I had the surround off my insert to look at how I was going to insulate around it. Then it got cold and I needed a quick fire to take the chill off.
With the stove at about 425 and the blower running. The metal part of the heat-a-lator that the insert seats in was at 120 or so on the sides and 170 on the top.
This sets in a cinder block chimney chase. All the heat the goes to the cinder block goes up and out of the house due to a pretty sizable air gap between the heat-a-lator.
Assuming the metal is R-1. That's probably accurate. And assuming the temperature of the block is 40. A guess but probably pretty accurate. That's a delta of between 80 and 130
Say 15 square feet exposed. That's 1200 to 2000 btu's an hour wasted.
