What is a BTU?

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 7,000BTUs as this is the minimum required to cool 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.
