air to water
An atmospheric water generator (AWG) is a device that extracts water from humid ambient air. Water vapor in the air can be extracted by condensation - cooling the air below its dew point, exposing the air to desiccants, or pressurizing the air. Unlike a dehumidifier, an AWG is designed to render the water potable. AWGs are useful where pure drinking water is difficult or impossible to obtain, because there is almost always a small amount of water in the air that can be extracted. The two primary techniques in use are cooling and desiccants.
The extraction of atmospheric water may require a significant input of energy. Some AWG methods are completely passive, relying on natural temperature differences, and requiring no external energy source. Biomimicry studies have shown the beetle Stenocara gracilipes has the natural ability to perform this task.

I'm in my new build 2 years and the shower pump has died.
I have an air to water unit downstairs is in the utility which I've been told is unvented and pressurised. The cold water feed into this cylinder is from the attic tank, not the mains as I turned off the mains stopcock to see if hot...

Hi
Has anyone got any experience of these. I especially need to know how noisy they are from practical experience, not from Db figures which I don't understand. Also how reliable?

They are cheap, maybe too...
