Hello JP.
If you sail , when snowing, and
the boiler full , you may have find where your problem is, then!!
Unless using pure Propane! And still!
Attached a quick calculator sheet to allow you to know what the max volume to fill your boiler with :
Volumetric - or Cubic Thermal Expansion - Engineering ToolBoxIf the total boiler contains 800 cc (you can work it out in Gals) the total dilated volume @ 100°C will be 848cc.
You need to deduct 25/30% of void space for a safe cushion of steam on the top and to avoid draining hot water in your engine line.
So 800cc - 30% = 560cc of water should keep your nose away from problems. (
normally)
As you always work at this temp , you can keep in mind the augmentation of the volume of 50cc.
I would conclude that : "Steaming without having problem, is boring!"
Have a good time steaming in Colorado.
Cheers!
