Radiator VIESSMANN VK/K Type 22 H900 x W1600, double-panel convector, central heating

VIESSMANN VK/K Type 22 H900 x W1600 is a double-panel convector radiator designed for central heating systems. The Type 22 construction with two panels and two convector fins increases surface area for heat transfer, providing stable and even room warming. The radiator dimensions — 900 mm height and 1600 mm width — make it suitable for medium to large rooms in residential or commercial settings. It connects to standard hot-water central heating installations and is intended for fixed wall mounting using compatible brackets.

Advantages

The double-panel, double-convector design improves thermal output without significantly increasing depth, delivering efficient performance for its footprint. Steel panel construction ensures durable operation and consistent heat distribution. The radiator is compatible with conventional hot-water systems and offers a straightforward installation profile for standard plumbing connections.

Suitable for

• Residential living rooms, bedrooms and hallways requiring medium to high heat output
• Office spaces and small commercial rooms where even heating is needed
• Replacement or upgrade of existing panel radiators in central heating systems
• Rooms with wall space that can accommodate a 1600 mm wide radiator

When it may not be suitable

This radiator may not be appropriate for very small rooms where a large width would dominate the space or where lower heat output is sufficient. It is not suitable for installations that require low-profile or floor-mounted convectors, or for systems incompatible with standard water-based central heating.

Key specifications

• Type: Double-panel, double-convector (Type 22)
• Height: 900 mm
• Width: 1600 mm
• Material: Steel panel construction with convector fins
• Connection: Standard hot-water central heating connections (side or bottom depending on chosen valve configuration)
• Mounting: Wall-mounted with compatible brackets

How to use

Mount the radiator on a suitable load-bearing wall using brackets sized for the radiator height and weight, ensuring horizontal alignment. Connect to the central heating system using appropriate valves and pipe fittings; bleed the radiator after filling the system to remove trapped air. Set the heating system controls and thermostatic valves as required to achieve the desired room temperature. Regularly check for leaks and purge air periodically to maintain efficient operation.

What to consider before purchase

• Available wall length and clearances for a 1600 mm wide radiator
• Compatibility with existing central heating valves and pipework
• Required heat output for the room based on size, insulation and heat losses
• Mounting surface strength and suitable bracket type for a 900 mm high unit

Usage recommendations

For optimal performance, size the radiator according to room heat loss calculations and install thermostatic radiator valves to control room temperature efficiently. Ensure periodic bleeding and maintenance of the central heating system to preserve heat output and prolong service life.
