500mm High Horizontal Radiators

We have 13 horizontal radiators 500mm high in stock from Carisa, Ethiant and Reina, from 425mm to 1800mm wide, priced from £110.44 to £2,120.40 Heat outputs run from 739 BTU/hr for the slimmest models to 8,376 BTU/hr for the widest doubles, so there is a 500mm radiator here for anything from a cloakroom, en-suite or small box room to a big open-plan space, or one radiator doing the work of two.

Height is the first thing to fix when you choose a horizontal radiator: it decides whether the radiator clears a window sill, a worktop or a dado rail, and it sets the pipe centres if you are replacing an existing radiator. Once the height is right, use the width and the BTU figure to get the output the room needs. 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 500mm high horizontal radiators

How much heat does a 500mm high horizontal radiator give out?

Between 739 and 8,376 BTU/hr at ΔT50 across the 13 models on this page. The highest output here is the Traditional 6 Column Horizontal Radiators 500 Height at 8,376 BTU/hr (2,456 W). All figures are the manufacturers’ certified outputs to EN 442, quoted at ΔT50 — the UK standard for sizing central-heating radiators.

Which 500mm high 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 £110.44.

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 739 BTU/hr up to a big open-plan space, or one radiator doing the work of two at 8,376 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 12 in white, 7 in anthracite, 5 in black, 1 in raw metal & stainless steel. 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.
