Mike: Where are you going to park it? Will it be inside a building? Reason I ask is that the more wind that can get to it, the more heater you'll need. A cool breeze will blow quite a bit of heat off the block. Tossing a blanket over the engine will help retain heat from the block or even oil heater. We had a 2500 watt heater on the 4020D, and it would start down to '0'F if the batteries were fresh. I can't remember trying it lower than that. On many of the coldest days I pulled it with our '70' Diesel which would always start because it had a gasoline powered engine heater (pony motor). I have an 855 which is in the same HP range aas your 2210, and I live on North Florida, so I don't use a heater. But, on the rare occasions that it has got down to say 15* above, it never has refused to start. I5t has that little nichrome heating element in the air intake that preheats the air until the engine gets going. Years ago in Ohio, we owned several of the VW Rabbit diesel cars, and never had a block heater on them. Of course they had glow plugs, but I wired a switch from the house to the garage, and plugged in my 80,000 BTU kerosene forced air heater with a thermostat, and when my wife would turn on her hair curlers prior to work, she'd flip the switch, and by the time she walked to the garage, everything was 75*!. That was the best system I ever had! Frank
