2 years ago I purchased an elegance 36. I have burned a lot of Poplar which is a default in Saskatchewan. Last year I acquired white ash from a fellow neighbors tree and have noticed the burn rate and heat output is significantly different. If you can get your hands on White ash here it burns almost twice as hot with 1/3 of the required logs. If I use an IR gun with minimal ash firewood my soapstone is at 800°, to 1,000° f I need to use four or five similar pieces of Poplar just to get it up to 500 degrees Fahrenheit
