BTUs are ‘
British Thermal Units
‘, the unit in which radiator efficiency is measured. Factors such as room dimensions, window size and wall material are used to calculate the required outputs of radiators, in order to adequately heat a room. Use our BTU Calculator to determine the heat requirements of your room.
What size BTU radiator do I need?
The amount of BTU’s required per radiator will depend on how many radiators are within the room – so
divide the total BTU requirement by the number of radiators
to calculate the average BTU’s required per radiator.
How many BTU do I need for my room?
| Area To Be Cooled (square feet) Capacity Needed (BTUs per hour) | 100 up to 150 5,000 | 150 up to 250 6,000 | 250 up to 300 7,000 | 300 up to 350 8,000 |

How do I work out what size radiator I need for a room?
A quick and easy way to calculate the size of the radiator required for any room in your house is by
measuring the room in cubic feet and then entering the information into a BTU (British Thermal Units) calculator
found at the base of this page or using the table below to estimate the total BTU’s required to correctly …
Is a higher BTU radiator better?
BTU stands for British Thermal Unit(s). This tells you how much heat a radiator can put out. A BTU is how much energy is needed to heat around a pint of water by one degree (farenheit).
The higher the number of BTUs the quicker the radiator will be able to heat the space around it
.
How many BTU do I need for a 20×20 room?
| Room/Area Size: Examples: Recommended BTU: | 100-200 sq ft 10×12-10×20, 12×15, 14×14 rooms 6,000 BTU | 200-300 sq ft 10×20-15×20 rooms, efficiency apartment 8,000 BTU | 300-400 sq ft 15×20-20×20 rooms, studio apartment 10,000 BTU | 400-500 sq ft 20×20-20×25 rooms, 1-bedroom apartment 12,000 BTU |

Can a radiator be too big?
If your radiator is too big,
it will minimize essential wall space and use excess energy whenever it is in operation
. By contrast, if your radiator is too small, it won’t have the capacity to properly heat your space to the required temperature.
Is 6000 BTU enough for a bedroom?
If you want to properly cool down a
300
square foot area (or room), you need a 6,000 BTU air conditioner. Obviously, the problem arises when you have a tiny 12×12 room, for example. According to the US Department of Energy directive, an air conditioner’s most appropriate size would be 2,880 BTU unit.
What size room will 12000 BTU cool?
12,000 BTUs will cover
400 sq. ft.
(3,200 cubic feet)
What size room will 9000 BTU?
| Area To Be Cooled Capacity Needed (BTUs Per Hour) | 300 to 350 square feet 8,000 BTUs | 350 to 400 square feet 9,000 BTUs | 400 to 450 square feet 10,000 BTUs | 450 to 550 square feet 12,000 BTUs |

What type of radiator gives out the most heat?
Aluminium radiators
provide the highest potential BTU output possible. That doesn’t mean that every aluminium radiator has a higher heat output than every steel radiator, for example. But aluminium radiators have the greatest heat output potential of any type.
What’s the difference between a Type 21 and Type 22 radiator?
The main difference between Type 21 and Type 22 radiators is
the layers of fins
, also known as the number of convectors. Type 21 convector radiators feature 2 panels which encase a single layer of fins. … A Type 22 radiator is therefore generally wider than a Type 21 radiator.
How do I choose radiator size?
It’s recommended that you choose a
radiator size that is within a 10% range of your BTU requirement
. However, if it is a choice between buying a radiator that is a little on the small side vs one that is slightly too big, it is best to oversize and buy one that is too large.
Does BTU matter for radiators?
A radiator’s output is measured in British Thermal Units, more commonly referred to as BTUs.
The higher the BTU rating of a radiator, the more heat output it will generate
. … Rooms with more doors and windows (especially single glazed ones) will need radiators with a higher BTU value than those without.
Does higher BTU mean more heat?
In a heat pump or furnace, the BTU number refers to the heat output of the particular unit. The
higher the number the more heat the unit can produce
. … The larger your home, the higher the BTU you will want because it means the heating or cooling unit will be able to produce more heated or cooled air.
What happens if BTU too high?
If the BTU is too high,
your room will cool too quickly and that can cause the air conditioner to cycle more often
. That places a considerable amount of load on the compressor and can shorten the lifespan of the air conditioning unit.
