My first Benz, a 220D, came from Minnesota with a heater just like yours. I used to set the heater on high, open both the floor vents and the defroster vents, plug the engine heater in at night, and would find the windshield partially clear of frost/ice in the morning from the air convection in the heater box. I've since switched to Mobil 1 and don't use a block heater any more ---

Several years ago, we used circulating engine heaters that were used when it got cold in Alaska (also common in Northern states and Canada). These typically were "T" ed into a heater return line to the engine block.and had an input connected to an engine block drain. They came in 500, 750, 1000, and 1500 Watt sizes, and were very effective in keeping the engine toasty even in -40F weather. I used a 1000 W unit on my 390 c.i. V-8, and a 750 W unit on my 289 c.i. V-8. Actually, about 30 minutes of operation were enough to let the engine start easily, but mostly they stayed plugged in all night, so that the driver had instant heat when the car started. Fairly inexpensive and very effective, they looked like a soup can with an AC cord coming out the side, and 2 - 5/8" hose connections. Usually mounted low alongside the engine, to make best use of the convection heating currents. Werner
