Questions about 1800 x 300mm vertical radiators

How much heat does a 1800 x 300mm vertical radiator give out?

Between 1,731 and 3,450 BTU/hr at ΔT50 across the 27 models on this page. The highest output here is the Colona Vertical Radiator RAL Coloured Radiator at 3,450 BTU/hr (1,012 W). All figures are the manufacturers’ certified outputs to EN 442, quoted at ΔT50 — the UK standard for sizing central-heating radiators.

Which 1800 x 300mm vertical radiator is the best value for heat?

On heat per pound it is the Neva Vertical Mild Steel Radiator: 2,164 BTU/hr for £126.94, about 17 BTU for every £1. The cheapest model on the page starts at £126.94.

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 1,731 BTU/hr up to a typical living room or a large bedroom at 3,450 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 24 in white, 22 in anthracite, 6 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.
