I need to buy a metal bucket (galvanized) with a cover. I will use it
in conjunction with a fishtank water heater as a water filled source
of radiant heat for a chicken coop for this coming
winter. Unfortunately, I cannot seem to find any store that sells
them, everyone now sells plastic buckets.


Got another idea for you. It's what my dad used to use. He just
mounted a big honking resister to a small board and covered it with an
upside-down metal bread pan screwed down to the board. I'm not sure of
the exact value of the resister, but it is not really critical. It was
one of those ceramic types about the size of your thumb. Also just
drill a bunch of holes in the bread pan so the heat can get out. It
serves as a heat shield. It can be mounted on a sidewall next to the
nesting boxes.

The resistor would have to be hot enough to be a fire hazard...

space heaters are nothing but resistors and blowers, by the way.


Use the type of resistor with an aluminum housing which mount directly
on a metal enclosure using heatsink compund and screws. The
temperature of the resistor needs to only be a few degrees higher than
the desired air temperature. The chance of a fire hazard even if
flamable material comes in direct contact with the resistor is about zero.
