Safety tips for the proper use of a space heater

Using a space heater can be dangerous if you don’t know when, where, and how to use it. Here are some tips for safe use.

– You can leave your space heater on for long periods of time unattended, including while you sleep. Also, make sure that one of the major recognized organizations accredits your product. It should also have certain features, such as automatic shut-off, tip-over protection, shut-off timer, and adjustable thermostat.

– Follow a few basic safety rules. For example, make sure you have a working smoke detector and keep flammable objects away from the heater.

– Turn off your heater when you are not in the room. This is certainly the easiest way to prevent a fire hazard. When it is not lit, it does not use energy and does not risk igniting anything nearby.

– Avoid using a space heater as much as possible while you sleep. Indeed, it is difficult to realize what is happening in the room when you sleep. If you plan to leave it running for part of the night, make sure it is equipped with some fully functioning safety features.

– If you need more heat in a specific room, use space heaters sparingly. Using electric space heaters to heat the whole house is extremely expensive. In theory, electricity costs less than gas or oil, but electric heaters are very energy-intensive, and therefore more expensive.

– Do not use your space heater to dry your clothes. You risk causing a fire. By placing clothing on your radiator, you risk blocking the ventilation holes and causing the device to overheat.

The different types of heating

Convection heating

Convection heaters have a unique design and tend to warm the air in a room rather than the people in it. They produce warm (lighter) air that gently rises to the ceiling. The cold air, which is located high up, will exchange places with the warm air and be heated in turn. 

A convection heater can take the form of baseboard heaters or heaters filled with water or oil. The most efficient devices are those that run on water and oil.

Radiant heating

Heaters that use radiation are more useful for warming bodies and objects in a room rather than the air. These heaters quickly provide heat to anyone nearby. 

This type of heating is preferred if you need to heat a room quickly. However, you should be aware that radiant heaters can pose certain risks. If placed too close to flammable objects, they can burn people and animals. The risk of fire is therefore greater.

Radiant panel heating

Radiant panels are a relatively new concept that is rapidly gaining popularity. The radiant panel heater can be fixed to the wall or placed on the floor with its support. By allowing warm air to radiate from the appliance, radiant panel heaters work in the same way as oil heaters.

Electric heating

Electric heaters use a wire that runs through pipes to heat water. The latter is heated by the passage of an electric current. The current is then converted into heat which circulates in the radiator. For every unit of energy used, electric heaters produce one unit of heat.

Gas heating

Combustion heaters are the other type of auxiliary heater. These units are available in both vented and unvented versions, but gas heating is not used indoors. They heat a space with flammable fuels like kerosene, propane, or natural gas.

Use of an unvented unit indoors is not recommended. Many states have banned the use of kerosene heaters indoors. Indeed, this type of heating can cause the appearance of harmful by-products, such as carbon monoxide.

What to Consider Before Buying the Best Heater

Before buying a space heater, you should consider the following points:

The type of heating desired

The type of heating is the most important criterion to take into account before buying a space heater. Although there are many different types of heaters, electric heaters fall into three categories: radiant, convection, or forced air.

Radiant heaters provide rapid, targeted warming in tight spaces. Forced air heaters have an internal fan that blows air over a heating element. Thermal mica heaters, on the other hand, quickly provide heat throughout the room, while saving space.

Heating power

Another factor to take into account when buying a space heater is its power. In other words, the area that the heater will be able to heat. The power, expressed in watts, determines the surface that can be heated. On average, a space heater requires 10 watts of power per square foot. 

When used as a supplemental heat source, a typical 1500 watt heater can cover an average-sized room of around 150 square feet. However, this is indicative data and does not apply to all models. Some portable heaters can cover larger areas depending on the heating technology used, the climate, and its use.

Energy consumption

If you are concerned about your energy consumption and do not wish to increase your heating budget, it is necessary to evaluate the energy consumption of auxiliary heating. Unlike air conditioners, there is no rule for measuring the energy consumption of auxiliary heaters. 

That said, the cost of running heaters is easy to determine using a simple formula. Choose a heater that won’t use too much water, taking into account the climate in your area and the area you want to heat. This will prevent you from seeing your electricity bills increase too considerably.

Safety devices

Portable heaters can quickly become fire hazards if not used properly. Therefore, security is an essential point to consider.

Many manufacturers equip their electric heaters with cool-touch surfaces and other safety features for safe operation and to reduce the risk of fire. Some models are equipped with an internal switch that instantly shuts off the heater if it inadvertently turns over.

Most space heaters are also equipped with an overheating protection device. This is essential for safe use. In practice, a switch automatically turns off the heating when the internal components reach a temperature threshold that is too high.

The sound level

Many portable heaters, like most electrical products, emit some noise when in use. That said, some models are louder than others. For quiet use in quiet places like your bedroom or workplace, opt for fanless appliances, such as a baseboard heater or oil-filled radiator.

Cadet baseboard heaters, for example, are ideal for heating an entire room with minimal noise. Radiant heaters are great for bedrooms and offices because they are quiet.

Is a space heater really efficient for heating a small space?

Yes, that’s quite true. But are they sure? This varies by product. To verify that your space heater is safe to use inside your home, make sure it has certifications from a recognized organization.

If you’re careful and place your heater strategically, you’ll never feel cold again, at least not in your bedroom.
