Thermal numeracy refers to understanding the quantities of heat produced, emitted, and transferred in various physical phenomena.
- Fireplace heat loss from chimney can be 80-90% - [1]
- At high temperatures, temperature in degrees F is about 2x that of degrees C. Specifically, ~9/5 times.
- Glenwood 5000 stove is rated for 100k BTU, with 11 sf of heat exchange area - about 10k BTU/SF
- 1 kW ~ 3000 BTU/hr
- Black pipe is only $12/square foot (10k BTU) of heat exchange area using 1" pipe!
