Understanding Space Heaters And Safety Precautions

Space heaters are becoming increasingly popular as an efficient way to supplement home heating systems. However, they can sometimes be dangerous and cause injuries or property damage if not used appropriately. Before using a space heater, it’s essential to understand its basic components and features to minimize the risk of accidents.

Types Of Space Heaters And Their Wattage

Space heaters come in various shapes and sizes, making it difficult to choose the right one for your needs. Some of the typical types of space heaters include:

  • Propane heaters: They use propane gas as fuel and are ideal for heating large spaces. Their wattage can range between 4,000 to 18,000 w.
  • Electric heaters: They are the most common type of space heaters and come in various sizes. Their wattage can range between 200 – 1500 w.
  • Infrared heaters: They emit infrared radiation that heats up objects rather than air. Their wattage ranges between 300 – 1500 w.
  • Ceramic heaters: They are similar to electric heaters and use an electronic heating element instead. Their wattage ranges between 200 – 1500 w.
  • Oil-filled radiators: They use oil to generate heat and are ideal for long-term use. Their wattage can range between 600 to 1500 w.

When choosing a space heater, make sure to check its wattage and compare it with your power outlet. Overloading your power outlet can cause electrical fires, and in extreme cases, lead to the destruction of your property.

  • Radiant heaters: These heaters emit infrared radiation directly onto objects and people, which warms them up. They are ideal for small spaces, but they can be pricey and can be a fire hazard.
  • Convection heaters: These heaters use a heating element to warm the air, which then rises and circulates the room. They are ideal for large spaces, but they take a while to heat up.
  • Fan-forced heaters: These heaters use a fan to blow air through a heating element, which warms the air and circulates it throughout the room. They are quick to heat up, but they can be noisy.
  • Oil-filled heaters: These heaters use electricity to heat oil that is sealed inside the unit. The oil then heats up and radiates heat throughout the room. They are quiet and energy-efficient, but they take a while to heat up.
