In most instances, one or two bedroom radiators will be sufficient to adequately heat the space. That said, especially large bedrooms could require more.
You can make use of our BTU Calculator to work out what sort of heat output is needed to warm the room up to a comfortable temperature. Simply divide the total BTU requirement by the number of radiators to work out the average BTUs required per radiator.
For an insight into some of the best bedroom radiator options available, take a look at our Advice Centre blog, The Top 7 Radiators For A Small Space.
