A splitter valve for splitting a single fluid stream into two streams. The valve is primarily intended for a DCHP system having a burner for a Stirling engine and a supplementary burner. The valve comprises a vane (5) rotatable through a range of positions across an orifice (10) to vary the ratio of the single fluid stream diverted to the two streams. The orifice is profiled such that there is a substantially linear relationship between the angular position of the vane and the ratio of the fluid diverted to the two streams. A laminarising device, such as a perforate plate (4) or constriction (13) may be provided on the two streams downstream of the vane (5).
