if both bottles are hooked together and open to each other..no matter the difference in temp..the bottles will be at the same exact pressure. When the noid opens nitrous will flow as smooth as ever. No reason why it wont. As long as the liquid nitrous in each bottle covers the dip tube.
But...what Dave is talking about....if you have two bottles open to each other...and one has a heater...first it will be twice as hard to raise the pressure...and second...the bottle with the heater will have the nitrous that is expanding...this will force additional volume of liquid nitrous into the cold bottle. Then when you spray its still not a problem...until you get down to a certain point. At some point the bottle with the heater on it will have mostly gaseous nitrous and the bottle without the heater will still have liquid. Both will still be at the same pressure, and the contents of each will still want to flow out when the noid is opened. Problem is one will be gas and one will be liquid. At this point..when you spray...youll probably get a mix of liquid and gas nitrous resulting in a inconsistant hit. You could probably find out how low you can go by hooking up two bottles fully serviced. Say two ten lb bottles that when fully serviced have a total weight of 25 lbs. Hook up the heater to one and raise the pressure of both bottles with both valve open to the desired pressure. Then close the valves and weigh them. See home much nitrous has transfered out of the heated boittle. It may only be a lb or two. However...once you sprayed and the pressure dropped....and you then heated up the bottle with the heater again...it would again be transfering nitrous into the cold bottle. So as you sprayed and raised the pressure each time...you would be compounding the problem. So it would be tough to get a good idea of when you would have problems. But I bet on a cool day youd get inconsistant hits after probably 1/2 the volume is gone. May as well have just gone with one bottle at that point.
Best to have both bottle open and both with heaters....or just open one at a time and swap heaters. making sure you never have both bottle open at the same time if your doing the swap method.
