Looking to get to the heart of things? “What is a radiant heater” is a question worth explaining. Simply put, radiant heat is warmth that radiates from a central source – think a compact wall-mounted heater, like Comfort Cove – to directly heat the space around it. By installing radiant heaters in your home, you can efficiently warm up rooms from the walls, floors, or ceiling, without wasting energy on circulating hot air.
How Do Radiant Heaters Compare to Traditional Forced-air Heating Systems in Energy Efficiency?
When it comes to heating your home, there are pros and cons to each system. Radiant heaters and traditional forced-air systems have their own unique advantages and disadvantages when it comes to energy efficiency.
What are Radiant Heaters?
Radiant heaters use electric heat to warm objects and people, rather than heating the air. This type of heating system is commonly used in areas with mild winters or for spot heating a specific area.
How Many Watts Do Radiant Heaters Use?
Radiant heaters generally use between 60-150 watts of electricity, depending on the size and type of heater. For example, a small personal heater might use 60 watts, while a large heater for a living room could use 150 watts.
Traditional Forced-Air Heating Systems
Forced-air systems, on the other hand, use ductwork to distribute heated air throughout your home. These systems are more common in colder climates and are often used to heat entire homes.
How Many Watts Do Traditional Forced-Air Heating Systems Use?
Forced-air systems can use significantly more electricity than radiant heaters. A small forced-air system might use 1,000-1,500 watts, while a larger system could use 3,000-6,000 watts or more.
Energy Efficiency Comparison
In terms of energy efficiency, radiant heaters tend to be more efficient than traditional forced-air systems. This is because they don’t heat air that is lost through vents and ductwork, which can account for up to 30% of the energy used by forced-air systems.

How Does the Type of Radiant Heater (electric, Hydronic, or Infrared) Impact Its Efficiency and Performance?
When it comes to choosing a radiant heater, understanding the differences between electric, hydronic, and infrared types is crucial for optimal performance and efficiency. Each type has its unique characteristics, pros, and cons that affect how well it warms a space.
Electric Radiant Heaters
Electric radiant heaters use electrical resistance to generate heat. They are often the most affordable option and can be a good choice for small to medium-sized areas. Electric heaters usually have a single-point heat source, which can lead to uneven heating.
- Pros: Inexpensive, easy to install, and quiet operation
- Cons: Limited coverage area, single-point heat source can lead to cold spots
Hydronic Radiant Heaters
Hydronic radiant heaters use hot water circulated through pipes to heat a space. They tend to be more efficient than electric heaters due to their ability to distribute heat more evenly. Hydronic systems require a central boiler and piping infrastructure, making installation more complex and expensive.
- Pros: Even heat distribution, energy-efficient, and can be integrated with cooling systems
- Cons: Higher upfront cost, complex installation, and potential leak risks
Infrared Radiant Heaters
Infrared radiant heaters use infrared radiation to warm objects and people, rather than heating the air. They are often used to provide supplemental heat and can be more energy-efficient than traditional space heaters. Infrared heaters do not dry out the air, making them a good option for spaces with high humidity.
- Pros: Energy-efficient, dry air retention, and supplemental heat provision
- Cons: Limited coverage area, can be uncomfortable if not properly sized
How Do Radiant Heaters Affect Indoor Air Quality and Humidity Levels?
Radiant heaters release heat through radiation, rather than convection, which means they don’t blow hot air around like traditional space heaters. This could initially seem like a good thing, but it can also lead to stagnant air with minimal circulation.
- Air Quality: Radiant heaters can emit particles and chemicals into the air, particularly if they’re not properly maintained. Inhaling these particles can exacerbate respiratory issues, so it’s essential to clean and inspect your radiant heater regularly.
- Humidity: Radiant heaters can also affect indoor humidity levels. Since they warm objects and people rather than the air, they don’t really address humidity issues. This can lead to dry air, which can cause discomfort and even health problems.
To mitigate these effects, consider combining your radiant heater with a humidifier or air purifier. These accessories can help maintain a healthy indoor environment by controlling humidity and air quality. Additionally, make sure to follow the manufacturer’s instructions for cleaning and maintenance to minimize the risks associated with radiant heater use.
How Does a Radiant Heater Transfer Heat Directly to a Room’s Space?
Radiant heaters, also known as infrared heaters, work by emitting heat directly into the surrounding space. This process is different from traditional heaters, which heat the air and then circulate it throughout the room.
How It Works
- The radiant heater contains a heating element, usually a metal filament or ceramic emitter, that is powered by electricity.
- When turned on, the heating element heats up, emitting infrared radiation in the form of long waves.
- These infrared waves travel through the air and are absorbed by objects and surfaces in the room, including people, walls, and furniture.
- The absorbed heat energy is then transferred to these objects, warming them up.
- As the objects warm up, they, in turn, radiate heat back into the air, creating a natural convection process.
Heat Transfer Process
- Direct Heat Transfer : The radiant heater emits heat directly into the space, warming objects and people in the direct path.
- Conductive Heat Transfer : The heater’s warm surfaces may also conduct heat to other objects and surfaces through direct contact.
- Convection Heat Transfer : As objects warm up, they radiate heat back into the air, which circulates and redistributes the heat throughout the room.
