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

'domestic device' is the definition.
'gas heater' can be an answer for 'device' (gas heater is a kind of device). I'm unsure of the 'domestic' bit.

'cut apple?' is the wordplay.
'cut' becomes 'gash' (a gash is a wound or cut).
'apple?' becomes 'eater' (I've seen this before).
'gash'+'eater'='GAS-HEATER'

Can you help me to learn more?

(Another definition for gas heater that I've seen is " Domestic warming appliance".)

I've seen this clue in The Telegraph.
