The new Grainger catalog #392 has industrial, electric heat guns and blowers for under $150 that may suffice to warm up engines under certain conditions. If someone is willing to give it a try, you may have an inexpensive engine warmer for mild winter weather. Look on P. 1814 at the Industrial Heat Gun #4Z714 by Master Appliance (23 CFM volume; 3ooo velocity fpm, 12 amps, 120v, temp range of 300-500F) Weighs only 4 lbs). Another similar model is 47 cfm. The first one is $77.65 and the second one is $136.15. If you have electricity, this may work once you attach the proper hose. Perhaps, our engineers in the crowd could give us some insight. Grainer also has some oil and propane heaters with electric blowers that would probably be more effective.
12 amps and 120 volts sounds like a little less heat out than a 1500 watt hair dryer that comes with built-in ground fault interupt and overtemp protection with a fraction of the cost and weight.
