I went to my independent auto truck store and have them order me a Cab Heater. I have two of them mounted way back on the fire wall below the dash in front of the driver side and the other on the passenger side.
This units can also be purchase at the large truck tractor places too. The on the road truckers use them in there cab and sleeper. They can park over night at one of those truck stops that have power inputs to keep there cab and camper heated or air condition without having the truck idle. You can get them in any voltage from 12 and 24 VDC and 120 VAC 60 hz. The only difference between the heaters, is that the fan motor are different voltages. Large on the road trucks and utilities vehicles may have a inverter in them which takes the 12 or 24 VDC from inverter-alternator which changes it to 110 vdc 7kw and than invert it to 120 vac 60 hz 5kw which are normally use in the ambulances. I have a 640 watt heater on the driver side and a 860 watt on the passenger side. Each has a thermostat control. I just turn them all the way up and used a heavy duty 30 amp three position rocker switch to either select one heater or both heaters for a 120 volt 60 Hz units which draws about 6 to 9 amps. My vehicle has a air circulation mode where the heated air that normally comes from the engine coolant is damper off. The 12 vdc vehicle heater blower still can be use to circulated the air in the cab. The existing vehicle blows this air into the cab with ducts on driver side and on the passenger side or can choose either side. These cab heaters are mounted just behind and below these duct outlets. For me, the 120 vac heaters are handy. I can either select the onboard power or out board power with a three position selector switch. The outboard power comes through the main plug in which is 4 wire that has a neutral wire for 120 vac. About 15 minutes before I leave while it park in the garage, I turn on just the 640 watt heater which will rise the cab temperature is up to 80 F. In the garage, I do not have to turn on the circulation fan which can also be directed in defrost mode to the windshield. I find it only takes about 50 F degree air to start to defrost the windshield. Any temperature down to 0F, it still only takes the 640 watt heater and the air circulator and direct this heated air to the windshield. I rework the fan blower speed so it is on super blow you hair back mode for a quick defrosting action. I can drive 2 blocks and the all the vehicle glass is clear. So far for the last two winters here in Montana which was warmer than normal, the outboard power to preheat the heaters was enough to drive up to 6 miles before I had to turn on cab heater.

Is there a ceramic heater that's fairly efficient that's coupled with a fan unit. Or a good drawing or diagram of how to gang the two-- fan and heating unit- to blow onto the windscreen? -------------- next part -------------- An HTML attachment was scrubbed...
