Where is the best place for the expansion tank on a pressurized glycol system?
When locating the expansion tank you must check the pressures in the system, when the pump is on and off and when the system is cold or hot. The typical location for the expansion tank is on the suction line of the chilled water pump, near or on the fill line.
Where is the best place to put an expansion tank in a house?
The tank can be installed anywhere in the cold-water line between the house’s main valve and water heater, or on the hot-water line within 3 ft. to 5 ft. of the water heater.
Is the orientation of an expansion tank with..?
Most smaller tanks are designed to be supported by the plumbing, when installed in the vertical orientation. The most common recommendation seems to be, to install the tank vertically below the plumbing. You’ll want to check the manufacturer’s installation instructions, to determine how to properly install the specific tank you’re using.
When to pressurize the expansion tank before adding water?
Pressurizing the air side of the tank to equal the static pressure of the water at the expansion tank location and before adding water to the system. This prevents cold water from partially compressing the air in the tank. The diaphragm only begins to compress when the water temperature rises. 2.
Why do you need an expansion tank for a water heater?
ABBAUSA | Jun 07, 2018 02:08pm | #4 In our City, the Expansion Tank is absolutely required because the City Water Lines now has check valves so the cold water only flows into the house. As the tank water heater does its job, of course, the water expands. Without the expansion tank, the T&P valve leaks some water.
Where do you put an expansion tank on a water heater?
Expansion tanks are normally installed above the water heater on the cold water line before it enters the water heater; however, they can really be installed anywhere on the cold water line prior to entry into the water heater.
Where is the best place to mount an expansion tank?
If the tank needs to be near a hydraulic separator it is best to mount it from a tee in either pipe connecting to the lower sidewall connections on the separator, as shown in Figure 5. 3. Do not Overheat It: Whenever possible, avoid locating expansion tanks in close proximity to very hot water.

How does an expansion tank ( CHW ) work?
It is simply a closed tank with a connection to the chilled water system. The closed tank has extra space that is filled with air, when the temperature in the system is cold. As the temperature within the chilled water system rises, the volume expands and fills the empty space within the tank. Expansion Tank (CHW)-4
