First time posting here.
I've been burning coal going on my 4th season.
I finally have a mystery, hope someone can help.
Like the title say's, I built a new chimney cap this year because the old one rotted away.
Now my house does not get hot. I had the stove (harman MKI) Burning at 525 degrees this weekend and my kitchen where the thermostat is one room away will not go over 70 If I were burning that hot last year it would be 76-80 degrees.
My old cap was about 8 inches from the chimney pipe to the cap top surrounded by screen mesh.
My new home made cap is Stainless tube 14 inch dia. 18 inches high with 2" holes all over it. The base plate under the cap is completely sealed. Can this make a difference in my house temp?
I closed the barometer flap to burn hotter but the house just will not heat up any higher. At this tempature in my 1600 ft.ranch house the bedrooms and bathroom are ccccold. But not the last three years.
I hope the pic works.
