The rash informality in home circles (7)

Ross

I believe the answer is:

hearths

I'm a little stuck... Click here to teach me more about this clue!

'home circles' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps you can see a link between them that I can't see?

'the rash informality' is the wordplay.
'the rash' anagrams to 'HEARTHS'.
However, I am unsure how this is indicated.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for hearths that I've seen before include "Firesides" , "Fireplace areas" .)
