Table of Contents


When it comes to keeping your home or office warm during the colder months, choosing the right heater can make all the difference. There are many options available, but two popular choices are unit heaters and room heaters. In this ultimate guide, we will discuss the differences between these two types of heaters and help you determine which one is right for you.

What are Unit Heaters?

Unit heaters, also known as space heaters, are designed to provide heat to a specific area or room. They are commonly used in commercial and industrial settings, but can also be used in homes. These heaters are typically installed on walls, ceilings, or under windows, and are often powered by electricity or natural gas.

Advantages of Unit Heaters:

  • Efficient heating for large spaces
  • Can be ducted to provide heat to multiple rooms
  • Easy installation

Disadvantages of Unit Heaters:

  • May not provide even heating throughout the room
  • Can be noisy
  • Requires professional installation

What are Room Heaters?

Room heaters, as the name suggests, are designed to heat a single room or small area. They are portable and can be placed anywhere in the room where heating is needed. Room heaters are typically powered by electricity or gas, and come in a variety of sizes and styles, including radiant, convection, and fan-forced heaters.

Advantages of Room Heaters:

  • Portable and can be moved from room to room
  • Provide quick and localized heating
  • Easy installation

Disadvantages of Room Heaters:

  • May not be as efficient for heating larger spaces
  • Can be a fire hazard if not used properly
  • Limited heat output

Which Type of Heater is Right for You?

Choosing between a unit heater and a room heater depends on various factors, including the size of the space you need to heat, your heating needs, and your budget. Here are some considerations to help you make the right decision:

  1. Size of the Space: If you need to heat a large area, such as a warehouse or a garage, a unit heater is usually the better option. Unit heaters are designed to provide efficient heating for larger spaces and can be ducted to distribute heat evenly throughout multiple rooms. If you only need to heat a single room or a small area, a room heater will suffice.
  2. Heating Needs: Consider how often and for how long you will need to use the heater. If you need continuous and powerful heating, such as in a commercial or industrial setting, a unit heater is more suitable. However, if you only need occasional or temporary heating, a room heater would be a more cost-effective option.
  3. Budget: Unit heaters are generally more expensive to purchase and install compared to room heaters. Consider your budget and determine how much you are willing to spend on a heater before making a decision.


  1. Can I use a unit heater in my home?
  2. Yes, unit heaters can be installed in homes. However, they are more commonly used in commercial and industrial settings due to their ability to efficiently heat large spaces.
  3. Can I move a unit heater from room to room?
  4. No, unit heaters are typically installed in a fixed location, such as on a wall or ceiling. They are not portable like room heaters.
  5. Can a room heater be used to heat a large space?
  6. While room heaters can provide localized heating in a small area, they are not designed to efficiently heat large spaces. If you need to heat a large area, it is recommended to use a unit heater.
  7. Are unit heaters energy-efficient?
  8. The energy efficiency of unit heaters can vary depending on the model and type of fuel used. It is important to choose an energy-efficient unit heater and ensure proper installation and maintenance to maximize efficiency.
  9. Do room heaters require professional installation?
  10. Most room heaters are designed for easy installation and can be done by the homeowner. However, it is always recommended to read the manufacturer’s instructions and follow safety guidelines to ensure proper installation.

Unit heaters are ideal for heating large spaces and provide even heat distribution, while room heaters are more suitable for smaller areas and provide localized heating. Consider the size of the space, your heating needs, and your budget when making a decision. Don’t forget to read the manufacturer’s instructions and follow safety guidelines for proper installation and use of your chosen heater.
