The hybrid heat pump boiler system 1 comprises an indoor module 100, outdoor module 200, hydro module 300, water tank module 400 and a boiler module 500. The indoor module includes an indoor expansion valve 120 and an indoor heat exchanger 110 and is configured to selectively cool/heat air in an indoor space. The outdoor module includes a compressor 210 and an outdoor heat exchanger 230 whereby refrigerant supplied from the outdoor module is passed to a heat storage water heat exchanger 310 of the hydro module to transfer thermal energy to heat storage water in a hot water tank 410 of the water tank module. The boiler module selectively heats heating water received from a floor heating unit 600 to provide floor heating and mains water supplied by a cold water supply pipe 413 to provide domestic hot water. During floor heating, heating water passes from the floor unit through the hot water tank to the boiler unit and during domestic hot water heating, mains water passes to the boiler unit through the hot water tank. By passing through the hot water tank prior to being received by the boiler, heating water and mains water are preheated. |
