How To Choose The Most Appropriate Space Heater For Your Requirements?

After going through some of the top space heaters available, we’ll go deeper into the differences between the various heating systems and the features to look for.

Space heaters are available in a variety of designs.

As you may have noticed from the reviews above, heating technology comes in a variety of varieties. You’ll need to understand how they function before you can choose between them.

Heaters That Emit Infrared Light

Infrared heaters generate infrared radiation that is focused in a certain direction. When the radiation comes into touch with an item, it warms it. This implies that infrared heaters are best utilized for direct or spot heating, which requires directing them at a specific target.

These kinds of heaters are frequently utilized in commercial and industrial environments, as well as garages. While the heat quickly dissipates after the heater is switched off, infrared heaters are more energy efficient since they expel 100% of the heat they generate with little to no heat loss during the transmission.

Oil-filled heaters

Oil-filled heaters resemble standard water-filled radiators and operate on a similar principle. Internal oil reservoirs are heated in an oxygen-free container to prevent them from igniting. The heated oil then radiates heat into the room via the metal.

Once the oil is heated, it maintains its temperature for a lengthy period of time. This implies that oil-filled heaters do not need to be continuously on to generate heat. Oil-filled heaters equipped with a thermostat utilize electricity just to heat the oil initially and then cut off when the oil reaches a preset temperature, making them extremely efficient.

The disadvantage of oil-filled heaters is that they do not efficiently project heat, making them more suitable for smaller spaces.

Ceramic Heaters

Ceramic heaters operate by delivering an electrical current through a ceramic heating element that is capable of reaching extremely high temperatures. The ceramic element’s heat is subsequently spread around the room via a fan.

Ceramic heaters account for the great majority of space heaters due to their ease of use, rapid heat-up time, and energy efficiency.

Convection Heaters

Convection heaters work by pulling air from under the device. The air then flows through a heating element and returns to the room as warmed air via the unit’s top.

In comparison to radiated heat, such as that produced by a ceramic or oil-filled radiator, convection heaters distribute heat more uniformly and remove less moisture from the air. However, they frequently heat a space more slowly than other types of heaters.

How To Use Your Space Heater Safely And Efficiently?

While many space heaters are quite energy-efficient and hence environmentally beneficial, there are a few more actions you can take to maximise their efficiency:

Turn Down Central Heating Before Use

If you’re utilizing a space heater to provide targeted heat in a specific area, turn down your central heating system prior to using it. Not only will it be inefficient to have two heating systems running in the same space, but it will also be difficult to maintain a consistent temperature.

Heat Only One Room At A Time, When A Boost Is Needed

One of the most efficient ways to utilize a space heater is to place it in a room that you anticipate remaining in for an extended length of time and then switch off your central heating. This may be a garage, man cave, recreation space, or home office.

Heating a single room is always more efficient than heating a whole house. Radiant heaters, particularly oil-filled heaters, do not require a constant operation to provide heat, making them even more efficient.

Use Your Space Heater At A Low Temperature

The overwhelming majority of space heaters will have a low-temperature setting, often about 750 watts. This setting is more than sufficient to immediately produce heat in a modest room. Maintaining this lower setting on your space heater improves your energy use.

Choose A Model With Safety And Efficiency Features

As is the case with any type of heating system, you’ll want to prefer units equipped with modern safety measures. These include tip-over sensors that prevent the unit from tipping over and thermal cutouts that prevent the device from overheating.

Numerous versions will also have energy-efficient features. Eco-modes, intelligent thermostats, and active temperature controls are a few examples. These methods minimize the amount of heat and energy lost by the unity, so increasing its efficiency and hence its environmental friendliness.

Certain WiFi-connected gadgets also enable you to monitor the energy use and output of your heater. This data enables you to optimize when and how you use your heater.

FAQ

To ensure you have all of the necessary knowledge, we’ve compiled answers to some of the most often asked questions concerning space heaters and their efficiency.

What Is The Most Efficient Type Of Space Heater?

Regrettably, there is no simple solution to this issue. The efficiency of a heater varies between models and is dependent on the conditions in which it is utilized. All electric heaters are regarded to be 100 percent efficient, as they convert all of the power they consume to heat.

Additional energy-saving features, such as eco-modes, can help make a heater more efficient. Although oil-filled radiators have the lowest cost per kilowatt-hour on our list, this is only one factor.

Ultimately, all heaters will be more efficient if they are operated properly, as mentioned above.

Are Space Heaters Safe?

Any heating method has a degree of danger. However, space heaters provide significantly fewer dangers than any open flame. By utilizing a space heater appropriately, the danger associated with it can be mitigated:

  • Maintain a minimum distance of three feet between your heater and combustible things such as drapes, furniture, or bedding.
  • Avoid placing your heater on top of furniture or concealing it in any way.
  • Keep an eye out for high-traffic areas and always position your power wire in such a manner that it cannot be easily tripped over or knocked free.
  • As is the case with all electrical equipment, avoid allowing your space heater to come into contact with water and avoid touching an electric heater when wet.
  • Avoid leaving your space heater unattended for extended periods of time or leaving it on while you sleep.
  • Always disconnect a space heater after using it.

Where Should I Put My Space Heater?

Space heaters are most effective for heating a limited area. The majority of the heaters on our list are intended for use in spaces of between 100 and 200 square feet. You’ll get the most out of your space heater if you avoid attempting to heat a large area with it.

When it comes to a precise location, keep your heater at least three feet away from combustible things and away from anything you don’t want to fade over time.

  • Radiant heaters may be installed in any location in a room.
  • Convection heaters require more air circulation to operate well.
  • Infrared heaters must be directed directly towards the object being heated, including oneself.

Is It OK To Leave A Space Heater On All Night?

Generally, no. You should never leave any type of heater alone. If, on the other hand, a space heater is your main source of heat in really cold weather, you may decrease the danger slightly by purchasing a model equipped with a thermal cutoff, tilt sensor, and programmable timer.

The thermal cutoff and tilt sensor keep you safe, while the programmable timer allows you to design your heater to turn on and off at intervals rather than continually.

Do Space Heaters Use A Lot Of Electricity?

A 1500-watt space heater consumes around $100 in power per month if it is used for eight hours each day. As a result, they are an extremely energy-intensive solution to operate continually. It is worth noting, however, that space heater are not intended to be permanent heating systems.

They are most effective when used in brief bursts to heat smaller rooms rather than when used to heat a whole house via central heating. In these instances, a space heater is a more cost-effective option.

The Best Energy-efficient Space Heater

A space heater is a great and energy-efficient way to warm a place that lacks heating or that requires less warmth than a whole house.

We love the Dyson AM09 for its variety of functions, remarkable energy efficiency, and high build quality. However, we’ve included a number of additional solutions that may be more appropriate for your particular situation.
