The Reina Slimline Vertical Radiator is a mild steel designer radiator with a single, ultra-slim 13mm flat-fronted panel that keeps floor space free while making a clean, contemporary statement. Offered in 11 sizes from a compact 470mm x 300mm up to a full-height 1770mm x 500mm, and in White or textured Anthracite, it suits hallways, living rooms, bedrooms, kitchens, bathrooms and home offices.
The 50mm pipe centres put both connections together at the bottom centre of the panel, so the radiator sits neatly in narrow wall spaces without extra width taken up by valves at the sides. Reina publishes heat output at both ΔT50°C and ΔT30°C, making it straightforward to size for a boiler or a lower-temperature heat pump system, and every radiator carries a 5-year manufacturer guarantee.
Designed for central heating only, it can be finished with an optional height-adjustable chrome towel bar (sold separately) and paired with the recommended Reina Modal TRV or Drayton TRV4 valves shown below.

Central Heating Only
This radiator is suitable for central heating (wet) systems only. It must not be fitted with electric or dual-fuel heating elements or valves.
Sizing Tip: Compare Outputs at the Right Temperature
Outputs on this page are the manufacturer's published figures at ΔT50°C (the current UK and European rating) and ΔT30°C, which is more representative of low-temperature heat pump systems (for example a 55°C flow and 45°C return in a 20°C room). Older brochure figures quoted at ΔT70°C look noticeably higher but are not like-for-like, so always size against the ΔT50 or ΔT30 columns.
Ultra-slim flat panel
A single, smooth flat-fronted panel just 13mm deep gives a crisp, minimal profile. The front of the radiator sits 62-87mm from the wall, so it stays unobtrusive in hallways and alcoves.
Durable mild steel
Made from robust mild steel for efficient heat transfer and a long service life, finished in White or textured Anthracite to suit modern and traditional interiors alike.
Bottom-centre connections
50mm pipe centres keep both connections together underneath the panel, which is ideal for awkward or narrow wall spaces where side-mounted valves would not fit.
Heights from 470mm to 1770mm
Choose 300mm, 400mm or 500mm widths and heights of 470, 770, 1170, 1470 or 1770mm to match the wall space, from a compact cloakroom to a full-height feature in a living room.
Output published at ΔT50 and ΔT30
Manufacturer outputs at ΔT50°C and ΔT30°C let installers size confidently for boilers and low-temperature heat pump systems alike.
5-year guarantee
Backed by a 5-year manufacturer guarantee for confidence in the long-term quality of the radiator.

Recommended Valves & Accessories
The Slimline is supplied without valves, so you will need a pair for each radiator. Reina's own recommendation is the Reina Modal TRV, a designer thermostatic valve and lockshield set that matches the flat, minimal look of the panel. If you prefer a conventional, widely stocked thermostatic option, the Drayton TRV4 is a proven alternative.
Valves Not Included
Radiator valves are sold separately. Choose a valve pair from the recommended options below and match the finish to your radiator.
Reina Modal TRV (recommended)
A 15mm x 15mm designer thermostatic radiator valve and lockshield with a brass body, 7-28°C temperature range, frost protection, positive shut-off and a bi-directional valve body. Rated to 10 bar and available in angled, straight and corner versions in White and Anthracite to match the radiator.
Drayton TRV4 (alternative)
Britain's best-known thermostatic head: a liquid-filled sensor, 10-30°C setting range, frost protection at approximately 8°C, a range-limiting pin and non-stick valve internals. Two-pipe bodies include pre-setting so the radiator can be balanced at the valve. 15mm compression inlet with a ½" BSP outlet, 10 bar maximum static pressure, available in white and chrome.
Reina Portland manual valves
Prefer simple on/off control? The Reina Portland 15mm manual valve pairs (angled or straight) suit a room already controlled by a room thermostat or smart zone control, and come in White, Chrome and Anthracite.
Reina Crova corner valves
The Reina Crova corner valve pair routes pipework in from the side or floor in tight positions, and is offered in White, Chrome and Anthracite finishes.
Check Valve Compatibility
Valve outlets must suit the radiator tappings. Check the valve's connection type before ordering, and match the finish to your radiator: White valves for white radiators and Anthracite valves for anthracite ones.
