Winter Waterer Sizer
Frozen water is the winter chore that breaks flocks' routines and keepers' patience. Put in your flock and how cold your nights get, and this sizer matches the numbers our heated waterer guide and the base-vs-integrated comparison defend in print: daily gallons, the heater class actually rated for your lows, refill intervals, and what a winter of electricity costs.
Your winter water plan
| Water per day | |
|---|---|
| Heater class rated for your lows | |
| Refill interval (2 / 3 / 5 gal reservoir) | |
| Winter electricity, worst case | |
| Winter electricity, typical (thermostat cycles) |
The math behind the numbers
- Daily water: the standard planning figure of 1 gallon per 4–5 standard birds per day (~0.25 gal each). Bantams drink less; a dry heated coop pushes intake up.
- Temperature floors are maker specs: the leading heated base is rated to 10°F, the integrated heated fountain to 0°F, the heated nipple drinker to −10°F. Below a rating, no electric unit's number holds — plan warm-water swaps as the backup.
- Electricity: worst case = nameplate watts × 24 h × 120 days, at $0.15–0.20/kWh. Typical assumes the thermostat cycles ~40% duty in a moderate winter. All units compared here are thermostatically controlled; always-on no-name bases cost more and gain nothing.
- Water intake can rise sharply with heat or dry air — see eXtension, water requirements of poultry.
