Building A Co2 Lp Generator

[welj31]

Looking for a real world ideas on building a propane co2 gen.

I dont want to use tanks or food products. I do have the tools to build something. I was thinking about a wall mounted LP heater, but it would need to be changed around to get rid of heat. This would not be a problem in winter but right now it would kill the ac and the elect bill. Any help thanks

Unvented propane heaters are great CO2 generators. If you can find a model with a pilot light CO2 production in a small space isn't bad. If you have good controlable ventilation you need some fresh air source. Plan on using this in my pole barn but I have the advantage of a six foot glass door and 4x4 vented skylight in an 8x9x10 room, basically a chimney. Should work great and in the summer no electric bill.
