I'm looking at making an indirect hot air heating system for a 20x10ft spray booth, this needs to be done on the cheap how ever it also needs to be safe so please point out if I have missed the not so obvious area where the potential explosion will happen...
I'm planning on using the gas flame of the small workshop heater with a welding regulator (which I have already) so I will have some control over it to heat a DIY heavy steel water heat exchanger then run this through to a couple of car heater matrix's via a central heating pump. The car matrix's will heat the incoming fresh air and reheat the extracted/reclaimed heated air from inside the booth, the gas heater will be away from the booth in the next room so less chance of any thing going bang there but the question is ... what amount of water/size tank do I need in the system so that I don't end up making a steam bomb instead, is it just a case of having an expansion tank the same as a car and using a pressure valve?
