Does the expansion vessel go on the flow or return?
The Expansion Vessel must be fitted to the Return Side of the Central Heating System and in such a way that there can at no time be an obstruction between the vessel and the system.
Can you install expansion tank upside down?
Expansion tanks can be installed in any direction. Whether oriented uprightly, horizontally, or even upside down, the expansion tank will function properly without any adverse effects. When putting an expansion in an abnormal position (specifically sideways or horizontally), make sure to support the tank.
Where should the expansion tank be installed on a boiler?
The expansion tank is installed on the supply-side of the boiler system. Its sealed-in air pre-charge prevents water from entering the tank until the system pressure begins to rise. 2. As the water temperature rises, water enters the expansion tank.
What is the correct pressure in an expansion tank?
The recommended water pressure is between 50 and 60 PSI. Thermal Expansion Tanks contain an air bladder which is pressurized with air, and expands and contracts to absorb the expanded water from the water heater. needed. Check the air pressure in the Expansion Tank using a tire gauge.
How should an expansion tank be mounted?
An expansion tank is generally installed directly above the water heater by means of a tee-fitting installed in the cold water delivery pipe. The expansion tank is usually installed vertically, though it is acceptable to install it horizontally if it is necessary because of space limitations.
Can an expansion vessel be installed horizontally?
The expansion tank may be installed vertically (preferred method) or horizontally.
What pressure should an expansion vessel be set to?
Summary. Expansion vessels, also known as expansion tanks, keep the pressure in a combi boiler stable while water heats and cools. They are typically located inside the boiler casing. The typical pressure a boiler system should be set to is 1 bar.
Do expansion vessels need flushing?
All expansion vessels on hot and cold water domestic systems require flushing.
Does expansion tank go on hot or cold line?
Although expansion tanks can be installed on the hot side, we strongly recommend they be installed on the cold line, downstream of the shutoff valve.
Can you install expansion tank anywhere?
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. An expansion tank should be installed in conjunction with a pressure-reducing valve in high-pressure situations.
