Latent heat of vapourisation of water is ~ 2.3KJ / Kg so the amount of recovered heat for 9.5L is about 22KJ in 24 Hours. About 1KWh so the 230W is almost quadrupled for heating the room.

Thanks - that's the figure I wanted. Though in my experience it never removes anywhere near the maximum quoted volume of water.
