An automatic waterer refills from a buried water line through a float valve, and a heater under the trough keeps it ice-free. The trough is small, 1.5 to 20 gallons, because it refills as animals drink. Size one by the head count the maker gives rather than the trough size. Most install on a concrete pad over the supply line and are wired in by an electrician, so budget for the install as well as the unit.
