On my 95 E300 D the block heater has been burned out for over a year. It was 15 deg this morning and it started right up, the only time it stalled out when it was 10 below in VT and the fuel gelled. I just bought a pad heater for the oil pan but have not installed it. synthetic oil, and polar power works wonders.
