My water heater is a propane burner, runs off a 500 gallon underground tank.
Is this idea crazy:
If I got one of those valves that Hydro Innovation sells and put it on a hot water line in my bsmt, could I rig a co2 controller to open that valve on the hot water when needed , therefore creating co2 with my tankless heater? My house has a deep well, if I could re-circulat that water back to my well somehow and get some kind of flange on the vent to the heater(which now vents outside) to direct the output to my room when the valve is on, am I nuts or would this work?
Seems like there has to be a way to use what I already have.
