Abstract (en)
[origin: EP3415836A1] A water heater that is a circulation pipe system includes a heat exchanger configured to heat water, a hot water storage tank configured to store the heated water, a circulation pipe through which water is circulated between the heat exchanger and the hot water storage tank, a hot water supply pipe through which the water stored in the hot water storage tank is supplied, a bubble injection device provided at an upstream side of a flow path communicating with the heat exchanger in the circulation pipe and configured to inject bubbles into the water, a carbon dioxide supply device connected to the bubble injection device and configured to supply bubbles containing carbon dioxide, and a controller. The controller is configured to control the bubble injection device, the heat exchanger, and the carbon dioxide supply device such that the bubbles containing the carbon dioxide are intermittently injected into the water.
