>Butane is not a //bad// fuel, just a less practical one in real life for many of us. Among other things, it’s often more costly, [and] not as easily or widely available in larger-sized tanks... -- P. Rowe((https://juxtamorph.com/butane-versus-propane-which-is-hotter/))

====== Butane ======

Butane (not to be confused with [[fuel:isobutane|isobutane]]) is the most popular gaseous fuel after [[fuel:propane|propane]].  Fuel is available with other camping supplies.  8oz [[https://amzn.to/2yNtCfj|Butane canisters]] are also available, and often cheaper, in Asian grocery stores where they are popular for countertop stoves.

Butane is not practical for use below freezing -- it won't vaporise below ~33F((propane vaporizes down to ~-43F)).  

Stoves are available which will [[https://amzn.to/3aV1uoA|burn either propane bottles or butane canisters]]. 

===== effects on humidity =====

As with all fossil fuels, burning butane cleanly releases water vapor and CO2.((https://en.wikipedia.org/wiki/Butane#Reactions))  The former can increase interior [[hvac:dehumidifier|humidity]].


==== carbon monoxide ====
As with other fossil fuels, burning butane in low-oxygen environments will emit [[fuel:carbon monoxide|carbon monoxide]].((https://en.wikipedia.org/wiki/Butane#Reactions))
