Abstract: Disclosed is a burner vessel (5400) for a hybrid electric-combustible fuel fluid heater arranged to heat fluid in one or more fluid circuits. The vessel comprises a vessel housing (5401) containing: a combustible fuel burner (5405) arranged to burn combustible fuel; and one or more electric heating elements (5410) arranged to generate heat and transfer the heat to said fluid in one or more fluid circuits. The vessel further comprises: a first cold fluid inlet (5404) arranged to input relatively cold fluid to the vessel; a first hot fluid outlet arranged to output relatively hot fluid from the vessel; a first fluid duct (5403) extending between the first cold fluid inlet and the first hot fluid outlet and arranged to convey fluid through the vessel; and a flue (5407) arranged to convey waste combustion gas from the vessel. Both the combustible fuel burner and the one or more electric heating elements are arranged to heat fluid in the first fluid duct.
