Infrared supplementary heating can provide extra warmth at a seat or workstation. Start with a specific comfort need alongside existing heating: where is it too cool, when do you use that spot and what should the addition do? Adding a panel does not automatically save energy; it may mean extra electricity use.
This guide assesses supplementary heating by operation, placement, controls and actual use. It helps you choose for your home or business location and customer projects. We help end users, installation companies and wholesalers with product data and a suitable combination of panel and controls.
Key points
Define the existing heating’s role. Choose an occupied zone, check heat transfer to it and follow mounting instructions. Calculate costs using actual kWh and your own tariffs. Avoid general savings percentages, fixed watts per square metre and guarantees of a lower main thermostat setting.
When is infrared supplementary heating suitable?
Supplementary heating adds heat alongside an existing system. Primary heating must cover the structural heat demand of the room or home. A panel making a desk comfortable is not automatically suitable for maintaining the whole room’s temperature. First describe the function you expect.
Targeted heat can be relevant where one fixed spot needs more comfort than the rest of the room. Whether this costs less depends on heating actually reduced elsewhere and electricity added. A lower background temperature also requires attention to the rest of the building, moisture and comfort. Do not omit ventilation to retain heat.
Assessing technology, comfort and consumption separately
An infrared panel uses electricity to warm a surface. That surface releases energy as thermal radiation and also convection. People and surfaces absorbing radiation become warmer. The eventual sensation depends on panel, distance, direction, furnishings and room conditions. The technology does not make insulation, ventilation or suitable controls unnecessary.
Radiant fraction, surface emissivity and electrical conversion efficiency are different concepts. Electric resistance heating converts almost all input electricity to heat, but does not automatically make infrared cheaper than other electric appliances or a heat pump. A radiator also releases both radiant and convective heat.
Energy consumption depends on input power and time actually operating. At constant full power: watts × hours ÷ 1,000 = kWh. A 500-watt appliance running continuously at full power for two hours uses about 1 kWh.
A thermostat can switch the appliance off intermittently. Occupancy time and on-time therefore differ. Multiply measured kWh by your electricity tariff for a cost indication. Lower nominal power does not guarantee lower total consumption if the appliance must operate longer to meet the same heat demand.
No fixed warm-up time or temperature reduction applies to all panels. Assess comfort at the actual seat or workstation. The technology does not replace ventilation or cleaning or offer general health or lifespan guarantees. Natural air movement and dust movement remain possible without a fan.
Applications in different rooms
In a living room, assess a fixed seating area. In a kitchen, wall cupboards, equipment and table position matter. In both cases, mounting and radiation direction must suit the occupied zone. Above a sofa, table or kitchen island is not automatically suitable: follow the manual and assess obstacles and clearances.
For office or home working, consider posture and occupancy duration. Desk heating needs a purpose-designed product; an ordinary wall panel is not automatically suitable under a desktop. For several workstations, occupancy, zoning and individual controls form part of the design. Match controls to occupancy and assess total workstation consumption.
A plug-in thermostat is only usable where panel, plug connection, load and location are suitable. Use a qualified installer for fixed connections or unclear wiring. In a bathroom, panel, controls and connection position must meet applicable installation requirements and manufacturer instructions. An IP rating alone is not a complete placement assessment.
Preparing installation and required output
Record room dimensions, insulation, windows, ventilation, operating times and desired seating or working zone. Have panel output and placement assessed together. There is no universal wattage per square metre or fixed distance suitable for every supplementary-heating project. A high ceiling or long distance may require a different solution, not arbitrary extra watts.
Check clearances, load-bearing capacity, electrical connection and environmental suitability in the manual. Furniture can limit direct radiant heat transfer to the occupied spot. Seek expert assessment of mounting and connections if uncertain.
Check panel model, supply voltage, output, permitted switching load and specified control method. Compare total connected output with thermostat, receiver and installation limits. A volt-free contact, switched mains voltage and a manufacturer-specific connection are not simply interchangeable. If unsure, have us and the installer assess the combination.
Check that controls and appliance suit one another and what functions actually exist. Schedules, presence sensors, adaptive warm-up and open-window detection may help but differ by model. Detection thresholds and switching loads are product-specific. An app or energy-management link does not guarantee savings; incorrect settings may increase consumption.
Our proposal for infrared supplementary heating
We supply private and business end users, installation companies and wholesalers. Describe the room, existing heating, desired heating zone and operating times. State dimensions, insulation details and preference for wall, ceiling or another version. We help compare suitable products, installation conditions and controls.
Choose according to your use
Compare measurements at similar operating duration, outdoor temperature and settings. The main meter also includes other appliances. Where appropriate, use a suitable energy meter or reliable appliance measurement function. Consider accuracy and any changes to existing heating; one isolated meter reading does not prove savings.
Do not compare only purchase prices and wattages. Include controls, installation, maintenance, energy prices and the whole heating arrangement. Electric supplementary heating is not automatically cheaper than gas or a heat pump. Results depend on the systems and heat demand actually replaced or added.
Frequently asked questions about infrared supplementary heating
Is infrared always the lowest-consumption supplementary heating?
No. Compare application, heat demand, placement and controls. A solution for one workstation needs different assessment from a system maintaining a whole room’s temperature.
Is a panel safe to touch?
An operating panel can become hot and touching may cause injury. Follow mounting and clearance requirements and consider children, pets and other vulnerable users. A temperature limiter does not eliminate the risk. Do not cover the appliance unless expressly permitted by the manufacturer.
