We have 3 horizontal radiators in stock in this size from Ethiant, priced from £111.60 to £339.48 with heat outputs from 2,159 to 5,118 BTU/hr (ΔT50). Actual dimensions in this group run from 570–600mm high and 540–540mm wide; the exact size, pipe centres and output of each model are on its product page.
A 600 x 550 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 2,159 and 5,118 BTU/hr at ΔT50 across the 3 models on this page. The highest output here is the Aron Aluminium Radiator at 5,118 BTU/hr (1,500 W). All figures are the manufacturers’ certified outputs to EN 442, quoted at ΔT50 — the UK standard for sizing central-heating radiators.
Which 600 x 550mm horizontal radiator is the best value for heat?
On heat per pound it is the Oval Tubed Panel Double Horizontal Radiator 600 Height In White: 2,159 BTU/hr for £111.60, about 19 BTU for every £1. The cheapest model on the page starts at £111.60.
What size room will it heat?
It depends on the model — the range on this page runs from a bedroom, home office or small kitchen at 2,159 BTU/hr up to a large living room or an open-plan kitchen-diner at 5,118 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.
What colours and finishes are available?
In this group we have 2 in white, 1 in anthracite, 1 in black. Colour is chosen as a finish option on the product page.
What else do I need to fit it?
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.
