe but the surrounding environment too.

The tip-over protection is another safety feature that makes sure that there is no risk of fire if the heater accidentally falls down or is tipped over. However, it is important to take care yourself and keep any children or pets away from the heater so that it isn’t knocked down or tipped over. Space heaters should be safe enough so that it doesn’t create a fire hazard or burn anyone. Also, inspect carefully the space heater’s cords for damage and never use an extension cord with an electric heater.

Energy efficiency

If you are concerned about rising energy costs and utility bills, you must consider the efficiency of the space heater. There are EER ratings that are present on space heaters and that can determine their energy efficiency. Choosing an energy efficient space heater is imperative if you want to keep your electric bills in a reasonable range. Also, there are energy efficient features such as the energy saving modes, low wattage, adjustable thermostats, and programmable timers that help to stop the skyrocketing electric bills.

Noise level

Some space heaters produce more sound than others during the operation. Non-fan forced units such as oil-filled radiator or base board heaters are good if you don’t like noise. If you want to place heater in your office or bedroom, the noise of the heater can disturb you, so it is important to check this feature.

Electric space heaters

Electric space heaters are compact and lightweight and can be easily placed in your home or office.
