BTU Information

A BTU (British Thermal Unit) is a rating used to determine the heating or in the case of an Air Conditioner the cooling capacity of an appliance.

1 BTU is the amount of heat required to raise the temperature of one pound of liquid water by one degree from 60° to 61° Fahrenheit at a constant pressure of one atmosphere.

As a general rule we advise you to buy an Air Conditioner with a minimum 7000BTUs as this is the minimum required to call a small room (18sq/m) on a hot day. Medium rooms (24sq/m) need around 10,000BTUs and larger rooms and office spaces (36sq/m) require around 15000BTUs.

Two or more Air Conditioners may be used together if your requirements are over 15,000BTUs.
