Claim: Interior humidity makes heating more efficient?
I came across a claim that humid air ‘holds more heat’ and therefore makes heating more efficient (e.g. furnace will run less often).
Here is a link to a page that makes a similar claim: https://www.griffithenergyservices.com/articles/humidity-affects-home-manage#:~:text=Humid%20air%20holds%20heat%20more,to%20continually%20replenish%20indoor%20heat.&text=Balanced%20humidity%20also%20safeguards%20your%20indoor%20air%20quality.
This feels like classic misconstruction of the basic science, but maybe I am missing something. Is this a ‘thermal mass’ claim, which I can only imagine would be beyond negligible; or is it something else?
Obviously there are reasons we want RH to be within a certain range for comfort and condensation issues, etc. but heating efficiency?
