Looking for a horizontal radiator around 750mm high and 500mm wide? We have 11 horizontal radiators in stock in this size from Carisa, priced from £241.06 to £1,391.28 with heat outputs from 832 to 1,409 BTU/hr (ΔT50). Actual dimensions in this group run from 700–805mm high and 480–515mm wide; the exact size, pipe centres and output of each model are on its product page.
A 750 x 500 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 cloakroom, en-suite or small box room. 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.

All figures are the manufacturers’ certified outputs to EN 442, quoted at ΔT50 — the UK standard for sizing central-heating radiators.
On heat per pound it is the Carisa Fame Horizontal Aluminium Designer Radiator: 1,400 BTU/hr for £262.63, about 5 BTU for every £1. The cheapest model on the page starts at £241.06.
It depends on the model — the range on this page runs from a cloakroom, en-suite or small box room at 832 BTU/hr up to a cloakroom, en-suite or small box room at 1,409 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 10 in white, 9 in anthracite, 3 in raw metal & stainless steel, 2 in brass & gold, 1 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.
