500 x 1000mm Horizontal Radiators
Looking for a horizontal radiator around 500mm high and 1000mm wide? We have 5 horizontal radiators in stock in this size from Ethiant, priced from £164.28 to £406.01 with heat outputs from 3,124 to 6,824 BTU/hr (ΔT50). Actual dimensions in this group run from 500–500mm high and 965–990mm wide; the exact size, pipe centres and output of each model are on its product page.
A 500 x 1000 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.

Questions about 500 x 1000mm horizontal radiators
How much heat does a 500 x 1000mm horizontal radiator give out?
Between 3,124 and 6,824 BTU/hr at ΔT50 across the 5 models on this page. The highest output here is the Odet Mild Steel 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.
Which 500 x 1000mm horizontal radiator is the best value for heat?
On heat per pound it is the Odet Mild Steel Radiator: 6,824 BTU/hr for £215.50, about 32 BTU for every £1. The cheapest model on the page starts at £164.28.
What size room will it heat?
It depends on the model — the range on this page runs from a typical living room or a large bedroom at 3,124 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.
What colours and finishes are available?
In this group we have 5 in white, 1 in anthracite. 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, and column radiators in this group can be fitted with feet where the wall will not take the full weight. Delivery to mainland England and Wales is free.
