1500mm Wide Horizontal Radiators

We have 8 horizontal radiators 1500mm wide in stock from Carisa and Ethiant, from 300mm to 600mm high, priced from £189 to £821.38 with heat outputs from 1,869 to 5,476 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 1500mm, 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.

Between 1,869 and 5,476 BTU/hr at ΔT50 across the 8 models on this page. The highest output here is the Carisa Chambord Double Horizontal Aluminium Designer Radiator at 5,476 BTU/hr (1,606 W). All figures are the manufacturers’ certified outputs to EN 442, quoted at ΔT50 — the UK standard for sizing central-heating radiators.

Which 1500mm wide horizontal radiator is the best value for heat?

On heat per pound it is the Flat Panel Double Horizontal Radiator 600 Height: 5,398 BTU/hr for £259.20, about 21 BTU for every £1. The cheapest model on the page starts at £189.

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 1,869 BTU/hr up to a large living room or an open-plan kitchen-diner at 5,476 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 7 in white, 4 in anthracite, 2 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.
