What are Watts and BTU's?

watts and btu definitionWatts: A measure of power or the rate of energy consumption by an electrical device when it is in operation, calculated by multiplying the voltage at which an appliance operates by the current it draws (Watts = Volts X Amperes).

BTU's: Stands for British Thermal Units. Homes are measured to determine the number of BTU's required from a cooling or heating system. The larger the BTU rating, the higher the heating capacity of the furnace or air conditioner.
