Adjective; a word used by heating engineers to describe a simple maintenance task which results in unexpected but significant savings on heating bills. Often used in the same sentences as "carbon neutral", "green energy", "why has demand for our gas gone down".
I think you mean Stanage as a noun. As in "Thanks to my stanage on the boiler, my gas bill is now zero."
If you try to use it
adjectivally, it doesn't work.
How it can describe a noun, which is what an adjective does.
"Today I visited a customer who has a stanage central heating pump."
Or,
"Today I did a stanage pump replacement."
Doesn't really work does it?
So to me there ought to be a verb, "to stan", which would give you "stanning" both the present participle and adjectival use.
"Whatever you do don't stan that tap."
"All day long I was stanning in the kitchen".
Or "Mate, you have made a right, stanning job of it, the mop and bucket are in that cupboard over there."
Past Participle "stanned", as in "Who the flip has stanned in this room?"
"Stannish" could also be an adjective.
"That mess looks pretty stannish to me."
(This is only of interest to anyone with an interest in linguistics,)
"Stanage" has the ending -age which normally is a noun that comes from a verb, like leak - leakage, or can also be used as a verb, like garage, which comes from the French verb "garer" which means "to park" (and probably has some link with the word "gare" which means "station".)
Other nouns would be like roughage, plumage, triage which again comes from a French verb "trier" = "to sort out".
"Plumage" weirdly comes from "plume" which as we all know is the French for "feather" and comes from the act of plucking, so seems to be a misnomer.
"Roughage" is a relatively modern word coming more from the adjective "rough" than from the verb "to rough" which on its own is meaningless, as it needs to be followed by a preposition. So, "to rough out" makes sense as does "to rough up".
Sabotage, again from a French verb. (A "sabot" is French for a clog and workers would sabotage machinery by chucking a clog into it, the verb being "saboter")
Anchorage, from to anchor.
Coinage
Cooperage
If you want a full list many of which you will not know, as I too didn't, BUT as I do know, many of which come from French.
