Long description

Product Description

The Thermwell black flat panel mirrored vertical radiator provides warmth, contemporary styling and a practical full length mirror within one space saving design. The matt black panels sit evenly on either side of the central mirror, creating a distinctive feature suitable for both modern and traditional interiors.

With a height of 1800mm, this vertical radiator uses unused wall height rather than occupying valuable horizontal space. It works particularly well in hallways, bedrooms, bathrooms, kitchens, extensions and living rooms where wall space may be limited.

Two widths are available. The narrower 417mm model features four front panels positioned around the mirror, while the wider 553mm model features six. Both widths can be selected with single or double panel construction. Single panel radiators provide a slimmer installation, while double panel models offer increased heat output for larger or cooler rooms.

The radiator is manufactured from 1.6mm premium mild steel and protected by a durable triple layered finish. It has standard 1/2 inch connections and is designed to connect to a conventional UK central heating system.

Wall mounting brackets and fixings are included. Radiator valves must be purchased separately, allowing you to select straight or angled valves to suit your pipework.

Heat output requirements vary according to the size, insulation and construction of the room. Always check the required BTU output before ordering and ask a qualified heating engineer if you are uncertain.

Radiator Buying Guide (Content Section)

Choosing the Right Radiator Size

Selecting the correct radiator size helps ensure your room heats efficiently and comfortably. The heat output of a radiator is measured in BTU (British Thermal Units) or Watts, which indicate how much heat the radiator can produce.

Smaller rooms such as cloakrooms or en-suites typically require lower heat output, while larger bathrooms and living spaces may require a radiator with a higher BTU rating.

When choosing a radiator, consider:

• Room size – larger rooms require higher heat output

• Ceiling height – higher ceilings may require additional heating capacity

• Insulation levels – well insulated rooms retain heat more effectively

• Window size – rooms with large windows may lose heat more quickly

For best results, choose a radiator with sufficient BTU output to comfortably heat the space.

Radiator Installation

Most modern radiators connect directly to your home's central heating system using standard 1/2" inlet and outlet connections. Installation is similar to fitting a standard household radiator.

Radiators are typically supplied with wall mounting brackets and fixings, while radiator valves are purchased separately to allow you to choose the style and control type that best suits your installation.

For safety and correct operation, radiators should always be installed following manufacturer guidelines.

Radiator Valves

Radiator valves control the flow of hot water entering the radiator and help regulate the room temperature.

Common valve options include:

• Manual valves – simple temperature adjustment

• Thermostatic valves (TRV) – automatically regulate room temperature

• Angled or straight valves – depending on pipe position

Choosing the correct valve type ensures the radiator operates efficiently within your heating system.
