Looking for a horizontal radiator around 600mm high and 700mm wide? We have 20 horizontal radiators in stock in this size from Carisa and Ethiant, priced from £243.29 to £650.26 with heat outputs from 1,665 to 6,824 BTU/hr (ΔT50). Actual dimensions in this group run from 570–600mm high and 660–745mm wide; the exact size, pipe centres and output of each model are on its product page.
A 600 x 700 horizontal radiator is the size most UK homes were built around, so it usually replaces an existing radiator without moving the pipework, and the highest-output models here will heat a large living room or an open-plan kitchen-diner. Every model is in stock for free delivery to mainland England and Wales, and each product page shows the certified heat output for every size so you can match it to your room with our BTU calculator.

Between 1,665 and 6,824 BTU/hr at ΔT50 across the 20 models on this page. The highest output here is the Aron Aluminium Radiator at 6,824 BTU/hr (2,000 W). All figures are the manufacturers’ certified outputs to EN 442, quoted at ΔT50 — the UK standard for sizing central-heating radiators.

It depends on the model — the range on this page runs from a bedroom, home office or small kitchen at 1,665 BTU/hr up to a large living room or an open-plan kitchen-diner at 6,824 BTU/hr. A well-insulated modern room needs far less than an older one with single glazing and an outside wall, so use our BTU calculator with your room’s measurements before you choose.
In this group we have 20 in white, 15 in anthracite, 8 in black. Colour is chosen as a finish option on the product page.
A pair of radiator valves (a thermostatic set is the usual choice) — see our valves and accessories. Wall brackets are supplied with every radiator. Delivery to mainland England and Wales is free.
