Mirror Radiators

Frequently Asked Questions About Mirror Radiators

What is a mirror radiator and how does it work?

A mirror radiator is a central heating radiator with a full-length mirrored surface built into its design, combining two functions in a single wall-mounted unit. It connects to your existing central heating system in the same way as a standard radiator and heats the room through the same convection process, with the mirror surface sitting flush to the front of the unit.

Are mirror radiators suitable for a bathroom?

Yes, mirror radiators are one of the most practical choices for bathrooms because they provide both heating and a full-length mirror without occupying any additional wall space, which makes them particularly well suited to smaller bathrooms where every inch counts. It is important to confirm that the model you choose meets the IP rating requirements for the specific zone it will be installed in, which your installer will be able to advise on before fitting.

Will a mirror radiator make a small room look bigger?

Yes, the reflective surface of a mirror radiator bounces light around the room, which creates a sense of depth and makes smaller spaces feel larger and brighter than they are. Positioning the radiator on a wall opposite a window maximises this effect by reflecting natural light directly back into the room.

How do I know what size mirror radiator I need?

The correct size is determined by the BTU (British Thermal Unit) requirement of your room, calculated using its dimensions, ceiling height, glazing, insulation, and orientation. Use our BTU calculator to find your exact output requirement and always match it against the radiator's rated figure at Delta T50 (ΔT50) under BS EN 442.

What sizes do mirror radiators come in?

Our mirror radiators are available in widths ranging from 280mm to 499mm and heights of 1600mm and 1800mm, giving you a selection of sizes to suit different wall spaces and room requirements. Size and dimension details are confirmed on each individual product page so you can check the fit before purchasing.

Are mirror radiators available in steel or aluminium?

Our range includes both materials depending on the model. Steel mirror radiators such as the Florence come with a 20-year manufacturer guarantee and are tested to BS EN 442 standards, while aluminium models such as the Quadro and Step heat up more quickly, require less water content, and carry a 5-year guarantee with a Trio paint technology anodised coating for durability.

What colours do mirror radiators come in?

Our mirror radiators are available in chrome, white, anthracite, and black, allowing you to choose a frame finish that complements your existing interior scheme. Colour availability varies by model, so it is worth checking the individual product page for the specific options on each radiator before purchasing.

Do I need special valves for a mirror radiator?

Mirror radiators are compatible with standard thermostatic radiator valves (TRVs), which are sold separately and not included with the radiator. Browse our full range of radiator valves covering angled, straight, and thermostatic options across a range of finishes to find the right pairing for your mirror radiator.
