Introduction: Forced Air Heater Under $100 DIY Wood Frame

FIGHT HIGH HEATING OIL prices and save money for other things like paying your mortgage or refinancing your home. Hope this helps:-) Note: Look T THE VIDEO RESPONSES THEY ARE VERY GOOD! This is a prototype easy to build rooftop forced air heater that produces 45 degree increases at a high CFM CFPM rate. This one is made out of cardboard. A real one can be made out of weather proof material COROPLAST.

Pretty cool, but how well does this method work during the night?

This approach looks pretty interesting... using air for heat transfer instead of the standard water/oil.

I know with my shop-vac (Earlex brand), a fair amount of heat is generated when the machine is under load and a lot of it comes out outlet port. It might be interesting to have one thermometer on the air leaving the vac and another on the air leaving the air-frame, just to measure the difference.

Also, assuming it wouldn't overload the unit, this would be a great approach to combine with, say, a whole-house built in vacuum system. The compressor/air-mover would (I assume) be much more efficient, in terms of air displacement/energy used and it would do double duty, in terms of heating AND helping to keep the house clean.

As well, it would have built-in air filtration, ensuring that the roof-unit wouldn't get clogged with airborne dust and debris.

Great food for thought!
