Hello....first let me say I am new here and considering a BK Princess or a Ideal Steel Hybrid stove to heat my 1800sq ft. double wide home. It was a eye opener to see how far wood stoves had advanced! I have burned wood my entire life using everything from plate stoves to a Wood Master boiler. The boiler served me well for 25 years but finally gave it up this past year. I do not want to play the boiler game again so here I am. I am looking for a SOLID 12-14 hr burn time as we both work.The Princess will achieve this. 40 hr burn times mean nothing to me really as I am looking for day to day consistency.The Ideal Steel stove real world burn times? Do you have to wait till the fire burns completely down in both models before you add wood? What are the chimney height requirements for both?I have access to unlimited amounts of Oak,Ash and Hickory so wood quality will not be a issue. In fact I have approx. 30 rick of seasoned oak and ash waiting to be burned.Thanks in advance! Rick
