De-icers for this climate
Our de-icers are 120V and sold for US and Canadian outlets. Check the wattage against the bath size on each listing.
Stainless Steel Pond and Birdbath Deicer
A stainless steel dome heater that sits in a pond or large birdbath and keeps a patch of water open through freezing weather, so birds can still drink and bathe in winter. It has a built-in thermostat and a dry-run cut-off that switches the heater off if it's left out of water. Dimensions: 180 mm (7.1 in) across, 83.9 mm (3.3 in) tall Material: stainless steel dome, black power cord Power options: 100W, 150W, 200W, 250W or 300W. Smaller birdbaths need less power; ponds and very cold areas need more. Weight: about 1.9 kg (4.1 lb) Plug: US 3-prong, 120V Use with a GFCI-protected outdoor outlet. Keep the cord out of reach of pets and away from where people walk.
70W Trough and Bath Deicer
A 70-watt submersible deicer that keeps a small open-water area in a bird bath or livestock trough through hard freezes. Runs on standard 120V US household power with a thermostatic control that switches on near freezing and off when the water is ice-free, so it does not run continuously.Specs: 70 W, 120V US plug, submersible sealed element, black housing. Sized for small baths and troughs; it keeps a drinking hole open rather than warming the whole bath — birds only need liquid water, not warm water.Safety note: this is an electrical appliance used outdoors in water. We list it only once a valid UL/ETL safety certification is confirmed. Always plug into a GFCI-protected outdoor outlet and route the cord so birds and pets cannot chew it.
Birdbath Deicer with Auto Shut-Off
A compact birdbath deicer with a built-in thermostat and automatic shut-off. It sits in the basin and keeps a patch of water ice-free so birds can drink through winter — liquid water is harder for birds to find than food in a hard freeze.Specs: thermostatically controlled (activates near freezing, shuts off automatically), US plug, white housing that blends into light-colored basins.Safety note: this is an electrical appliance used outdoors in water. We list it only once a valid UL/ETL safety certification is confirmed. Always use a GFCI-protected outdoor outlet, and never run it in a dry basin.

Do you need a heater in Indiana?
Yes. With highs at or below freezing on about 35 days a year and 5 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.
