600 x 1200mm Horizontal Radiators

Looking for a horizontal radiator around 600mm high and 1200mm wide? We have 30 horizontal radiators in stock in this size from Ethiant and Carisa, priced from £171.22 to £800.54 with heat outputs from 2,428 to 9,589 BTU/hr (ΔT50). Actual dimensions in this group run from 565–600mm high and 1190–1245mm wide; the exact size, pipe centres and output of each model are on its product page.

A 600 x 1200 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 big open-plan space, or one radiator doing the work of two. 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 600 x 1200mm horizontal radiators

How much heat does a 600 x 1200mm horizontal radiator give out?

Between 2,428 and 9,589 BTU/hr at ΔT50 across the 30 models on this page. The highest output here is the Traditional 6 Column Horizontal Radiators 600 Height at 9,589 BTU/hr (2,812 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 1200mm horizontal radiator is the best value for heat?

On heat per pound it is the Traditional 4 Column Horizontal Radiators 600 Height: 6,772 BTU/hr for £361.92, about 19 BTU for every £1. The cheapest model on the page starts at £171.22.

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 2,428 BTU/hr up to a big open-plan space, or one radiator doing the work of two at 9,589 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 30 in white, 24 in anthracite, 11 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, 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.
