Abstract
A heating pad for example for animals particularly piglets in a farrowing crate comprises two vacuum formed sheets which lie parallel one on top of the other with a shallow compartment therebetween. A pipe where heating fluid passes into the compartment through the lower sheet and wraps around a number of projections in the lower sheet which extend from the lower sheet up to the under surface of the upper sheet. The pipe is of a flexible elastomeric type resistant to corrosion so that the pad is thus heated by a warm liquid such as water which provides a very simple economic device resistant to damage.
