The heat power can be calculated as in the following example:
We consider a headroom of at least 5dB (1/3 of full power) and a 4 ohms load on an amplifier
producing 650 watts per channel. The 1/3 power per channel is accordingly 650 / 3 = 217 watts, and
total output 2 x 217 = 433 watts.
The power consumption according to the chart above is then 1330 watts. This chart shows the active
power consumption of the amplifier with different loads and power levels.
The heat power produced is the difference between the power consumption and output power:
1120 - 433 = 687 watts per amplifier.
The chart below shows the heat power produced in watts, in kcal per hour, and also in BTU per hour.

The efficiency can also be calculated, it being the output-power divided by the input-power:
433 watts / 1120 watts= 39%.
