Energy Efficient Products

On the energy label, the direct heat output needs to be displayed: should this be the gross calorific value or the net calorific value?

The heat output is independent of net or gross calorific value. The difference between net and gross calorific value affects the fuel input (for example energy efficiency or emission requirements).
