The current block heater trigger works great if it isn't too cold. However it seems to be designed for certain types of cars that heat up quickly. In modern diesel cars the engine heater element requires longer heating times than traditional petrol engine block heaters. The current block heater trigger preheat time seems to max out around 1.5h which can be insufficient.

Official recommendations on the heating times vary. Svensk Energimyndigheten seems to recommend a maximum heating time of 1,5h regardless of engine. Their Finnish equivalent recommends a maximum of 2h for traditional block heaters and 3h for other less efficient heater types.

Therefore it would be useful to be able to set a longer maximum heating time according to the user's local conditions. In colder weather (-15 to -25 C) a heating time as long as 3 hours may be required with some cars.

I agree that this needs to be adjustable. For example my block heater takes long time to heat up the diesel engine when it's below -10 C.
