Questions about 3,000–4,000 BTU radiators

How much heat does a 3,000–4,000 BTU radiator give out?

Between 3,000 and 3,987 BTU/hr at ΔT50 across the 105 models on this page. The highest output here is the Piatto Vertical Aluminium Radiator at 3,987 BTU/hr (1,169 W). All figures are the manufacturers’ certified outputs to EN 442, quoted at ΔT50 — the UK standard for sizing central-heating radiators.

Which 3,000–4,000 BTU radiator is the best value for heat?

On heat per pound it is the Odet Mild Steel Radiator: 3,412 BTU/hr for £138.74, about 25 BTU for every £1. The cheapest model on the page starts at £137.27.

What size room will it heat?

It depends on the model — the range on this page runs from a typical living room or a large bedroom at 3,000 BTU/hr up to a typical living room or a large bedroom at 3,987 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 92 in white, 67 in anthracite, 25 in black, 3 in chrome, 2 in brass & gold, 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.
