Mr. Egan means heat as regards an animal being in heat rather than heating water. Sorry. I misunderstood. There are collars that have to be put on animals, and I accept that these and be put on and taken off. There are also boluses used for that, which are put into the cows' stomachs. They are most definitely permanent fixtures which do the same job.
