Abstract
A de-aerator for removing dissolved gasses from water in a water heating system and a water heating system comprising such a de-aerator are disclosed. The de-aerator includes a vessel defining a chamber for receiving water which has been heated by a primary water heater, an inlet through which water can be supplied into the chamber and an outlet through which the water can exit the chamber; and a vent through which gas can exit the chamber. A diameter of the chamber decreases in a direction from the inlet towards the outlet. The chamber side wall being curved and having a non-constant radius of curvature, the radius of curvature being smaller near the outlet than near the inlet, so that water supplied into the chamber is accelerated as it flows from the inlet towards the outlet, to thereby promote de-aeration of the water. De-aeration gasses exit the chamber through the vent.
