How does a boiler water feeder work?

What is Vxt for boiler?
In addition to this added convenience, The VXT is the first automatic steam boiler water feeder designed to monitor the amount of water added to a steam boiler. The addition of make-up water raises the oxygen level in a boiler and accumulates lime and other mineral deposits.
How does a low water cut off work?
A low-water cutoff is a mechanical device (usually a float switch) that is used to turn off the burner or shut off fuel to a boiler to prevent it from running once the water drops below a certain point. If a boiler is “dry-fired” (burned without water in it) it can suffer rupture or catastrophic failure.
How does a water feeder work?
Most water dispenser work by having a 5-gallon water bottle upside down on the top of the machine. This allows gravity and vacuum pressure to do the job of filling a glass when someone presses water spigot. When this happens, air is allowed into the bottle so water can escape into your glass or bottle.
What is a boiler water feeder?
Most residential steam boilers have an automatic water feeder that adds water to the boiler in the event that the boiler’s low water cutoff device says it needs some water. This is not as much a safety item as it is a convenience item.
How does an automatic water feeder work?
It works by sensing the fact that water is stacking up in the piping and exerting downward pressure. Once enough downward pressure is exerted to cause the switch to ”open” then the feeder is physically disconnected from its power source.

ASME (American Society of Mechanical Engineers) Steam heating boilers of any size, regardless of where they are installed, must have a low water cut-off per ASME BPVC. IV. The same code only requires that hot water boilers with input greater than 400,000 btu must have a low water cut-off.
