Make a Cookie Tin Waterer Heater. Under $10, & 10 minutes!

You can make your own waterer heater for use with either metal or plastic waterers. It will cost less than $10, cost pennies to run and you can complete the project in under ten minutes.
Winter brings many challenges for the backyard chicken-keeper, and frozen water is chief among them.  You can make your own waterer heater for use with either metal or plastic waterers. It will cost less than $10, cost pennies to run and you can complete the project in under ten minutes!

Make your own waterer heater for use with either metal or plastic waterers. It will cost less than $10, cost pennies to run and you can complete the project in under ten minutes!We had record-breaking, sub-zero temperatures for long periods of time in 2010 here in Connectictut and my waterers never iced over the way they used to without these heaters.  It doesn’t seem as though a humble, 40 watt lightbulb should be able to produce enough warmth to keep the water in a plastic waterer from icing over, but remarkably, it does!

Supplies:

  • 10″, metal cookie tin (available at most dollar & thrift stores & likely in your garage or basement)
  • lamp assembly kit (available oniline, at hardware & home improvement stores OR buy a thrift store/tag sale lamp and take it apart)0
  • 40 watt, incandescent light bulb (in deep-freeze conditions, use a 60 watt bulb)(in light of the government phase-out, some users recommend 40 watt candelabra bulbs or CFL bulbs, but I have not, so I cannot vouch for their effectiveness)
  • Drill with 3/8″ drill bit
Lamp assembly parts.

INSTRUCTIONS:

1. Drill a hole in the side of the cookie tin.
2. String the pre-threaded lamp stem assembly through the hole & tighten the screw on the stem.
3. Screw in the light bulb. Voila!String the pre-threaded lamp stem assembly through the hole & tighten the screw on the stem.Screw in the light bulb.

TO USE:

Put the top on the cookie tin and place the tin on a cinder block or another level surface in the chicken run.  Plug into a GFI outlet. Place metal or plastic waterer on top of the water heater when freezing temperatures are anticipated. Disconnect when not in use or use a ThermoCube to turn the unit on when temperatures reache 35°F.

I was only convinced the first frigid morning I went out into the run and found no ice ring to chip out of the waterer. You may have to try it to believe it too.

This heater is a lifesaver! Couldn't find a tin the right size though and fastened a pizza pan to a metal dog bowl with screws! Still around $10. Getting arctic in WI. 40w bulb didn't cut if for us, 75 or 100 keeps water from freezing through any temps here!

The problem is the heat build up. Use a lower wattage bulb. If that doesn't help try using a larger tin.

First I would not use a 100 watt bulb, too much heat. Nothing above 75 watts if your're having a problem with the bulbs burning out it is because of too much heat down size your bulb accordingly. Remember the smaller the tin enclosure the hotter it will get. Try to use one at least 10 inches tall. Heat rises so it wont cause any problems with the design. I used a popcorn tin which is about 12 inches tall and it works great and the bulb lasts just fine. When you assemble your heater locate the bulb closer to… Read more »

This is one of the most helpful ideas I have seen since we began keeping hens about two years ago. FYI – I found my tin at a Dollar Tree for $1.00 🙂 Thank you so much for the great idea!
