I am going to install a 4000 watt wall heater to an add on. It is the kind of wall heater that is seated in the wall. i also plan to install insulation in between my wall studs. there will be insulation above and below the wall heater. Is insulation flammable? and will/Should I put something on the two ends of insulation? some kind of foil or something?
Also just a quick question its a 240 volt heater. I have bought 10/2 wire for it. will that work? and what kind of breaker should i use?
