High BTU consumption and longer distances need higher-gauge tubing.
There are online calculators.
Generally yes.tx2sturgis said:Quarter inch copper tubing is generally suitable for any reasonable length and normal use in an RV/tiny house/van/trailer.
I suggest a 1/2 line with 3/8" lines tee'd off that one (seen Many RV's especially older ones that use this )...................I doubt most people would EVER put enough useage on that to make any difference..............John61CT said:For a small Wave heater and a campstove in a small van that would be unnecessary.
No harm though, just saying, depends on the setup, just like with electrics, not hard to actually do the math.
