Winterizing stock waterers
Winter is coming and it’s time to inspect stock waterers.
Ken Williamson, agriculture engineering technologist with Alberta Agriculture, says a study by the Prairie Agricultural Machinery Institute shows waterers can cost from $24 to $100 a year to operate.
When doing a fall inspection, remember to check the following:
- Many older waterers have poor insulation in the base. New rigid Styrofoam should be installed.
- Weather stripping and caulking. A base that allows the wind to blow through will use a lot of electricity.
- Use a trouble light to ensure the electrical outlet has power. Plug the heat tape in and hold a plastic bag full of ice against the thermostat to see if it will turn on.
- Set the thermostat as low as is practical.
- Check the float valve.

Nytro Ag Corp and Green Lightning recieved an innovation award at Ag in Motion 2025 for the Green Lightning Nitrogen Machine, which converts atmospheric nitrogen into a plant-usable form.
Williamson suggests that worn out units be replaced with an energy efficient or energy-free waterer. “Energy efficient, electrically heated waterers use extra insulation, more direct heating of the water and optional floating covers to reduce heat loss.”
Many energy free waterers have proven successful in cold prairie conditions. They work like a thermos bottle and rely on retaining heat in the water. They use lots of insulation, floating covers and ground heat.
If considering one, choose a design appropriate for the prairies and size of the herd and install it properly.
If replacing an old unit with an energy-free one, install a heat tape on the water supply line. Otherwise, the small riser pipe could freeze.
