What Is an Atmospheric Expansion Tank? | Condo Heating Explained
If you're on a condo board or manage a multi-family building in Calgary, you've likely seen an expansion tank listed in a mechanical proposal — but what exactly does it do?
In this video, we walk you through the role of an atmospheric expansion tank in your condo’s heating system. Using an easy-to-understand analogy (think tire pressure on a cold day), he explains how this component helps regulate pressure changes as water expands and contracts with temperature.
You’ll learn:
What an atmospheric expansion tank is
How it works in relation to heating media
Signs something might be wrong (like being waterlogged)
What we do during regular maintenance to ensure system stability
Why piping location matters for optimal performance
This is part of our Condo Resource Library – a series of short, no-jargon videos designed to help Calgary condo boards and property managers make informed decisions about mechanical systems.
