Abstract

Disclosed is a hot water system (50) comprising a water storage tank (14) and an instantaneous-type water heater (12). The storage tank (14) has an inlet (22) in fluid communication with the outlet (20) of the instantaneous-type water heater (12) and an outlet (24). The inlet (18) of the instantaneous-type water heater (12) is in fluid communication with a mains water supply (26). The water heater (12) is adapted to energise in response to a flow of water through the water heater (12). The hot water system (50) also includes a first pump (52), with an inlet (56) in fluid communication with a second outlet (54) of the tank (14) and an outlet (60) in fluid communication with the inlet (18) of the water heater (12), and a controller (42). The controller (42) is adapted to, upon user instruction, energise the first pump (52) and cause water to be directed from the outlet (20) of the water heater (14) to the inlet (22) of the tank (14) and from the second outlet (54) of the tank (14) to the inlet (18) of the water heater (12) in order to heat the water in the tank (14).
