This past spring we had a local hearth store install an insert in our living room thinking it would have been able to keep the whole house warm. boy oh boy was the dealer and me wrong. The insert keeps the living room and kitchen somewhat warm but the rest of the house we need to run small electric heaters. with the latest cold snap were even having a hard time keeping the main lvl of the house warm. I find one of the biggest problems is the coal bed gets too big that i can only fit 3 splits in the already small insert. I find the stove gets hotter with the air closed off fully but the coals last so long. Do you think it would be better to open the air fully after the stove starts to cool to burn of the coals faster? Im really wishing I would have either put a big free standing stove in the finished basement or even went with a heat pump. On a positive we have still only used half tank of oil so far this year but I was hoping the stove would have made the house warmer. Before anyone asks most of the wood I have been burning is very dry it has been left from the previous owner 3.5 yrs ago.
