I see that most hot boxes are all schedule 80 coils. Is there any reason why a new burst disk and flow switch should not be installed to increase the water volume of the box.I understand that heat or temp rise could or will be lost, but since 160 to 180 degree water has been working for me at 4 gall. Would be nice to do as a 8-10 hot box is out of my price range at this time.
