A fan assembly comprising two fans (4, 10) for supplying combustible gases to two burners (5, 9) respectively. The flow parts from the first and second burners are combined in a common manifold. Temperature censor (6, 11) detect the temperature of the gases passing through each fan, and the speed of a particular fan is increased if the temperature sensor detects reverse flow of combustion gases.

1. A fan assembly for supplying combustion gases to a burner, the assembly comprising a fan, a controller for selectively running the fan to supply the gases, in use, to the burner, and a temperature sensor positioned to monitor the temperature of the gases passing through the fan and being coupled to the controller, a further heat source with a flow path to the fan whereby the controller is arranged to increase the speed of the fan in response to the temperature sensor detecting that the further heat source has caused a parameter relating to the temperature of the gases passing through the fan to be above a threshold value.2. A fan assembly according to claim 1, wherein the parameter is rate of increase of temperature.3. A fan assembly according to claim 1, wherein the parameter is temperature.4. A fan assembly according to claim 1, wherein the controller is arranged to start the fan from rest.5. A fan assembly according to claim 2, wherein the controller is arranged to increase the speed of the fan in response to the temperature sensor detecting a temperature above a threshold value regardless of the rate of increase of the temperature.6. A fan assembly according to claim 1, wherein the further heat source is a second fan and burner assembly.7. A method of controlling a fan to supply combustion gases to a burner, the method comprising detecting the temperature of gases passing through the fan, and increasing the speed of the fan if heat from a further heat source has been transmitted to the fan, such that a detected parameter relating to the temperature of the gases passing through the fan exceeds a threshold value.8. A method according to claim 7, wherein the parameter is rate of increase of temperature.9. A method according to claim 7, wherein the parameter is temperature.10. A method according to claim 7, wherein a step of increasing the speed of the fan comprises starting the fan from rest.11. A method according to claim 8, further comprising the step of increasing the speed of the fan if the temperature is above a threshold value regardless of the rate of increase of the temperature.12. A method according to claim 7, wherein the further heat source is a second fan and burner assembly.13. A Stirling engine assembly comprising a Stirling engine heated by a first burner, a first fan for supplying combustible gases to the first burner, a supplementary heater heated by a second burner, a second fan for supplying combustible gases to the second burner, wherein flow paths from the first and second burners are combined in a common manifold, a temperature sensor for detecting the temperature of the gases passing through each fan, and a controller to increase the speed of a fan if its temperature sensor detects that a parameter relating to the temperature of the gases is above a threshold value.14. An assembly according to claim 13, wherein the parameter is increase of temperature.15. An assembly according to claim 13, wherein the parameter is temperature.16. An assembly according to claim 13, wherein the controller is arranged to start the fan from rest.17. An assembly according to claim 13, wherein the common manifold is a heat exchanger.18. An assembly according to claim 14, wherein the controller is arranged to increase the speed of the fan in response to the temperature sensor detecting a temperature above a higher threshold vale regardless of the rate of increase of the temperature.
