i cannot see any harm in warming up a realy cold engine at all , also a double dose of the heater plugs wont harm the engine, only thing it will do is take a little more charge out of the battery and if your battery is up to the job no probs . only thing i would not use is easy start, as engines can come to rely on it they get hooked on it ,i dont know why but ask any old mechanic not these modern fitters that seem to call themselves mechanics nowadays, or diesel owner and they will tell you the same
