DTW is definitely the way to go when running the water-cooled co2 Gens. Your tap water should be sufficient for running DTW with the wastegate valve.
Running them closed loop is highly inefficient. At that point you might as well just run a regular burner and compensate for the additional heat it produces w/ air conditioning.
