Rated heat output and rated heat input of combustion appliances
To help develop this article, click ‘Edit this article’ above.
The heat input rate is the maximum rate of energy flow into an appliance, calculated as the rate of fuel flow to the appliance multiplied by either the fuel’s gross or net calorific value. Traditionally, the UK has used gross values, most European standards use net values. Thus for gas appliances it is now the norm to express this rating as a net value (kW (net))
