I would imagine that you are asking about an older vehicle heater, since there is a big difference between a heater that uses a blower motor resistor, than a system that uses a computer controlled automatic heater system. In an older one with a blower resistor, most of them are wired so that the cur...

My recommendation would be to mount a thermostatic switch somewhere on your corn burner that would automatically run the lp furnace fan when the corn burner is hot and shut it off when it cools below some temperature. These switches can handle up to 15 amps at 120 VAC and cost less than $50. h...

Does this help? design of the ductworks in ventilation systems are often done by using the * Velocity Method * Constant Pressure Loss Method (or Equal Friction Method) * Static Pressure Recovery Method The Velocity Method Proper air flow velocities for the a...

Greetings All, Is the fan salesman lieing to me? I tell him I need a 7-8 foot diameter fan that will produce at least 100 mph wind speed, he says his fan will do it, but the specs say it only does 365000 cfm., my math says this fan will only produce 26.95 mph. The question is am I using t
