Space Heaters: Everything You Need to Know

types of space heaters

Space heaters are a convenient way to heat up spaces during colder months. However, with so many types of heaters on the market, it can be difficult to narrow down which one will work best for you and your needs. 

What Are Space Heaters

A space heater is a unit designed to warm a space when central heating is unavailable, too expensive, or just generally inadequate. They utilize either radiation or convection and can be powered by electricity or fuel. 

Space heaters can be handy to have in case of an emergency. For example, in February 2021 a winter storm swept through Texas causing many residents to lose power. During this time, the only way they could keep homes warm was with gas-powered space heaters. 

Types of Space Heaters

There are four main types of space heaters available, each with its own benefits and weaknesses.

1. Convection Space Heaters

Convection heaters rely on the movement of air to heat a space. This type of heating causes the warm air to rise and cold air to fall, therefore evenly heating the space. However, convection heaters are unable to heat large spaces. 

2. Radiant Space Heaters

Radiant heaters utilize radiation to heat spaces. Similar to how the sun heats the earth, these heaters will heat people and objects directly rather than the air around them. This makes them more efficient than other types of heaters. 

3. Micathermic Panel Space Heaters

Micathermic heaters utilize both convection and radiation to heat a space. The heating element heats mica stones which then emits electromagnetic rays which heat all objects in a room. This is the fastest type of heating unit because it utilizes convection and radiation. 

4. Ceramic Space Heaters

Ceramic heaters are made from plastic, metal, and ceramic in the central heating system. Ceramic is extremely durable, allowing these types of heaters to last for a very long time. There are both radiant ceramic heaters and convection ceramic heaters depending on the type of heating you would like to utilize.

What is radiant heat

Radiant heat, also known as infrared heat, warms objects and people directly rather than the air in a space. This is the same type of heat that the sun casts which is why you can remain warm even on a cold day. These heaters work by turning electrical energy into radiant heat by emitting radiation waves. When those waves hit something or someone, they release energy which in turn warms up that object. 

Why is Radiant Heat Better Than Forced Air?

Radiant heaters are ideal for a number of reasons. 

1. Energy Efficient

Radiant heaters are the most energy-efficient heaters available because they heat objects directly rather than heating an entire room. 

2. Immediate Results

Because they heat objects directly, these things and people warm up much more quickly than with a convection heater. 

3. Allergy-Friendly

Forced air heaters utilize fans to blow warm air into a room. However, this fan also kicks up dust and other particles which can negatively affect anyone with allergies. Radiant heaters don’t have fans which makes them quieter and better for those with allergies. 

Where are Radiant Heaters Most Useful

Radiant heaters can be useful in any space that needs to be warmed up. However, they become especially useful in areas such as workshops or garages that have cold concrete floors, high ceilings, and little to no insulation.

most energy efficient space heaters

Cold temperatures tend to slow down productivity and can even make active workshops less safe. Expecting your employees to work in cold temperatures can also lead to decreased employee satisfaction and rushed tasks, leaving a dent in your business. Space heaters are mobile units that can be used to heat up one room or even a workspace so you can keep employees warm and happy even in the dead of winter. 

A common complaint with space heaters is that they aren’t always exactly energy efficient. Compared to a centralized system, space heaters tend to cost more per square footage. However, there are several options for companies looking to invest in energy-efficient space heaters.

Most Energy Efficient Space Heater

Radiant space heaters are the most energy-efficient heaters on the market. Performing especially well in workshop environments where insulation may be subpar or nonexistent, radiant heaters heat objects directly rather than the air. This means you can use them in drafty, cold shops without fear of losing the heat to dissipation.

What is btu rating?

British Thermal Units (BTU) are the most common method of measuring energy. One BTU is equivalent to the amount of heat energy required to make one pound of water increase its temperature by one degree Fahrenheit. The comparable SI unit for BTUs is joules, which 1,055 joules being equal to one BTU. In terms of space heaters, BTU establishes both how much heat the heater can put out and how much energy it requires in order to provide that heat. 

Understanding BTUs will in turn help you understand how effective a heater will be in a specific space, and how expensive that heat will be in terms of energy consumption. The higher the BTU rating, the more heat energy it can provide. Units with higher BTU can heat up large spaces, or small spaces faster. 

BTUs and Efficiency

BTUs measure power, but you need a separate efficiency percentage to know how efficient a heating unit is as a whole. Calculate the efficiency percentages by dividing the hourly output BTUs by the input BTUs and then multiplying the total by 100.

what size space heater do i need?

When shopping for a space heater, it is essential to know what kind of heater and what size is best for you. Without this information, you may get one that is too small and therefore doesn’t adequately heat a space, or you may get one that is too large therefore causing you to spend more money purchasing and running it. 

What Type of Space Heater Do I Need

The first question to answer is what kind of space heater is best for you. A few options include the few we have already discussed. Here are where they are most useful:

Radiant Heaters

  • Workshops
  • Garages
  • Offices
  • Spaces with little to no insulation

Convection Heaters

  • Spaces that don't need to be warmed quickly
  • Spaces without pets or children as they can be hot to the touch
  • Bedrooms
  • Basement

Micathermic Heaters

  • Spaces without pets or children as they can be hot to the touch
  • Bathrooms
  • Bedrooms
  • Offices

Ceramic Heaters

  • Offices
  • Living Room
  • Bedrooms

How to Determine What Size Space Heater is Best

Now that you know what kind of space heater is best for you, it is time to determine what size you need. 

1. Measure the Size of the Room

To measure the size of the room, you’ll need to measure the length and width then multiply by two to get the square footage. 

2. Determine the Wattage of the Heater

A general rule of thumb is that each square foot needs 10 watts.

3. Convert Watts to BTU

British Thermal Unit (BTU) is the standard measurement used to measure energy. One watt is equivalent to 3.41 BTUs so therefore, you’ll need to multiply your needed wattage by 3.41 to determine how many BTUs you need to look for. 

4. Take Notes of Room Features

Additional features that can affect how well a room warms up includes:

  • Insulation - the less insulation, the more powerful a space heater you’ll need. 
  • Floors - cemented or tiled floors may take longer to heat up.
  • Traffic - room with more people will warm up quicker. 
  • Windows - a room fewer windows will warm up quicker and will require fewer BTUs. 

There is a lot to consider when looking to purchase a space heater. Continue reading about heater size and type of space heater >>
