Radiant heating for conservatories and sunrooms

Enjoy year-round thermal comfort without condensation or overheating

Conservatories and sunrooms are transitional spaces between indoors and outdoors. Bright and pleasant to live in, they can quickly become too cold in winter or difficult to heat effectively with traditional systems. Electric radiant heating offers an efficient, invisible, and silent solution perfectly suited to these glazed spaces.

Why choose radiant heating for a conservatory?

Unlike convection heaters that circulate air and often cause condensation on glass, radiant heaters warm people and surfaces directly. They don’t circulate warm air but emit gentle heat by radiation, making them ideal for:

• Effective heating without causing misting or humidity
• Maintaining a comfortable temperature even in highly glazed structures
• Preserving the aesthetics of the space with slim, discreet models
• Providing instant comfort without waiting for warm-up

Which type of infrared for conservatories?

For conservatories, medium or long-wave devices (IR-M or IR-C) are preferred as they provide gentle warmth suitable for prolonged use and compatible with glazed structures.

Avoid short-wave infrared heaters (IR-A), better suited for very open or windy areas.

Recommended power and installation

Power depends on the size and insulation of the conservatory:

• 8 to 12 m²: 2,000 to 2,400 W
• 12 to 20 m²: 2,800 to 3,600 W
• Above 20 m²: possibility to install two heaters facing each other

Installation tips:

• Fix heaters at a height of 2.0 to 2.5 metres
• Direct radiation towards occupied zones (seating, table, loungers)
• Use ceiling or wall mounts depending on configuration
• Choose an IP rating suitable for moisture-prone conservatories (minimum IP24)

Recommended products examples

• HEATSTRIP® Elegance: ultra-thin design, perfectly integrated into conservatory ceilings
• HEATSCOPE® Vision: gentle heat, invisible light, ideal for prolonged use
• Models with thermostat or remote control: to adjust temperature by time of day

Old vs modern conservatories: key differences

Older conservatories are often poorly insulated and require higher power or more direct heating. Modern aluminium double-glazed conservatories allow efficient use of gentle infrared radiation.

Heating can also be automated using smart home boxes or intelligent regulation systems based on time or outdoor temperature.
