No, if you have a pre existing fireplace it makes sense to install an insert.
yes big dan, it is a chimney on an internal wallis It an external chimney?
building codes are a consideration. you can do whatever you want weather it is safe and passes inspection is another story.Or, one could place a stove instead of an insert into a fireplace.
so is it a question of the rate of heat transfer into the room being faster with a freestanding stove?In an interior fireplace with block-off plate and insulation above, no. In an exterior fireplace you may lose some heat to the outside through the back of the fireplace. If there is enough room you can put Roxul around the insert which will reduce that heat loss. Another point that let's people think inserts provide less heat: The masonry will take up some of the heat so they may think the insert provides less heat. However, that heat will also be radiated to the room later.

the big plus side of an insert is it fits into an unused fireplace rather than taking up a bunch a room like a free standeryes big dan, it is a chimney on an internal wall
thanks grisu. So which would you recommend?Exactly. What you get with all that masonry is free thermal mass that will even out the temp swings. Usually people pay extra for that by buying a soapstone stove.
yes, that is exactly the quandary I have - whether to extend the hearth and bring the face of the fire into the room which may not be great aesthetically, or go for the insert which seems not to have the same response time but may look better.the big plus side of an insert is it fits into an unused fireplace rather than taking up a bunch a room like a free stander
good point.Exactly. What you get with all that masonry is free thermal mass that will even out the temp swings. Usually people pay extra for that by buying a soapstone stove.
my concern was that I would be wasting energy burning timber that would not be heating the house but having thought about your response I can see that the thermal heat sink of the masonry, especially as its an internal wall, is the balancing factor. on that basis I think I will go with the insert which will fit better with my room designExactly.
