We are in the process of adding a washrack in our barn. We would like to just have a hydrant in the wash rack, but would also like to have hot water. In the winters we are very cold so what is the best options to have hot water in a washrack that would only be heated say the 3 or 4 times a winter we would be washing in it. Would also like suggestions for other must haves in a wash rack if you were starting over. Size will be 12x19.
