The funnel aperture enables water to be poured into the reservoir and its shape enables condensation to run back into the reservoir. The funnel also comprises a plurality of holes 120 through which the steam exits and reduces the pressure of the steam and reducing its temperature. The holes may adjusted to selectively open or close some or all of the holes. Adjustment may be a cover or lid lifted or turned.
