I have an NC30 third year burning, Went through a few stoves finding the right one. NC13 not enough, Downdraft stove touchy to run, How much do the side heat shield cut down the intense radiant heat coming off the sides. I have 1600+ ft with 30 feet to the peak and 12 foot side walls so it's bigger area than it sounds in terms of airspace. I kept comfortable last year with smaller loads but 10-15 feet from sides seems to have a much higher temp. Would the shields knock down some of the radiant heat? Advice welcome
