Commercial water heating energy use wastes 30% of its energy due to poorly controlled recirculation pumps. The AutoHot system is able to deliver hot water only when there is a demand, eliminating the waste of energy or water. Recent codes changes now require on-demand recirculation such as California’s Title 24 and the IECC 2015 model code adopted by most states. Here’s how it works:
