This week’s project is improving the heat transfer from our massive double sided fireplace. It has a steel firebox with a very basic heat exchanger. Airflow through the heat exchanger is poor. I’m adding a blower in the basement to draw air from a nearby register and force it up over the firebox, out the vents on top.

Basically trying to squeeze every single bit of efficiency possible out of a very inefficient heat source since I don’t currently have the time or money to install an insert.
