A method is provided of temporarily providing hot water to a hot water pipe 16 of a faulty combination heating and hot water boiler unit 12 via an electrically-operable standalone water heater unit 18. The method comprises the first step of providing a secondary flow path S which extends from a primary flow path P defined by the hot water pipe and spaced from the faulty boiler unit, and a tertiary flow path T which extends from the primary flow path downstream of the secondary flow path. The method comprises the second step of temporarily providing the standalone water heater unit externally of the faulty boiler unit, and temporarily connecting the secondary and tertiary flow paths with a cold-water inlet port 76 and a hot-water outlet port 78 of the water heater unit respectively. The method comprises the further steps of diverting water flow from the primary flow path into the secondary and tertiary flow paths, whereby water flow passes through the water heater unit, which is energised so that water flow returning to the hot water pipe along the tertiary flow path is heated. A temporary hot water system 10 for such a method is also provided. |
