1200mm Wide Horizontal Radiators

We have 47 horizontal radiators 1200mm wide in stock from Carisa, Ethiant and Reina, from 295mm to 750mm high, priced from £101.84 to £800.54 with heat outputs from 1,352 to 9,589 BTU/hr (ΔT50).

Width is what a radiator has to fit; height and panel depth are what give it output. If the wall only allows 1200mm, go taller or choose a double-panel model rather than settling for less heat. 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 1200mm wide horizontal radiators

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

Between 1,352 and 9,589 BTU/hr at ΔT50 across the 47 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 1200mm wide horizontal radiator is the best value for heat?

On heat per pound it is the Traditional 4 Column Horizontal Radiators 750 Height: 8,465 BTU/hr for £405.60, about 21 BTU for every £1. The cheapest model on the page starts at £101.84.

What size room will it heat?

It depends on the model — the range on this page runs from a cloakroom, en-suite or small box room at 1,352 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 47 in white, 25 in anthracite, 13 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.
