Just a thought on house insurance policies. There may come a time when any stove but an airtight may not meet the insurer's standards and void the insurance policy. There are airtight cookstoves on the market.

My grandmother cooked on a woodstove till she was 85 years old. They do not provide instant heat but the stove has a lot more surface area with more variable heat areas to work with and provide the knowledgeable cook more latitude.
