Just to let you know your heat exchanger grate is fantastic and works like a dream. Believe it or not it is fairly chilly here on the coast. 56 degrees, foggy with mixed rain. We have been heating our entire 750 sq. ft. house today and tonight only with the fireplace and your grate to a toasty 78 degrees with so much less wood then we used in the past. Thanks for a superior quality built product.
