The percentage of radiation produced compared to the amount of heat produced depends on the source of heat. For example, in a typical fire, about 70-90% of the heat produced is in the form of radiation. In contrast, for electric heating sources, the percentage of radiation produced is lower as most of the heat is convective.

To calculate the output of a gas fire, you need to know the heat input rating of the gas fire in British thermal units per hour (BTU/hr) or kilowatts (kW). The heat output is typically a percentage of the heat input, commonly around 70-90%. You can calculate the heat output by multiplying the heat input by the efficiency percentage (e.g. heat output = heat input x efficiency percentage).
