Just s&c or hardwall it. hardwall is only qualified for c50degC however I've used it in my own house and not had so much as a hairline crack ( do have a good 4 inches air gap all round though) The trick is to leave it to dry naturally for as long as practical before you ramp up the stove/wood burner whatever and when you do, don't max out straight away. Not sure how this would cope if stove was right next to wall though.....
I did this for a customer last summer who chose the hardwall option after I gave him the price of vitcas!
Oh, if possible leave the rear brick exposed....presuming it's brick! Looks tonnes better and generally the surface closest to the stove.
