Heatwave unit warms cold milk as it moves through to protected nipples. There is always a supply of warm milk available to the lambs which reduces overconsumption.
If it is used in a very cold barn, a small ceramic heater in the tank will keep the lines from freezing. The unit is in like new condition and comes with a full selection of extra fittings,hoses,nipples and valves. It works very well and can be used without the heating unit on if desired.
