A water heating apparatus for supply of heated water to an installation comprises a combined heat and power (CHP) unit, a heat storage means, and a secondary heating device. The CHP unit and the secondary heating device are arranged to operate in a first mode where the CHP unit provides heat to the heat storage means and the secondary heating device provides all the heated water required to meet the heat demand of the installation; and to operate in a second mode where the secondary heating device is inactive, and the heated water to meet the heat demand is provided by the CHP unit and/or from the heat storage means. |
