Questions about 600 x 800mm horizontal radiators

How much heat does a 600 x 800mm horizontal radiator give out?

Between 1,619 and 6,796 BTU/hr at ΔT50 across the 33 models on this page. The highest output here is the Traditional 6 Column Horizontal Radiators 600 Height at 6,796 BTU/hr (1,993 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 800mm horizontal radiator is the best value for heat?

On heat per pound it is the Oval Tubed Panel Double Horizontal Radiator 600 Height In White: 3,118 BTU/hr for £149.40, about 21 BTU for every £1. The cheapest model on the page starts at £100.80.

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 1,619 BTU/hr up to a large living room or an open-plan kitchen-diner at 6,796 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, 12 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.
