Convector vs Radiator: Which One to Choose?

Convector vs Radiator: What to Choose for Winter Warmth and Summer Comfort

Modern heating and cooling systems face ever-higher expectations. Users want efficiency, low operating costs, fast temperature response, smart control, and of course – aesthetic appeal. That’s why classic radiators and modern convectors offer complementary solutions, not competition. The key is choosing the right unit for your space and specific needs.

What's the Difference Between a Radiator and a Convector?

The core difference lies in the heating principle.

• Radiators (such as the RADIK VKM8) heat the room using a combination of radiant heat and natural convection. They warm both the air and surrounding surfaces (walls, furniture), creating a pleasant and balanced thermal comfort.
  
  
• Convectors work solely through air circulation. Thanks to their low water content, they heat up – and cool down – very quickly, making them perfect for dynamic temperature control.

Advantages of Radiators

Radiators are a proven solution with a long service life and high design potential. Models like RADIK PLAN VKM8 feature a flat front panel and minimalist aesthetic. Looking for a true design statement? Go for the RADIK PREMIUM or the KORATHERM VERTIKAL – perfect for narrow wall spaces.

Radiators also provide a gentle radiant warmth, which is especially welcome during long winter evenings. They're ideal for spaces where stable, consistent comfort is needed – like bedrooms and children’s rooms.

Advantages of Convectors

Convectors bring a modern approach to heating and even allow moderate cooling. This is useful in summer months when you don’t need air conditioning, just a few degrees cooler for comfort.

A great example is the KORAFLEX Optimal-V FVO, equipped with fans that allow rapid performance adjustment based on actual needs. Or the KORALINE bench convector, which combines a heating unit with seating – a clever solution for entryways or conservatories.

With their low water volume, convectors require less energy and react more quickly – ideal for buildings with low-temperature heat sources such as heat pumps or solar systems.

Where Should Each Type Be Used?

Performance Meets Design

Whether you opt for a radiator or a convector, there’s no need to compromise between performance and style. All KORADO products are designed to match your interior while delivering high comfort and efficiency.

Most radiators and convectors are also compatible with smart home systems (BMS), helping to maximize energy efficiency.

There’s no one-size-fits-all answer. Radiators and convectors each have unique strengths:

• Radiators excel in spaces where steady, radiant comfort and visual design are key.
• Convectors shine where fast reaction, cooling capability, or low-temperature operation is required.
