Types of Space Heaters

Best heaters for large can be categorized into different types based on the different methods they use to heat rooms. Types in this context include convection space heaters, radiative heaters, oil-filled space heaters. Also, these devices are categorized based on the power they use, including electric and gas space heaters.

  • Convection heaters: You can use this type if you desire some extra heat in a well-insulated room. Most commonly, convection space heaters are electric and have an inner metal or ceramic heater construction plus an effective fan for warmth distribution in a room. In addition, this type might consume more electricity but has the advantage of instant heat coziness.
  • Radiative Heaters: The radiative type gives off heat through an infrared spectrum like a halogen light bulb. Essentially, this type of heaters warm objects within a room rather than heating air. Unfortunately, these heaters don't look as attractive as their convective counterparts, even with effective heat dispersion.
  • Oil-filled space heaters: This type tends to provide both radiant and convection heating and is more energy-efficient. Fundamentally, these heaters are powered by electricity, which heats the diathermic oil in the heater for retaining heat for long. Subsequently, the air within a living room is slowly heated even after the heater is turned off.
  • Electric Space Heaters: This type uses electricity by simply plugging your machine into an electrical outlet. They are the most common heating power options and are ideal for the contemporary home.
  • Gas Space Heaters: These heaters use propane gas or butane gas. This power method has the potential of emitting dangerous fumes such as carbon monoxide and carbon dioxide. They are therefore not ideal for closed or poorly ventilated rooms. However, in outside living spaces like back porches, these heaters have more heating capacity than the electric heaters.

Why Do You Need a Space Heater for a Large Room?

  • A space heater is portable. Devices in this category are deliberately designed for easy movement for heating different parts of living spaces. Some of the features that enable portability include handles and wheels.
  • Energy efficiency. A modern large room heater can be deemed to be more energy efficient than the traditional heating variants. Some models are built with the eco-mode feature to ensure the utility of least energy while heating effectively. In addition, a modern space heater is built to consume energy when necessary, such that it goes off when the set temperature is achieved.
  • Quick heating. A space heater might appear proportionally smaller than large drafty rooms, but it's capable of heating spaces quickly. Unlike the traditional approach of lighting firewood, modern heaters only require turn-on buttons from the power outlet to the heating device. Also, through the infrared mechanism, heated objects ensure heat spreads faster within a room.
  • Safety. You can safely use a portable space heater in a large room without burning people and pets. Accordingly, a modern heating system is built with a cool-to-touch exterior for insulation during and after the heating process. This means that no one gets burned when they accidentally touch a working heater.

Factors to Consider Before Buying the Best Space Heater for Large Drafty Room

1. Power

Heat emission by room space heaters definitely relies on a power source. Subsequently, the power aspect also determines the cost efficiency and price of your select heater for large room spaces. The more efficient a large space heater is on power and costs, the more expensive it will be.

In light of this understanding, most heaters for large rooms are electric, measuring power in watts. On functionality, watts determine the warmth a heater can provide and at what cost. For electric heaters, the most efficient should warm a large space quickly and automatically go off to save on electricity consumption. Accordingly, the best space heaters in the electric category can consume about 1,500 watts which can be adequate for full warming of a 300 square foot room and up to 1,000 square feet in the presence of a central heating system.

Fortunately, contemporary heaters for large rooms are built for energy saving, unlike their traditional counterparts. Specifically, the infrared heaters are built for quick heating and effective heating for large spaces. However, even as the modern type of space heater is built for efficiency, you should also compare the consumption of your heater for large rooms with the local power rates. You can also use multiple heat settings to adjust the temperature depending on your room's size and prevailing heat needs.

There are also other power options for products in this category, like propane and kerosene. However, these options for a large room space heater are not ideal for closed spaces due to the emission of carbon monoxide.

2. Portability

Heating a whole large room can take more time than a specific spot. Luckily, there are portable heaters for large rooms. Portability can come in the form of a lightweight size or wheels for easy movement. Consequently, a large room space heater, whether small or large, can be moved to a specific room section where heat is needed more and urgently.

Moreover, you should consider the power cord length for easy portability, depending on the plug-in point. We have included the power cord feature under portability because most space heaters for large rooms are electric.

3. Space Efficiency

Besides portability, you should also consider the footprint of a heater for large rooms, whether on the floor or wall-mounted. Even in the scope of drafty rooms, you wouldn't want a heater that congests or takes up much of your living room. In the category of space heaters for large rooms, oil-filled heaters occupy the most space. Conversely, wall-mounted heaters are the most space-efficient but with the downside of non-portability.

Pairing space efficiency with portability, an electric heater still fits these user requirements. Additionally, the best heaters for large spaces are built with an enhanced radius for better room heating. Eventually, even with a space-efficient room heater, it should effectively fill warmth in a large room.

4. Even-Heat Spread

Furthermore, the best space heater for large drafty room spaces should effectively warm all room corners evenly. This requirement means that a room heater should be equipped with a system for even distribution of hot air. Understandably, convective heaters have an even heating capacity through a fan that distributes warm air. Some distribution fans oscillate while others rotate from side to side for even warmth distribution in drafty rooms.

5. Automatic Shut Down

Any preferred heater for large room spaces should have an automated shutdown feature when a room is adequately warm or when it topples over. There are three automatic shutdown features that can be included in a timer, thermostat, and tip-over protection. Despite these in-built shutdown features, you shouldn't leave a heater on for long or overtime to avoid fire hazards.

In the case of a timer, it turns off a heater when a set or programmed time elapses. The timer feature is especially resourceful to avoid forgetting you left your heater running. Subsequently, it is easy to find a heater with an in-built timer, plus different timer settings across different manufacturers.

You can choose a heater with a thermostat. Fortunately, most of the quality devices in this category come with thermostats to measure an environment's temperatures and go off in case of overheating. Moreover, you can get a device with an adjustable thermostat that you can program to turn off when a room reaches its intended warmth. Generally, digital thermostats are easier and precise to use than dial alternatives.

There is also the option of devices with tip-over safety. This feature works by turning off a heater when it falls to prevent fire risks. Ideally, the best space heaters shouldn't lack the tip-over safety feature, especially if you have kids and pets at home.

6. Safety Features

Apart from the auto-turn-off feature, you should also ensure an all-around safe heating device. First, always ensure you read a user manual for maximum application safety. Even before you pay for a selected heater, it should have gone through safety tests. Safety lab labels such as CSA (Canadian Standards Association), Underwriters Laboratory (UL), and ETL (Intertek) are good safety indicators.

Additionally, a heater should have a cool-touch exterior to prevent the outer part from getting hot. A cool-touch exterior is especially an important safety feature for protecting users, pets, and items from burns when heating is in progress.

Also, in gas and propane heaters, you should get one with an automatic shut-off feature when there isn't oxygen for combustion, which is a sign of high carbon monoxide levels. Furthermore, you also ensure that a gas or propane heating device comes or is fitted with a combustion venting system.

7. Low Noise

Noise might sound miscellaneous, but it is an important aspect to consider for non-distractive operations. For example, a heating device would score low if it warms your space effectively but at the disadvantage of noisy operation. Subsequently, you can opt for an oil-filled radiator or infrared space heater for reduced noise levels and white fan noise.

8. Remote Control

After all the above considerations are in place, it can also be rewarding to have a remote-controlled heater. More so, if all you want to do is switch it on and off, it would save you the energy of getting up from your comfy couch. The remote control also features the advantage of adjusting temperature settings and changing between work modes effortlessly.
