Why expansion tanks need to be understood | Contractor

The first expansion tanks on the old gravity systems were nothing more than copper-lined, open-top tanks located above the highest part of the heating system. As the water expanded, it filled the tank in the attic with the expanding fluid. If the tank overflowed because of excessive fill, the excess water spilled into the gutter of the attic.

What is an Expansion Vessel? | Viessmann

Depending on where it is situated, complex parts of your boiler may have to be taken out in order to get to the vessel. In some cases, the boiler needs to be taken off the wall in order to fit a new expansion tank, and this involves disconnecting the flue. So, if you need to replace this part of your boiler, make sure you call a heating engineer.

plumbing - What is the Correct Hot Water Expansion Tank

Most expansion tanks come pressurized to 12 – 40 psi, but before you install the tank you have to match the system pressure. Start by removing the protective cover from the air valve on the tank. Use a tire gauge to check the pressure. Use a bicycle pump, or compressor, to fill the tank to match the system pressure you noted earlier.
