To avoid any overflow
No, an expansion tank is not required.
The term you are referring to is "freeboard." Freeboard is the distance from the waterline to the deck of a boat, which determines how much weight a boat can carry without submerging the deck or taking on water. A boat's freeboard is crucial for buoyancy and stability in the water.
Freeboard refers to the distance between the waterline and the upper deck level of a vessel, while buoyancy is the force that keeps the vessel afloat. A higher freeboard generally indicates that a vessel has good buoyancy, as it can displace enough water to support its weight without taking on water. Conversely, if a vessel has low freeboard, it may be more susceptible to waves and flooding, compromising its buoyancy and stability. Thus, freeboard is a critical factor in assessing a vessel's seaworthiness and performance in different water conditions.
Freeboard is the vertical distance between the waterline and the upper deck level of a ship when it is fully loaded. It is an important safety measure to prevent water from flooding the deck during rough seas or heavy weather. The freeboard requirement depends on various factors such as the type of ship, its purpose, and international regulations.
By having sufficient freeboard once the vessel's gross weight has been displaced. Freeboard is the height from water surface to the lowest point of the walls (gunnel) of the vessel. Any water that does come inboard (spray or wave over the side) needs to be pumped out of the vessel.
"all boats" have a draft, the part beneath the water. The part above is the freeboard. The part in the water is the Hull.
It is because the fresh water has less density compared to that of salt water.
I doubt it. I think you have water in your tank because it's no way how antifreeze can go in your tank unless you puuted it there. So if you have water in your tank, just buy stuff which is called dry gas. And everytime when you fill your tank add required quantity. To get rid of water in your tank you will need to do that at least 3 times, it depends on how much of water you have.
Steen Strand conceived the idea of a freeboard while doing a design project in college during the Mid 1990's. In 1998 he released two different models of the freeboard.
There has to be a tank pan under the hot water tank with a drain hooked up to the pan. If the tank leaks, it will go into the pan which will flow into the pipe that you have to have hooked up to the sewage system.
The water is fed to the house by gravity, so a pump is not required.
A pressure regulator is required on a nitrogen tank.
