On my Vision, I have installed an electric carburetor heater. the instructions say to use heat on take off. The fact that the electric heater does not heat the incoming air but instead the carb throat, the prophylactic use of heat at takeoff shouldn't degrade power and so imo, given that takeoff is the most power critical stage of flight, use of heat is a good idea.
The accident report is (relatively) open on the possibility of ice as the cause of power loss but it then leaves a mystery as to what other factors may be in play. Perhaps use of heat, in my case, is a judicious course to follow.
