Questions about 600 x 900mm horizontal radiators

How much heat does a 600 x 900mm horizontal radiator give out?

Between 2,299 and 4,949 BTU/hr at ΔT50 across the 11 models on this page. The highest output here is the Carisa Tallis Double Horizontal Aluminium Designer Radiator at 4,949 BTU/hr (1,451 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 900mm horizontal radiator is the best value for heat?

On heat per pound it is the Caldaro Horizontal Aluminium Radiator: 2,721 BTU/hr for £317.34, about 9 BTU for every £1. The cheapest model on the page starts at £293.14.

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 2,299 BTU/hr up to a typical living room or a large bedroom at 4,949 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 11 in white, 9 in anthracite, 1 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.
