Questions about 5,000–6,000 BTU horizontal radiators

How much heat does a 5,000–6,000 BTU horizontal radiator give out?

Between 5,014 and 5,860 BTU/hr at ΔT50 across the 24 models on this page. The highest output here is the Traditional 4 Column Horizontal Radiators 750 Height at 5,860 BTU/hr (1,719 W). All figures are the manufacturers’ certified outputs to EN 442, quoted at ΔT50 — the UK standard for sizing central-heating radiators.

Which 5,000–6,000 BTU horizontal radiator is the best value for heat?

On heat per pound it is the Odet Mild Steel Radiator: 5,118 BTU/hr for £183.02, about 28 BTU for every £1. The cheapest model on the page starts at £183.02.

What size room will it heat?

It depends on the model — the range on this page runs from a large living room or an open-plan kitchen-diner at 5,014 BTU/hr up to a large living room or an open-plan kitchen-diner at 5,860 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 22 in white, 12 in anthracite, 6 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.
