Do you need a heater in Michigan?

Yes. With highs at or below freezing on about 51 days a year and 6 nights below zero, an unheated bath is ice for weeks. Choose a de-icer rated for the bath size, and a deeper basin keeps heat better than a shallow dish. Wind matters as much as temperature: put the bath out of the prevailing wind if you can.

Set up a heated bath safely

  • Plug into a GFCI-protected outdoor outlet. Use an outdoor-rated extension cord only if you have to, and keep the connection off the ground.
  • Choose a de-icer with a thermostat and automatic shut-off if the bath runs dry.
  • Keep water no deeper than 2 inches at the edge so small birds can stand.
  • Never add antifreeze, salt or glycerin. They harm birds and do not keep water drinkable.
  • Top up often. Heated water evaporates faster, and a dry de-icer can damage itself or a plastic basin.
