How much heat could I produce if I assembled four 25 ohm, 25 watt, Cement Type Wirewound Resistors in front of two fans in a 4 cubic foot space? I was planning on housing them turned 45 degrees (for better aerodynamics) in a small metal box with two 2 inch fans recirculating the air in the enclosure over the resistors.
Thank you very much! Now all I have to do is tackle my first actual electronics build since 2004 during my naval training. This is just as simple as 12v (with the apropiate amperage) power source and a on off toggle and an inline fuse right?
I have placed a 10W lamp in a small foam beer cooler, and the insides got well over 100degF. With 100W, you will start a fire, or a least create a molten puddle of urethane...
You dont need the fans. Convection will stir the air such that the temperature will be quite uniform. Or dump the resistors, and use only the fans. They dissipate about 3W apiece, which will just about heat the box by themselves....
I knew someone would take it over my head. lets just say I solder these up in parallel and supply them with a 4.5 amp fused 24 volt source then hook the 500ma source I already have for my fans and switch the power on it will all work?

Guess I'll drop that to two resistors and build it from wood. I am building a brooder for my hatch and I'm kind of on this build my own ^%*$ kick. Keeps me off the streets and occupied at work.
Yes I need help I thought that's what this forum was for. I am a diy kind of guy and you guys are experts. I apologize if I need more help than the more technically savvy members.
