Title: A DOMESTIC HOT WATER INSTALLATION AND METHOD OF OPERATING SAME
Abstract:
This invention relates to a domestic hot water installation and a method of operating same. The domestic hot water installation comprises an external heating circuit. The external heating circuit includes a heat source and a heat exchanger. The heat source is either a boiler or a heat pump. A controller receives temperature readings from a plurality of temperature sensors and controls a pair of variable speed pumps, one on the primary side of the heat exchanger and one on the secondary side of the heat exchanger, to provide hot water to a hot water outlet, which may comprise a hot water cylinder, a hot water tap module or the like, at a desired temperature in a tightly controlled manner. The pumps are operated so that changes in the additional equipment connected to the heat source will not have an adverse effect on the provision of the hot water in the domestic hot water installation.
