What Are the Disadvantages of Infrared Heating Panels?

Published in Infrared Heating Disadvantages 4 mins read

Infrared heating panels, while often praised for their efficiency and modern aesthetic, come with several disadvantages that potential users should consider, including specific health considerations and practical installation limitations.

Potential Health Concerns

A significant area of concern for some individuals regarding infrared panels relates to potential health risks, primarily due to their method of heat generation through radiation.

  • Types of Infrared Radiation: Infrared radiation is broadly categorized into two main types:
    • Near Infrared (NIR): The heat from near infrared can be intense and penetrating. This intensity can make it unsafe, particularly with prolonged or close exposure, as it can penetrate deeper into the skin.
    • Far Infrared (FIR): Most domestic infrared heating panels utilize far infrared, which is generally considered safe. This is the same type of gentle, radiant heat emitted naturally by the human body and the sun.
  • Public Perception vs. Reality: Despite the safety of far infrared used in home heating, the general association with "radiation" can lead to questions and apprehension regarding the technology's safety. It's crucial for consumers to understand the distinction between near and far infrared to address misconceptions.

Higher Upfront Cost

One of the most notable disadvantages of infrared heating panels is their higher initial purchase and installation cost when compared to conventional heating systems, such as traditional convection heaters or standard central heating radiators.

  • Initial Investment: While often lauded for lower running costs over time, the upfront investment required for purchasing the panels and their installation can be a significant barrier for some homeowners.
  • Return on Investment: The long-term savings on energy bills may take several years to offset the higher initial expenditure, depending on usage patterns and electricity tariffs.

Heating Method Differences and Limitations

Unlike traditional convection heaters that warm the air in a room, infrared panels primarily heat objects and surfaces directly. This difference can lead to several perceived disadvantages:

  • Perceived Temperature: The ambient air temperature in a room with infrared heating may not feel as uniformly warm as with a convection system. Users might experience the radiant warmth on their skin and objects but notice the air itself is cooler, which can be an adjustment.
  • Line of Sight Requirement: For optimal effectiveness, infrared panels require an unobstructed line of sight between the panel and the objects or people intended to be heated.
    • Cold Spots: Obstacles like large furniture, tall plants, or even people can block the infrared rays, creating "cold spots" or areas that do not receive direct heat.
    • Strategic Placement: This necessitates careful and strategic placement of panels, which might limit interior design flexibility. For example, placing a large sofa directly in front of a wall-mounted panel would significantly reduce its heating efficacy for the rest of the room.
  • Lack of Air Circulation: While beneficial for those with allergies (as it doesn't circulate dust), the absence of warm, moving air might feel less "cozy" or traditional to some users accustomed to conventional heating.

Dependency on Building Insulation

While infrared panels are efficient at directly heating surfaces, their overall energy efficiency and effectiveness are significantly impacted by the quality of a property's insulation.

  • Heat Loss: If a property has inadequate insulation, the warmth radiated to walls, floors, and objects can quickly dissipate, requiring the panels to operate longer to maintain comfort.
  • Reduced Effectiveness: In poorly insulated spaces, the perceived benefits of infrared heating, such as targeted warmth and efficiency, may be diminished, leading to higher-than-expected running costs and reduced comfort.
  • Solution: To maximize the performance and energy savings of infrared heating, investing in robust building insulation is crucial.

Aesthetic and Placement Challenges

Although infrared panels are generally sleek and minimalist, their effective placement can pose challenges:

  • Specific Mounting: They must be mounted on walls or ceilings in positions that allow their heat rays to cover the desired area without being blocked. This can sometimes conflict with existing room layouts or preferred furniture arrangements.
  • Number of Panels: Larger rooms or rooms with complex layouts may require multiple panels to ensure even heat distribution, increasing both the visual presence of the panels and the overall installation cost.
