Anybody out there use these as regular cookstoves? My mom's 60+ yr old Findlay Oval has finally given up the ghost (firebox is done for) and we've been wanting to get her an airtight one anyway. She uses it for heat and cooking 7 months of the year. Looking at Heartland, Meal Time and Enterprise-Fawcett cookstoves, but wondering if anyone uses these others as cookstoves and how you find they work compared to the more traditional cookstoves. Would love other suggestions too but it needs to be CSA(EPA) certified in order to qualify for govt. rebates.
