 * The Energy Saving Trust has estimated that a propane patio heater with a heat output of 12.5kW will produce around 34.9kg of CO2 before the fuel runs out (after approximately 13 hours). This is equivalent to the energy required to produce approximately 5,200 cups of tea (or 400 cups for every hour of operation) Source: Friends of the Earth, Energy Saving Trust
