What is circulating?
Circulation as such essentially means a circle. A constantly recurring phenomenon. This term is often used by plumbers. Thanks to circulation, there is no need to wait for the water to warm up in the battery but to use hot water basically immediately. But it is not a system of savings, rather the opposite. This is mainly a matter of comfort rather than a necessary necessity. The water taken over the modern battery is heated rather quickly and the downtime is only very short.
