The Reina Coneva horizontal designer radiator carries the same rounded, two-column tube profile as the vertical range into a wall-hugging 550mm-high format. Six widths are available – 440mm, 580mm, 790mm, 1000mm, 1210mm, and 1420mm – each in a classic matt white (RAL 9016) or modern textured anthracite (RAL 7016) finish, built from mild steel.
Unlike the taller vertical Coneva models, this horizontal range is suitable for central heating, dual-fuel, and electric-only systems, making it a flexible choice for bathrooms, cloakrooms, and utility spaces. Every model is supplied complete with wall brackets and fixings, manufactured to BS EN 442, and backed by a 5-year guarantee from Reina.

Recommended Radiator Valves
Reina recommends pairing this radiator with a matching Reina Modal TRV valve set (thermostatic radiator valve and lockshield, sold as a pair) in angled, straight, or corner configuration to suit your pipework. Choose a white valve set for the white colourway, or an anthracite valve set to match the anthracite finish. Valves are sold separately and are not included with the radiator.
Are radiator valves included with this radiator?
No. All widths in the horizontal Coneva 550mm range are supplied without valves. Reina recommends a matching Modal TRV valve and lockshield pair, chosen in angled, straight, or corner configuration to suit your pipe layout.
Can this radiator be used on an electric or dual-fuel system?
Yes. Unlike the vertical Coneva range, the 550mm horizontal models are suitable for central heating, dual-fuel, and electric-only systems, making them a flexible option where a wet heating supply is not available.
What is the difference between the Reina and UK Standard output figures?
Reina publishes its own output figures at ΔT70, while the current European and UK standard rating is ΔT50. The ΔT50 figures in the table above give the more realistic comparison against other manufacturers' radiators.
Which width should I choose for a small cloakroom?
The 440mm or 580mm widths are the most compact options in the range and suit smaller cloakrooms and utility spaces, while the 1210mm and 1420mm widths deliver higher output for larger bathrooms.
What is included in the box?
Each radiator is supplied with wall-mounting brackets and fixings. Valves, pipework, and bleed accessories are ordered separately.
What guarantee does this radiator carry?
Reina provides a 5-year manufacturer's guarantee against manufacturing defects, provided the radiator is installed and maintained correctly.
