Bathroom radiator Kermi B20-R 1511 x 540 mm, white, 525 W

The Kermi B20-R bathroom radiator is a vertical panel radiator designed for use on central heating systems. With dimensions of 1511 x 540 mm and a rated heat output of 525 W, this white radiator is intended to provide efficient space heating in bathrooms and utility areas where a compact, upright format is required. The B20-R model features a slim profile that fits narrow wall spaces while delivering a predictable thermal output for planning and installation.

Advantages

The radiator’s vertical design saves horizontal wall space and allows placement beside doors, windows, or between fittings. Its stated 525 W heat output supports straightforward load calculations when sizing the heating system for a bathroom or utility room. Finished in white for a neutral appearance, the radiator integrates with common bathroom decor and is compatible with standard central heating pipe connections. The panel construction provides even surface temperatures and reliable convective heat distribution.

Suitable for

• Heating bathrooms and washrooms in residential properties
• Providing supplementary heat in utility rooms and laundry spaces
• Installations where vertical radiators are preferred due to limited horizontal wall space

Key specifications

• Height: 1511 mm
• Width: 540 mm
• Rated heat output: 525 W (for use in central heating systems)
• Orientation: vertical panel radiator
• Finish: white
• Mounting: wall-mounted installation

How to use

Mount the radiator on a suitable load-bearing wall using appropriate brackets and fixings for the wall material. Connect the inlet and outlet to the central heating circuit following local plumbing codes and the radiator manufacturer’s installation instructions. Bleed air from the radiator after filling the system to ensure full heat output. Adjust the room thermostat and any local radiator valve to achieve the desired ambient temperature.

Usage recommendations

When planning installation, verify the radiator’s heat output against the room’s calculated heat loss to ensure sufficient capacity. Use corrosion-inhibiting additives if recommended for the heating system, and service valves and connections periodically to maintain performance.
