Anyone ever use liquid co2 tank for supplimenting co2 instead of a burner or gas tank?

I never really ran co2 in my rooms but recently purchased a CO2 burner and had great results keeping the PPM at 1400 for the first half of flower. But damn does it give off a ton of heat. I stay away from the regular gas cylinders as I would need to replace it prety much every day or two. But I was looking into liquid co2 tanks as they hold about 30x the amount of co2 as the standard gas cylinders.

Im curious to as why it is not used more often. Does anyone have experince using these larger tanks or know of anyone who ever has?
